What is the Size of a PowerPoint Slide in Pixels?

By: Author Shrot Katewa

When creating a PowerPoint presentation, it is essential to determine the appropriate size for your slides. Understanding the size of a PowerPoint slide in pixels is crucial to ensure that your presentation looks great on all devices, from desktops to mobile devices.

The standard size of a PowerPoint slide is 1024×768 pixels and the widescreen PowerPoint slide is “1920×1080” pixels. It can also be adjusted based on your preferences or the requirements of the platform on which you plan to present your slides.

In this article, we will discuss the standard size of a PowerPoint slide in pixels or inches as well as how to adjust it to fit your needs. Let’s get started!

1. What is the Size of a PowerPoint Slide in Pixels?

In Microsoft PowerPoint, there are multiple preset slide sizes available. You can also customize the size of the slide using the “Custom Slide Size” feature available in the application. Depending on the slide size you select, the size of the slide in pixels will vary.

1.1 What is the Size of a PowerPoint Standard Slide in Pixels?

The “Standard (4:3)” option in Microsoft PowerPoint used to be the only size option in the beginning since most screens from 2010 and before were that size. The standard slide size in PowerPoint is “1024×768” pixels. 

1.2 What is the Size of a PowerPoint Widescreen Slide in Pixels?

In Microsoft PowerPoint, the default size of the slides is the “Widescreen (16:9)” option. The widescreen PowerPoint slide is “1920×1080” pixels.

2. What is the Size of a PowerPoint On-Screen Show Slide in Inches?

In Microsoft PowerPoint, the size of the slides is mostly measured in inches. Using the “Slide Size” dialog box, you can check the dimension of a slide in inches. Depending on the type of the selected slide, the slide size varies. There are three different “On-Screen Show” slide sizes available in Microsoft PowerPoint.

2a On-Screen Show (4:3)

The “On-Screen Show (4:3)” slides are “10×7.5” inches in size. This is the “Standard” slide size.

2b On-Screen Show (16:9)

The “On-Screen Show (16:9)” slide size is “10 x 5.625” inches in dimension. This is the “Widescreen” option which is the default slide size in PowerPoint.

2c On-Screen Show (16:10)

The “On-Screen Show (16:10)” slides are “10 x 6.25” inches in width and height respectively.

3. How to Find the Size of the Slide in Inches?

Using the “Slide Size” dialog box in Microsoft PowerPoint, you can find the size of the slides in your presentation in inches. To do so, follow the 3 quick steps.

Step-1: Click on the “Design” tab

In the menu ribbon located at the top of the screen, click on the “Design” tab. This will open the “Design” menu.

Step-2: Click on the “Slide Size” option

In the “Customize” group of the “Design” menu, click on the “Slide Size” option. Then click on the “Custom Slide Size” option in the dropdown menu under the “Slide Size” option. This will open a dialog box.

Step-3: Click on the “OK” button

In the “Slide Size” dialog box, you can now see the size of the slide in inches in the “Width” and “Height” boxes. Then click on the “OK” button at the bottom of the dialog box to close it.

4. How to Change the Size of a PowerPoint Slide?

In Microsoft PowerPoint, you can change the side of the slides using the “Design” menu. However, you can only change the size of all the slides in a presentation at once. To change the size of the slide in PowerPoint, follow the 3 simple steps.

The first step is to open the “Design” menu. To do so, click on the “Design” tab in the menu ribbon located at the top of the screen.

In the “Customize” group of the “Design” menu, you have to now click on the “Slide Size” option. This will open a dropdown menu containing the preset slide size options available in PowerPoint.

Step-3: Click on your preferred slide size

Finally, all you have to do is click on your preferred slide size option from the preset options available in the dropdown menu under the “Slide Size” option. The available slide sizes are “Standard” and “Widescreen” .

4.1 How to Customize the Size of a PowerPoint Slide?

The “Custom Slide Size” feature in Microsoft PowerPoint allows you to customize the size of all the slides in a presentation. Using the feature, you can set any dimension to the slides in your presentation. To customize the size of the slides in a presentation, follow the 7 easy steps.

The first step is to open the PowerPoint presentation file where you want to customize the size of the presentation slides. Then click on the “Design” tab in the menu ribbon located at the top of the screen to open the “Design” menu.

The next step is to click on the “Slide Size” option in the “Customize” group of the “Design” menu. In the dropdown menu, the default slide size is the “Widescreen (16:9)” option.

Step-3: Click on the “Custom Slide Size” option

Now all you have to do is click on the “Custom Slide Size” option at the bottom of the dropdown menu under the “Slide Size” option in the “Design” menu. This will open a dialog box.

Step-4: Click on the “Slide sized for” option

In the “Slide Size” dialog box, click on the “Slides sized for” option. Then click on the “Custom” option at the bottom of the dropdown menu under the “Slides sized for” box.

Step-5: Click on the “Width” box

In the “Slide Size” dialog box, the next step is to click on the “Width” box. Now you can type in your preferred width of the slides in inches. You can also use the up and down arrows in the “Width” box to increase or decrease the width of the slide respectively.

Step-6: Click on the “Height” box

The next step is to customize the height of the slides. To do so, click on the “Height” box in the “Slide Size” dialog box and type in your preferred slide height in inches. You can also click on the up or down arrows in the “Height” box to adjust the height of the slides to your preference.

Step-7: Click on the “OK” button

Finally, all you have to do is click on the “OK” button at the bottom of the “Slide Size” dialog box to save the custom size for the slides in the presentation file.

Cheat Death by PowerPoint!

What size should my slides be, 16:9 or 4:3?

July 3, 2017 by Laura Foley 2 Comments

Deciding on a slide format used to be easy when there was only one choice. Nowadays, you can choose between 4:3 format or 16:9. What do these numbers mean and which size should you choose for your presentations?

What the numbers mean

The above notation is called the “aspect ratio,” or the ratio of the width to the height of the slide. In the 4:3 aspect ratio, the dimensions are 1024 x 768 pixels (10.67″ x 8″); the height is 3/4 of the width. Back in the Ye Olde Days of PowerPoint, it was your only choice. Why? Because that’s the aspect ratio of actual slides, pictured above, television screens, and early computer monitors.

When high-definition screens came on the scene in the early 2000s, they were built in a 16:10 aspect ratio. But as more and more high-definition screens were manufactured, it became clear that screens with a 16:9 aspect ratio were cheaper to manufacture. So the 16:9 aspect ratio (1920 x 1080 pixels or 13.3″ x 7.5″) became the new standard.

What size should you choose?

From boardrooms to computer monitors to smartphone screens, 16:9 is the default screen aspect ratio so that’s the slide size I always go with. The 16:9 format gives you a lot of slide real estate to play around with! The legacy 4:3 aspect ratio, while still used, creates smaller slides and doesn’t look that great on newer screens.

How do you change an old 4:3 deck to the new 16:9 format?

Oh, this is super-fun to do and you’re a lucky duck if it becomes your job.

To resize your slides go to the Design tab on the ribbon and select Slide Size/Widescreen on the right side of the screen.

After you select the new size, this window will appear:

Now you’re faced with either everything on the slides being stretched out or squished to fill the space. Oh boy! Either way, after you make your selection you’ll need to go through the presentation slide by slide to ensure that everything looks good. This can be fairly straightforward if the creator of the presentation stayed within the template or a real pain in the rear if he/she didn’t. But do go through the deck to ensure that everything looks right.

If you’re a production artist that charges by the hour, reformatting an organization’s slides from 4:3 to 16:9 could be a nice little gig for you!

Other slide sizes for special events

Now, the 16:9 format is great for everyday use but what if you’re designing a presentation for an event? Last year, I was designing slides for a corporate conference where the setup included multiple, massive screens. For that event, the slides measured 52″ x 17″ and had a “leave this space blank” area on the bottom. Each event is different, so if you’re working on slides like these you need to become friends with the AV folks and find out what size slides they recommend for optimal viewing on that particular setup. The last thing you want to see on a gigantic stage are distorted graphics!

Bottom line

Unless you’re told otherwise, use the 16:9 format. You get a lot more space on each slide for your visuals and it’s really the way things are going.

How to Change Your PowerPoint Slide Size (16:9 vs. 4:3)

• PowerPoint Tutorials
• March 10, 2019

In this tutorial, you’ll learn how to change your slide size in PowerPoint.

That way you can create slides for any situation including on-screen presentations, printed documents, posters, postcards, handouts, etc.

First off, the two most used PowerPoint slide sizes are:

• 16:9 ratio  for onscreen presentations and new overhead projectors. This is the default setting for the latest versions of PowerPoint.
• 4:3 ratio  for printing slides on standard 8.5 x 11 pieces of paper as handouts.

When starting with a blank PowerPoint presentation, changing your slide size is super easy and straightforward. If not, there are a few issues you’ll need to deal with, each covered below.

That’s why it’s worth figuring out what slide size you need BEFORE you build your presentation. If you later convert your presentation to a different size, it can be painful!

It’s just like the old carpenter saying, “measure twice and cut once.” In PowerPoint, you’ll want to “ask twice (to double confirm the required size) and build once.”

Changing your PowerPoint slide size does not make your PowerPoint presentation larger or smaller. To reduce your PowerPoint file size, you need to learn how to compress a PowerPoint presentation .

Table of Contents

How to change your powerpoint slide size.

By default, new PowerPoint presentations start in the 16:9 slide size format.

This is the NEW standard for most modern overhead projects and monitors and is recommended for most presentations. That said, you can easily change your slide size to something else.

To change your slide size in PowerPoint, simply:

• Navigate to the  Design tab
• Open the  Slide Size  drop down menu
• Select  4:3 ,  16:9  or  Custom Slide Size  (see options below)

When starting with a blank presentation, you are now good to go. You will not have to worry about any of the conversion issues discussed below.

Notice too, how much wider the 16:9 slide size is versus the 4:3 slide size in the picture below. The new size gives you more room for the content on your slides.

When you are converting an existing presentation to a new slide size, you will additionally be given the following prompt:

“You are scaling to a new slide size. Would you like to maximize the size of your content, or scale it down to ensure it will fit on the new slide?

Maximize  leaves all your content as is on your slide, even if it no longer fits on the new slide size that you selected.

Ensure Fit  scales down your content in proportion to the new slide size you have selected. You will only see this option when moving from a larger slide size to a smaller one.

Custom PowerPoint slide sizes

Choosing  Custom  for your slide size gives you additional options to work with. Inside the dialog box you can choose your size on the left and your orientation on the right.

On top of that, you can also input your own custom slide size. However, I recommend using one of the preset PowerPoint dimension options.

• On-screen show (4:3)
• Letter Paper (8.5×11 in)
• A3 Paper (297×420 mm)
• B4 (ISO) Paper (250×353 mm)
• B5 (ISO) Paper (176×250 mm)
• 35mm Slides
• On-screen Show (16:9)
• On-screen show (16:10)

For your orientation options on the right-hand side of the dialog box, you can choose between  Landscape  and  Portrait .

In most situations, you will want one of the default settings. Best practice is  Landscape  for your presentation slides and  Portrait  for your printed notes, handouts and outlines.

Issues when converting 4:3 to the 16:9 slide size in PowerPoint

When converting an existing 4:3 presentation with content into the 16:9 format, you are not given any conversion options. Instead, PowerPoint simply does the conversion for you, which can create several problems.

There are two issues you will face in the new 16:9 slide size.

The first issue is that all the images on your slide master (including company logos) will be stretched to fit the new, larger slide size.

To fix the stretched images, you will need to fix those images (or reinsert them) on your slide master, as if you were creating a PowerPoint template from scratch.

The second issue you will face in the larger 16:9 slide size is that you will have a lot of extra white space on your slides.

While you can leave the space blank, doing so will make your content look weird. Ideally you don’t want a lot of white empty space like that on your slides. Especially since all your font sizes will be so small.

That’s why if you have the time, I recommend resizing your content to fill in the white space. You can do this by either increasing the font size of your content, or adding additional visuals that support your message.

Issues when converting 16:9 to the 4:3 slide size in PowerPoint​

When converting an existing 16:9 presentation to the 4:3 slide size, you are given the option to either  Maximize  or  Ensure Fit  (both covered below).

1. The Maximize option

This option means that the content on your slides will not be resized to fit the 4:3 slide size. The same is true if you move to any smaller slide size.

Maximize Issue #1:  All the images on your slide master (including your company logo) will be distorted.

You might also have issues with other content placeholders, slide backgrounds or anything else that was built on your slide master.  For these issues, you’ll first need to navigate to your Slide Master. Once you are there, you either adjust (or rebuild) your PowerPoint template so that everything fits properly.

Maximize Issue #2:  Your content will not be scaled down to the smaller slide size. Instead, you’ll have overhanging content as pictured above.

For these kinds of spacing issues, you will need to work through your slides to adjust your content.

One recommendation as you move from the larger 16:9 slide size to 4:3, is to break up your slides. Take the contents from one larger slide and break it into two (or even three) separate slides.

Breaking up your content is preferable to just cramming more content on the smaller slide space. Doing so will make your content easier to read when presented on an overhead projector.

2. The Ensure Fit option

This option means that PowerPoint will scale down your content to fit the smaller slide size based on the size you selected.

Ensure Fit Issue #1:  Distorted images, slide backgrounds and anything else that PowerPoint had to automatically resize on your slide master.

To fix these issues, you’ll need to navigate to your slide master and adjust (or rebuild) your template to make everything fit.

Ensure Fit Issue #2:  Your content will be scaled down to fit your new slide size, leaving you with a lot of white space. In addition, all your font sizes will be smaller, making them hard to read.

For small content like this, you’ll need to work through your slides and resize your content accordingly. Keep in mind the people at the back of the room too when choosing a new font style and size.

Saving your custom slide size as a PowerPoint theme

If want to use your own custom slide size for all your future PowerPoint presentations, you can save and set it as a PowerPoint theme.

This is a two-step process as discussed below.

1. Save your custom slide size as a theme

To save your custom slide size (and settings) as your own custom PowerPoint theme, simply:

• Open the M ore options
• Click  Save Current Theme
• Name your Theme (and don’t change the file location it saves to)
• Click  Save

2. Set your custom theme as the default

To set a custom PowerPoint theme as the default for all your future presentations, simply:

• Open the  More options
• Right-click  your custom theme
• Select  Set as Default Presentation
• Close out of PowerPoint (and do not save any presentations if it prompts you)

Once you’ve set your own custom theme as the Default Presentation, it will open every time you start PowerPoint. This saves you from always having to switch your slide sizes.

So that’s how you can change your PowerPoint slide size, either before or after you create your presentation.

And although you are given a lot of flexibility in the slide sizes you can choose from, I recommend using the default slide sizes as used by most people.

It’s also important to remember that switching slide sizes after you have built your presentation can be a total pain. So, to the extent possible, figure out your PowerPoint slide size first before you build out your presentation.

How to Adjust Slide Size in PowerPoint: A Quick & Easy Guide

by Enterprise DNA Experts | PowerPoint

Ever started making a presentation in PowerPoint, only to realize that the slides are too small, or too big?

It’s happened to the best of us.

The good news is, adjusting the slide size in PowerPoint is a simple process that can help you avoid this problem and create presentations that look just right.

To adjust the slide size in PowerPoint, click on the “Design” tab, and then “Slide Size.” You can choose from two standard slide sizes, either “Standard (4:3)” or “Widescreen (16:9).” Additionally, you can also choose a custom slide size by entering the dimensions manually.

In this article, we’ll take you through the steps of adjusting the slide size in your presentation.

You’ll also learn about the various options available for slide size, and why it’s important to choose the right one for your presentation.

Let’s get started!

Table of Contents

What is Slide Size in PowerPoint?

Slide size in PowerPoint refers to the dimensions of a single slide in a presentation. It determines the width and height of the slide and can be customized to fit different screen aspect ratios and output formats.

Aspect Ratio: This is the proportional relationship between the width and height of a slide. The two most common aspect ratios for slides are 4:3 (standard) and 16:9 (widescreen).

Remember, the aspect ratio you choose will depend on the intended display or output format of your presentation.

Output Format: The slide size can be adjusted based on the output format you plan to use. For example, if you’re creating a presentation for a standard projector, you might choose a 4:3 aspect ratio.

On the other hand, if your presentation will be displayed on a widescreen TV or uploaded to an online platform, a 16:9 aspect ratio is typically recommended.

By customizing the slide size, you can ensure that your actual presentation looks its best on various devices and platforms.

2 Ways How to Adjust the Slide Size in PowerPoint

There are two ways to adjust the slide size in your presentation: using the default settings or customizing the size to meet your specific needs.

1. How to Adjust Slide Size Using the Default Settings

If you are using PowerPoint 2013 or later, you can adjust the slide size using the default settings.

Here’s how to do it:

Open your PowerPoint presentation.

Click on the “Design” tab in the Ribbon menu.

In the “Customize” group, click “Slide Size.”

Choose either “Standard (4:3)” or “Widescreen (16:9)” from the drop-down menu.

PowerPoint will adjust the slide size according to your selection.

Note: In PowerPoint 2010 and earlier versions, the “Design” tab is called the “Page Layout” tab. The steps are the same.

Now that you’ve learned how to adjust the slide size using the default settings, let’s move on to customizing the size to fit your specific needs .

2. How to Adjust Slide Size by Customizing It

If you have specific slide dimensions in mind for your presentation slides, you can easily customize the slide size in your presentation.

Follow these steps:

Open your presentation.

In the “Customize” group, click “Slide Size” and then select “Custom Slide Size” or “Page Setup”.

In the “Slide Size” dialog box, you can choose from a list of pre-defined slide sizes, including “On-screen Show,” “Letter Paper,” “A4 Paper,” and more. Alternatively, you can enter custom width and height values in the “Width” and “Height” boxes.

Click “OK” to apply your custom size.

Now that you’ve learned how to adjust the slide size in your presentation, let’s take a look at the different options available for slide size.

Options for Slide Size in PowerPoint

When you’re creating a presentation in PowerPoint, you have a few different options for the slide size . You can choose between the standard size (4:3) and the widescreen size (16:9).

Let’s take a closer look at these options and when you might want to use each one.

1. Standard Size (4:3)

The standard size in PowerPoint is a 4:3 aspect ratio. This means that for every 4 units of width, there are 3 units of height. It’s the traditional size for older television screens and projectors.

The 4:3 aspect ratio provides a more square-shaped slide orientation, which can be beneficial for certain types of content, such as:

Printed handouts

Vertical designs

Content intended for older display systems

Certain templates and design layouts

2. Widescreen Size (16:9)

The widescreen slide size in PowerPoint is a 16:9 aspect ratio. This means that for every 16 units of width, there are 9 units of height. It’s the standard size for most modern high-definition displays, including computer monitors, TVs, and projectors.

The 16:9 aspect ratio provides a more rectangular-shaped slide orientation, which can be beneficial for certain types of content, such as:

Video content

Web-based presentations

Screen sharing

Detailed images

Presentations that need to be compatible with a wide range of devices

Now that you’ve learned about the two main options for slide size for your presentation, let’s discuss why it’s important to choose the right one for your presentation.

Why Choose the Right Slide Size in PowerPoint?

Choosing the right slide size is crucial for creating an effective and professional-looking presentation. The size of your slides not only affects the layout and design but also influences how your content is displayed on different screens and devices.

Here are some key reasons why you should carefully consider your slide sizes:

Optimized content layout: The size of your slides will determine how much content can be displayed at once. A larger slide size, such as widescreen (16:9), allows for more space to work with, enabling you to create visually appealing and uncluttered layouts.

Consistency across devices: By selecting one slide size, you can ensure that your presentation will look consistent and well-proportioned when viewed on various devices , including laptops, projectors, and large displays.

Enhanced readability: Larger slides provide more room for text and images, making it easier for your audience to read and understand your content, even from a distance.

Professional appearance: A carefully chosen slide size demonstrates attention to detail and a commitment to delivering a high-quality presentation. It can also help you stand out as a professional and competent presenter.

Now that you understand the importance of choosing the right slide size for your presentation, let’s review the steps you can take to adjust it in your own PowerPoint presentations.

Final Thoughts

Learning how to adjust the slide size in PowerPoint can significantly enhance the quality of your presentations. By understanding the various options available and making the right choice, you can ensure that your content is well-organized, visually appealing, and consistent across different devices and screens.

So, whether you need a standard 4:3 aspect ratio or a widescreen 16:9 format, PowerPoint makes it easy to customize the slide size to meet your specific needs.

Furthermore, this flexibility allows you to create professional and polished presentations that leave a lasting impression on your audience.

So, the next time you start working on a presentation, remember the importance of slide size and use the knowledge you’ve gained here to make the right choice. Happy presenting!

How to Change Slide Size or Dimensions in PowerPoint

Change PowerPoint Slide Size (Widescreen, Standard or Custom)

by Avantix Learning Team | Updated September 7, 2023

Applies to: Microsoft ® PowerPoint ® 2016, 2019, 2021 and 365 (Windows)

You can change the slide size or aspect ratio of a PowerPoint presentation in all versions. The default slide size or dimensions in 2013, 2016, 2019, 2021 or 365 is widescreen (16:9 aspect ratio). You can also enter a custom slide size if you prefer (including entering slide size in pixels). The best time to set slide size is when you first set up your PowerPoint presentation before you add any content. If you change the size later in the process, you may have to deal with distorted pictures and you may also need to adjust the position and size of various objects on slides in Normal View and in the slide master(s) and layouts in Slide Master View.

The most common slide sizes or aspect ratios are typically used as follows:

• Widescreen or 16:9 aspect ratio is frequently used for onscreen presentations using a projector, monitor or a widescreen TV. Older projectors used the standard aspect ratio but most new projectors are designed for widescreen.
• Standard or 4:3 aspect ratio is often used if slides are intended to be printed on letter size paper.

Slide size changes affect the entire presentation. You cannot change slide size for single slides.

You should never change slide size just before running a presentation as you may not be satisfied with the results. If you already have a presentation with images and other content, it's also a good idea to change slide size on a copy of the presentation so you can keep the original deck and slide size.

Note: Some Ribbon tabs may appear with slightly different names if you are working with PowerPoint 365 and have a smaller screen or different display settings. Buttons on the Ribbon may appear as icons only and are also affected by screen size and display settings.

Regardless of the version of PowerPoint you use, you should go through your slides after you change slide size to be sure you are satisfied with the results. Be sure to check the slide master(s) and layouts in Slide Master View as well.

Change slide size to widescreen or standard

To change slide size to widescreen or standard size:

• In Normal View, click the Design tab in the Ribbon.
• Click Slide Size in the Customize group. A drop-down menu appears.
• Select Widescreen, Standard or another option from the drop-down menu. A dialog box appears with options to maximize content or scale to fit (this dialog appears only if you are moving from a larger to a smaller slide size).
• Select the desired option.

Slide Size appears on the Design tab in the Ribbon:

The following dialog box appears in PowerPoint to maximize content or scale to fit only when you change slide size to a smaller size (such as widescreen to standard):

If you select Maximize, the slide content will not be resized when you change to the smaller slide size.

If you select Ensure Fit, PowerPoint will scale your content to fit the smaller slide size.

Change slide size to a custom size

You can use custom slide sizes. Simply choose options from the Slides sized for drop-down menu in the dialog box (such as A4 paper size) or enter custom dimensions.

To change slide size to a custom size:

• Choose Custom Slide Size from the drop-down menu. A dialog box appears.
• Select an option from the Slides sized for drop-down menu or enter the desired slide size in the Height and Width boxes.
• A dialog box appears with options to maximize content or scale to fit (this dialog appears only if you are moving from a larger to a smaller slide size).

Note that the measurement system in PowerPoint dialog boxes is based on your system settings. If you would like to change the measurement system, check out our article on How to Change the Measurement System in PowerPoint.

The following dialog box appears when you select Slide Size and then Custom Slide Size:

You can create posters in PowerPoint by entering a custom slide size such as 36 inches wide by 56 inches high or 91.44 cm wide by 142.24 cm high. The maximum slide size in PowerPoint is 56 inches or 142.24 cm. As a best practice, set the slide size before adding content to the poster.

Many PowerPoint users are not aware that you can enter slide size in pixels (simply enter the measurement with px beside the number). This is useful in a number of situations such as using PowerPoint to create social media posts. If you enter slide size in pixels (such as 200px), when you tab to another box or close the dialog box, PowerPoint changes the pixels to the equivalent in the current measurement system.

Deal with issues when changing slide size

When changing slide size in existing presentations with content, 4 common issues occur:

• Pictures may be distorted as PowerPoint tries to adjust images to fit slide size. Images on slides in Normal View will be affected as well as images on the slide master(s) and layouts. If pictures are distorted, you will need to either manually resize each image or delete them and insert them again.
• Objects such as placeholders and shapes that have been created in PowerPoint are not in the position you'd like. You may need to move objects or reset one or more slides (on the Home tab in the Ribbon, click Reset in the Slides group).
• Extra space is created if you change to a larger slide size. You may need to move or resize objects and adjust the slide master(s) or layouts in Slide Master View.
• If you have changed to a smaller slide size, you may need to increase font size for placeholders and text boxes.

Dimension differences between different slide sizes

In PowerPoint 2013 and later versions, widescreen (16:9) format measurements are different and are set to 13.33 inches wide by 7.5 inches high or 33.867 cm wide by 19.05 cm high. This matches the height of the 4:3 format.

Avoid issues when changing slide size

To avoid issues in PowerPoint related to slide size, you should:

• Try to set slide size as a first step after you create a presentation and before you have entered any content. In 2013 and later versions, the default is widescreen (16:9 aspect ratio).
• If you have changed slide size in a presentation with content, review your slides to be sure you are satisfied with the results. You should also check the slide master(s) and layouts in Slide Master View.
• Never change slide size just before running a presentation as you may not be pleased with the results and you won't have time to fix your slide deck.
• If you have created a presentation with content, make a copy of the presentation first and change slide size on the copy.

Keep in mind that widescreen is normally used for on screen presentations and standard is often used for printed presentations.

Google Slides Dimensions: What Size is Google Slides and How to Change Slide Size?

Slide dimensions can play an important role when displaying information on large screens or according to the type of content on the slide. A large screen would require a widescreen orientation, and you might even need to customize it to fit the screen size. Similarly, some infographics and illustrations require making necessary adjustments to slide orientation to display the content during the presentation correctly. Like PowerPoint, you can also change slide dimensions in Google Slides.

How to Change Slide Size in Google Slides

Google Slides allow setting different slide dimensions according to user needs, including a Standard, Widescreen, or Custom size. To change Google Slide dimensions, go to File > Page Setup .

You can adjust the Google Slides page size from the pop-up menu displayed via Page Setup. The available options include switching to Standard 4:3, Widescreen 16:9, Widescreen 16:10, and a custom slide size. Select the desired slide size and click Apply .

What Size is Google Slides?

If you’re wondering what Google Slides size is right for you, pick a Google Slides resolution that best goes with your screen type. If it’s an old monitor or small screen, you might want to use a Standard orientation, whereas modern monitors or projectors often suit the Widescreen orientation. 

Standard Orientation (4:3)

The Standard 4:3 slide orientation displays content in a smaller size compared to widescreen orientations. This orientation was commonly used in legacy versions of PowerPoint and Google Slides, as projectors and screen monitors did not offer the utility to project a widescreen slide correctly. However, this orientation is still used for smaller slides and screens. Where the slide content might be smaller and better suited to a Standard slide size. This might include pictures, illustrations, tables, and other types of slide content that might appear too stretched on a widescreen slide orientation.

Widescreen (16:9)

The 16:9 widescreen resolution is quite commonly used, and might even be considered the standard size for modern presentations. This is because 16:9 was the replacement for the 4:3 aspect ratio post-2008, as screen sizes and display standards evolved for monitors, projectors, and television channels globally.

Widescreen (16:10)

While 16:10 is not as widely used as 16:9; it is commonly used in tablets and computer monitors. The ratio is closer to the Golden Ratio of 1.618, but the higher manufacturing cost of devices has meant that manufacturers mainly stick to 16:9 for electronic devices.

Custom Orientation

Google Slides also provides a Custom orientation option, where you can also choose to pick the slide size in inches, centimeters, points, or pixels. This option can be useful if you intend to edit the slide orientation according to a specific document, picture, infographic, etc. For example, you can switch to 8.5 x 11 inches for Letter orientation or 8.27 inches for A4 size. Similarly, you can make changes in pixels, points, or centimeters.

When considering how to edit slide size on Google Slides according to your display monitor or presentation requirements, you might want to run a mock presentation with a colleague. If it’s a remote meeting, the slide size would automatically adjust due to the responsive UIs of various devices. However, one orientation or another might appear more convenient for your audience based on your presentation needs. For example, suppose your remote meeting participants are mainly using mobile devices. In that case, you might want to test out a lower resolution, compared to when you are presenting before an audience using a widescreen monitor.

How to Adjust Slide Size in PowerPoint

PowerPoint presentations are an essential tool for many professionals, students, and educators. Whether you’re creating a lecture slideshow, a business pitch, or a graphic design portfolio, the size of your PowerPoint slides is a crucial factor that can greatly affect the quality and effectiveness of your presentation. In this article, we’ll take a deep dive into understanding and adjusting the slide size in PowerPoint, including its benefits, default settings, customization options, tips for choosing the right size for your needs, and common issues and how to fix them.

Table of Contents

Understanding Slide Size in PowerPoint

Slide size refers to the dimensions of your PowerPoint slides, such as width and height. By default, PowerPoint sets your slide size to 10 inches by 7.5 inches, which is a 4:3 aspect ratio. However, there are other aspect ratios and sizes you can select, depending on your needs and preferences.

Aspect ratio is the relationship between the width and height of your slide. A 4:3 aspect ratio means that the width is 4 units for every 3 units of height. This was the standard aspect ratio for television screens and computer monitors for many years. However, with the rise of widescreen displays, 16:9 aspect ratio has become the new default for PowerPoint, as it fits better with modern screens.

It is important to consider the purpose and audience of your presentation when selecting slide size. If you are presenting on a large screen, such as in a conference room or auditorium, you may want to choose a larger slide size to ensure that your content is visible to everyone in the room. On the other hand, if you are presenting on a smaller screen, such as a laptop or tablet, a smaller slide size may be more appropriate to avoid overwhelming your audience with too much information at once.

Another factor to consider when selecting slide size is the amount of content you plan to include on each slide. If you have a lot of text, images, or other media to include, a larger slide size may be necessary to avoid overcrowding and ensure that your content is legible. However, if you have less content or prefer a minimalist approach, a smaller slide size may be more suitable to create a clean and uncluttered presentation.

Benefits of Adjusting Slide Size in PowerPoint

Adjusting your slide size can bring several benefits to your PowerPoint presentations. Firstly, it can help you ensure that your content is visible and readable, regardless of the device or screen your audience uses. The right slide size can also make your presentation more visually appealing, engaging, and professional-looking. Additionally, some content, such as images or videos, may require specific slide sizes to be displayed correctly.

Another benefit of adjusting slide size in PowerPoint is that it can help you save time and effort. By choosing the right slide size from the beginning, you can avoid having to resize and reposition your content later on, which can be a time-consuming and frustrating process. Moreover, if you plan to share your presentation online or via email, adjusting the slide size can help you reduce the file size and make it easier to send and download.

Finally, adjusting slide size can also help you customize your presentation to your audience and purpose. For example, if you are presenting to a large group in a conference room, you may want to use a larger slide size to ensure that everyone can see your content clearly. On the other hand, if you are presenting to a small group on a laptop or tablet, you may want to use a smaller slide size to avoid overwhelming your audience with too much information at once.

Using the Default Slide Size in PowerPoint

If you’re new to PowerPoint or don’t need to customize your slide size, you can use the default settings. To use the default slide size in PowerPoint, open a new presentation and go to the “Design” tab. Click on the “Slide Size” button, then select “Standard (4:3)” or “Widescreen (16:9)” from the options. PowerPoint will apply the default size to all your slides.

It’s important to note that while the default slide size may work for most presentations, there may be instances where you need to customize the size to fit your content. For example, if you’re creating a presentation to be displayed on a large screen, you may want to use a larger slide size to ensure that your content is easily visible. Similarly, if you’re creating a presentation to be viewed on a mobile device, you may want to use a smaller slide size to ensure that your content fits on the screen. In these cases, you can use the “Custom Slide Size” option in PowerPoint to create a slide size that works best for your needs.

Changing Slide Size in PowerPoint: Step-by-Step Guide

If you want to customize your slide size in PowerPoint, follow these steps:

• Open your presentation in PowerPoint.
• Go to the “Design” tab.
• Click on the “Slide Size” button.
• Select “Custom Slide Size” at the bottom of the menu.
• In the “Slide Size” dialog box, enter the width and height of your desired slide size in inches or centimeters. You can also choose from several predefined options, such as “Banner,” “Ledger,” or “A4” size.
• Click “OK” to apply the new slide size to your presentation.

It’s important to note that changing the slide size may affect the layout of your presentation. If you have images or text boxes that are close to the edge of the slide, they may be cut off or resized. Be sure to preview your presentation after changing the slide size to ensure that everything looks the way you want it to.

Additionally, if you plan on sharing your presentation with others, keep in mind that the slide size may not be compatible with their devices or projectors. It’s a good idea to check with your audience beforehand to see if there are any specific requirements or recommendations for slide size.

How to Increase or Decrease Slide Size in PowerPoint

If you’ve already created a presentation and want to change the slide size, you can do so by following these steps:

• In the “Slide Size” dialog box, enter the new width and height of your desired slide size.
• A warning message may appear, informing you that the new slide size may cause some content to be cropped or distorted. Choose the “Maximize” option if you want PowerPoint to adjust the content proportionally to fit the new size, or “Ensure fit” if you want to keep the content as it is and add borders if necessary.

It’s important to note that changing the slide size may affect the overall layout and design of your presentation. If you have images or graphics that are sized specifically for the original slide size, they may appear stretched or distorted when the slide size is changed. It’s a good idea to preview your presentation after changing the slide size to ensure that all content appears as intended.

How to Change the Orientation of Your Slides in PowerPoint

You can also change the orientation of your slides from landscape to portrait or vice versa in PowerPoint:

• In the “Slide Size” dialog box, choose the orientation you want: “Portrait” or “Landscape.”
• Click “OK” to apply the new orientation to your presentation.

Changing the orientation of your slides can be useful when you want to create a presentation that is optimized for a specific screen or device. For example, if you are creating a presentation to be viewed on a mobile device, you may want to use the portrait orientation to make the slides easier to read.

It’s important to note that changing the orientation of your slides may affect the layout of your content. You may need to adjust the size and position of your images, text boxes, and other elements to ensure that they fit properly on the new slide size.

Customizing Slide Size for Different Devices and Screens

If you’re presenting your PowerPoint on different devices or screens, you may need to adjust your slide size accordingly to ensure the best possible viewing experience. For example, if you’re presenting on a large projector screen, you may need a bigger slide size to avoid pixelation or distortion. On the other hand, if you’re presenting on a mobile device, you may need a smaller slide size to fit the screen.

You can customize your slide size for different devices and screens by following these steps:

• Determine the size and aspect ratio of the device or screen you’ll be presenting on.
• Create a new presentation or open your existing one in PowerPoint.
• Enter the width and height that match the device or screen size and aspect ratio you’ve determined.

Tips for Choosing the Right Slide Size for Your Presentation

Choosing the right slide size for your presentation can greatly enhance its impact and effectiveness. Here are some tips to help you choose the best slide size for your needs:

• Consider your audience and how they’ll be viewing your presentation.
• Match your slide size to the device or screen you’ll be presenting on.
• Allow enough space for text, images, and other content, but avoid overcrowding your slides.
• Use a consistent aspect ratio throughout your presentation for a cohesive look.
• Test your presentation on different devices and screens to ensure compatibility and readability.

Common Issues with Slide Size and How to Fix Them in PowerPoint

Despite your best efforts, you may encounter some issues related to slide size when creating or presenting your PowerPoint. Here are some common problems and how to fix them:

• Content is too small or large: Adjust your slide size to ensure that your content is appropriately sized and readable.
• Content is cropped or distorted: Use the “Maximize” or “Ensure fit” option when changing your slide size to avoid cropping or distortion.
• Text or images are pixelated: Ensure that your images and text are high resolution and adjust your slide size accordingly.
• Slides don’t fit the screen: Use the “Scale to Fit” option in the “Slide Show” tab to adjust the size of your presentation to the screen.

By following these tips and guidelines, you can effectively adjust your slide size in PowerPoint to create engaging, professional, and impactful presentations.

How to Change Slide Size in PowerPoint

PowerPoint allows you to change the aspect ratio of your presentation. The widescreen slide size is best when presenting on modern displays with a 16:9 aspect ratio. If you’ll be presenting on an older display with a 4:3 aspect ratio, you’ll want to use the standard slide size instead.

Change the Slide Size

• Click the Design tab.
• Expand the Customize group.

To change the slide orientation, click the Slide Size button and select Custom Slide Size . Change the slide settings and click OK .

• Widescreen : 16:9 ratio is much wider than it is tall and works well for wide, high definition screens.
• Standard : 4:3 ratio is only slightly wider than it is tall and works best for traditional screens.

• Maximize : Crops your content and fills all the available space on the slide.
• Ensure Fit : Scales content down and leaves additional space at the top and bottom of the slide.

The entire presentation is resized to fit the new format.

PowerPoint Slide Size report

The most common PowerPoint slide ratios are "4:3" and "16:9". In previous versions of PowerPoint, the slide size was 4:3, widescreen, and high-definition formats have been adapted for TV and video. The default slide size in new versions of PowerPoint is widescreen (16:9). And the PowerPoint slide size can be changed by the following method.

The PowerPoint slide size also needs to be adjusted to cover the entire screen for different monitors and devices. You can often see some special proportions of slides at the press conference. In this case, [Custom Slide Size] is used. The following post will explain different PowerPoint Slide sizes and change them.

PowerPoint Slide Size Guide

Whether you are preparing your presentation for a class or your work, you should adapt it to the device which will be used for projecting it. Some devices or even laptops can have different sizes, so you will need to change the dimensions of your presentation. To change the size of your presentation slides, on the Design tab, in the Customize group, click the Slide Size button and then choose one of the pre-defined sizes.

Common PowerPoint Slide Sizes

• Standard (4:3) was the default slide size in older versions of Microsoft PowerPoint, like 2003 or 2007. Standard (4:3) slides have a size of 10 x 7.5 inches or 25.4 x 19.05 cm.
• Widescreen (16:9) is the default slide size in Microsoft PowerPoint 2013, 2016, and 365. Widescreen (16:9) slides have a size of 13.33 x 7.5 inches or 33.867 x 19.05 cm.

4:3 is best viewed on a standard computer screen, while the 16:9 is best viewed on a widescreen computer screen or TV. Using the proper dimensions ensures the presentation is scaled suitably not to appear warped. Widescreen is the default in most versions of PowerPoint.

Custom PowerPoint Slide Size

Using a custom PowerPoint slide size is possible if the default 4:3 or 16:9 options are unsuitable. You might choose to use a custom slide size if you are printing full-size PowerPoint slides using a custom page layout, for instance. To do this, select Design > Slide Size > Custom Slide Size to display the "Slide Size" options menu.

• From the Slides sized for the drop-down list, you can choose pre-defined popular sizes, such as Letter Paper (8.5 x11 in), Ledger Paper (11 x 17 in), A3 Paper (297 x 420 mm), etc.
• Enter the custom sizes in the Width and Height fields.
• Choose the slide orientation in the Orientation group.

You can run your slideshow on a computer screen, a television screen, or a projector. It is best to know your display device upfront. It would be best to change your slide dimensions before designing your slides before adding shapes and images to slides. Changing the dimensions afterward is possible, but it can ruin your slide design. If pictures are distorted, you will need to manually resize each image or delete them and insert them again.

How to Change the Slide Size in Google Slides

When you’re using projectors and monitors to give your presentation, it might not be well-suited for these kinds of screens. However, Google Slides allows you to change the aspect ratio of your presentations , choosing between 16:9 (widescreen), 16:10, 4:3 (standard) and custom.  Depending on where you’re going to give your presentation, you might need an adapted version for widescreen or another one for 4:3 screens. In this tutorial, you’ll learn how to change the aspect ratio step by step.  Have in mind that after modifying the original aspect ratio of your presentation, any elements and images will get scrambled and you’ll need to readjust them one by one in the slides or even the master slides.  To change the aspect ratio of your slides, click on File → Page setup… Then choose the desired option. 

If you need any other size, choose “Custom” and enter the desired width and height values.

For further information on how to change the aspect ratio of your presentation in Google Slides, please refer to this article of the Google Docs support page. Stay tuned for our next Slidesgo School tutorials. See you soon!

Determining the Size of a PowerPoint Slide in Pixels: A Guide

Have you ever wondered what the size of your PowerPoint slide is in pixels? It’s actually pretty simple to figure out, and you can do it with just a few clicks. In this article, I’ll walk you through the steps so you can determine the pixel dimensions of your presentation slides.

Step by Step Tutorial: Determining the Size of a PowerPoint Slide in Pixels

Before we dive into the steps, let’s understand why this is important. Knowing the pixel size of your slides can help you design better presentations that look great on any screen. Plus, if you’re creating content for the web or digital platforms, pixel dimensions are crucial for ensuring your work displays correctly.

Step 1: Open PowerPoint and go to the ‘Design’ tab

Click on the ‘Design’ tab located at the top of the PowerPoint window.

When you’re working on your PowerPoint presentation, the Design tab is where you’ll find all the options for customizing the look and feel of your slides. It’s the gateway to adjusting the size of your slides.

Step 2: Click on ‘Slide Size’

Look for the ‘Slide Size’ button on the right-hand side of the toolbar and click on it.

The ‘Slide Size’ button gives you access to various options for adjusting the size of your PowerPoint slides, including the ability to see and change the pixel dimensions.

Step 3: Select ‘Custom Slide Size’

In the drop-down menu that appears, select ‘Custom Slide Size’ to open the Slide Size dialog box.

The ‘Custom Slide Size’ option allows you to specify the exact dimensions for your slides, including width and height, in various units of measurement including pixels.

Step 4: Check the pixel dimensions

In the Slide Size dialog box, look for the width and height measurements in pixels.

The Slide Size dialog box will show the current size of your slides. If it’s set to a different unit of measurement, you can easily switch to pixels.

Step 5: Adjust the slide size if necessary

If you need to adjust the size of your slides, enter the desired dimensions in pixels and click ‘OK’.

You can customize the size of your PowerPoint slides to fit specific requirements or to ensure that your presentation looks its best on different devices or resolutions.

Once you’ve completed these steps, you’ll have successfully determined the pixel size of your PowerPoint slides. This information can be incredibly useful for graphic design purposes, ensuring that your presentation looks sharp and professional on any screen.

• Standard 4:3 - Choose this aspect ratio if you plan to print out your slides or if someone will view them on a mobile device.
• Widescreen 16:9 - This is the default setting and should be used when viewing on a widescreen.
• Widescreen 16:10 - This is another option for when viewing on a widescreen.
• Custom - Choose this if you need to select a size that isn't displayed in the list of presets.

Click the size you want from the list.

If you choose "Custom," you can enter the width (first box) and height (second box) of the slides. You can also choose which unit of measurement to choose from, with inches, centimeters, points, and pixels being your options.

Regardless if you choose a preset option or set your own custom size, click "Apply" when you're ready to reflect the change to your slides.

That's all there is to it.

This guide teaches you how to change the size of the slides in your Google Slides presentation on a browser to ensure you use the correct size.

How to resize your Google Slides on a Chromebook

You're likely sticking to Google's ecosystem while working on a Chromebook. Google Slides becomes an essential tool when building a presentation. Google Slides works like the Windows computer version, so changing the slides' size is simple. Here's how to do it:

• On a Chromebook, open Google Slides on a Chrome tab.
• Start a new presentation or open an existing one by going to File > Open .
• Click File > Page setup .
• In the Page setup window, select the drop-down box and choose Standard 4:3 , Widescreen 16:9 , Widescreen 16:10 , or Custom .

How to expand the size of your Google Slides presentation

Sometimes, presentations can start in the wrong view. Fullscreen mode ensures the set aspect ratio of the slideshow remains the same on the screen. However, the audience may see another view if you select the wrong mode before starting your presentation. The view you can accidentally click is Presenter View.

Inside Presenter View, the audience sees a fullscreen presentation of your Google Slides (if presented on a different screen), while you see the speaker notes written below the slides and some settings. Seeing a busier screen can distract the speaker, especially if the slides remain in autoplay . As a result, you may prefer to set up fullscreen mode. Below are the steps to ensure your Google Slides start in fullscreen mode.

How to enter fullscreen mode on Google Slides

• Open a saved Google Slides presentation on your computer.
• Click the arrow at the bottom of the Slideshow button and select Start from beginning .

Clicking the Slideshow button also puts your presentation in fullscreen mode.

How to resize your Google Slides on mobile

The slide size in Google Slides on the Android and iOS mobile apps cannot be manually changed. To get around this, open Google Slides on a computer and follow the steps above to adjust the size of your slides.
