Fix Missing Custom Slide Size in PowerPoint for Android
Question details
The user is trying to set a custom slide size in PowerPoint for Android but cannot find the feature.

- Product
- Microsoft PowerPoint
- Device & OS
- Android
- Scenario
- Creating or modifying a presentation on an Android tablet or smartphone to have specific slide dimensions.
- Observed behavior
- PowerPoint for Android only provides Standard (4:3) and Widescreen (16:9) slide sizes. The Custom Slide Size command is completely missing.
Ensure you have access to a desktop or laptop computer with the full desktop version of Microsoft PowerPoint installed, as this workaround requires desktop software.
Use Desktop PowerPoint to Set Custom Slide Size
Since the mobile version lacks the feature, you must create and size your presentation on a desktop, then open it on your Android device.
Mobile and web versions of Microsoft Office provide fewer features than their full desktop counterparts. While PowerPoint for Android cannot initiate a custom slide size, it is capable of preserving custom dimensions if the file is created elsewhere.
Launch Microsoft PowerPoint on your Windows PC or Mac and open the presentation you want to modify, or create a new blank presentation.
Click on the 'Design' tab located in the top ribbon menu.
Click 'Slide Size' on the far right of the ribbon, then select 'Custom Slide Size'. Enter your desired width and height dimensions, and click 'OK'.
Save the presentation to a cloud service accessible on your mobile device, such as OneDrive or Google Drive.
Launch PowerPoint on your Android device and open the synced file. The presentation will load while preserving your custom slide dimensions.

Try WPS Office for Seamless Mobile Presentations
Mobile versions of Microsoft Office often lack advanced features found on desktop. WPS Office offers a free, lightweight, and highly compatible alternative for viewing and editing presentations on Android and iOS devices, ensuring your custom layouts are preserved perfectly.
- 1. Download WPS Office: Install WPS Office for free from the Google Play Store on your Android device.
- 2. Open Your Presentation: Launch the app and open your PPTX file directly from your local storage or cloud drive.
- 3. Edit with Precision: Edit your slides seamlessly while ensuring all original custom dimensions and complex layouts remain intact.
