Can I change the size of my slides?

It's not possible to change the size of your slides in PowerPoint Online. By default, presentations you create in PowerPoint Online are in wide screen format. However, if you have desktop PowerPoint, click Open in PowerPoint and change the slide size to Wide screen (16:9), Standard (4:3), or a custom size.

Widescreen and Standard sized slides

Follow the steps in Change the size of your slides.

When you save the presentation in PowerPoint, you'll see the new slide size the next time you open the presentation in PowerPoint Online.

If you don't have the desktop version of PowerPoint, you can try or buy the latest version now.

Tip: We're continually updating PowerPoint Online based on input like yours. Tell us how we could improve this feature for you. At the bottom of the PowerPoint Online window, click Help Improve Office.
