How to Fix Missing Custom Slide Size in PowerPoint for Android
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.
Before you start

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.

Solution 1Recommended

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.

1
Open Desktop PowerPoint

Launch Microsoft PowerPoint on your Windows PC or Mac and open the presentation you want to modify, or create a new blank presentation.

2
Navigate to the Design Tab

Click on the 'Design' tab located in the top ribbon menu.

3
Set Custom Dimensions

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'.

4
Save to Cloud Storage

Save the presentation to a cloud service accessible on your mobile device, such as OneDrive or Google Drive.

5
Open on Android

Launch PowerPoint on your Android device and open the synced file. The presentation will load while preserving your custom slide dimensions.

Frequently Asked Questions

Does PowerPoint for iOS have the custom slide size option?

No. The iPhone and iPad versions of Microsoft Office share the same limitations as the Android version and do not offer a custom slide-size option. You will only see the Standard and Widescreen options.

Will my custom slide size be lost if I edit the file on Android?

No. While you cannot create or change custom dimensions within the Android app, PowerPoint for Android will safely preserve the existing custom dimensions when you open and edit the presentation.

Can I use PowerPoint for Web to change the slide size to custom dimensions?

No. PowerPoint for the Web also provides a limited feature set compared to the desktop version and does not currently support creating custom slide sizes.
