How to Change the Size of a PowerPoint Slide

Go to the Design tab. Click Slide Size in the Customize section of the ribbon. Choose Custom Slide Size on Windows or PowerPoint on the web or Page Setup on Mac . Use the Slides sized for a drop-down box to select a size closest to the measurements you need, or select Custom to input your own.

PowerPoint is a powerful tool that helps you create professional presentations with ease. However, one of the most common issues that users face is changing the size of their slides. In this post, we’ll walk you through the process of changing the size of a PowerPoint slide.

To begin, you need to find the page setup option. You can do this by going to the File dropdown and selecting Page Setup or by looking for the Slide Size icon on the Design tab. Once you click on it, you will see two options – presets or custom.

If you want to create a custom size, you can easily do so by editing the height and width of your slide. For instance, if you want your presentation to be printed on an 8.5 by 11-inch paper, you can change the width and height accordingly. You can also adjust the orientation of your slide here. Moreover, you can customize your header and footer layout.

If you want to change the size of your slide in pixels, you can input the desired dimensions. For example, if you’re designing a social media post, you might want your slide to be 1080 by 1080 pixels. You can input those values, and PowerPoint will convert them to the relevant unit of measurement.

Once you have set your preferred dimensions, click on OK. You might see a warning message that says you’re converting to a larger slide size, asking if you want to scale your content up. If you click on scale, your content will be scaled up, and you will see the difference in the boxes. However, scaling up images and other visual elements might not work out for you. In this case, you can undo the scaling with the Command or Control Z keys and choose to scale your content up or down as per your preference.

In conclusion, changing the size of a PowerPoint slide can be a useful tool to create customized presentations. By following these steps, you can easily adjust the size of your slides to fit your specific needs.


How do you change the size of a slide in PowerPoint without scaling content?
Click on the Slide Size drop-down menu and select either the Standard(4:3) or Widescreen(16:9) aspect ratios and select the 'Ensure Fit' option (it is easier to move items around than to also have to resize them especially when converting to a larger slide size).
What size is a 16:9 PowerPoint slide pixels?
See the example above: In this example, going from left to right you see the 4:3 (usually 1024 pixels wide x 768 high) ratio screen size and on the right the 16:9 (usually 1920 pixels wide x 1080 pixels high) ration screen size.
