Disable Autofit via PowerPoint Desktop Application

Since PowerPoint for the web does not support disabling Autofit directly, opening the file in the desktop version is the most reliable method to change this setting.

The web version of PowerPoint lacks the specific 'Format Shape' text options required to turn off automatic resizing. By opening your presentation in the desktop application, you can easily disable the Autofit behavior, and the changes will sync back to your web document.

1
Open in Desktop App

In PowerPoint Online, click the 'Viewing' or 'Editing' button at the top ribbon and select 'Open in Desktop App'.

2
Access Format Shape Options

Once opened in the desktop application, right-click the affected shape or text box and select 'Format Shape' from the context menu.

3
Navigate to Text Options

In the Format Shape pane that appears on the right, click on 'Text Options' and then select the Text Box icon.

4
Select Do Not Autofit

Under the Autofit settings, choose the 'Do not Autofit' option. Save your presentation to sync the formatting changes back to PowerPoint Online.

Mac Users: If you are using a Mac, you can access these settings by selecting the shape, clicking 'Format' in the top menu, choosing 'Format Object', and then navigating to 'Text Options'.

Frequently Asked Questions

Why does PowerPoint Online shrink my rectangles when I type?

PowerPoint uses an 'Autofit' feature that automatically adjusts the size of text boxes and shapes to fit the text inside them. In PowerPoint Online, this behavior is often enabled by default to prevent text from overflowing.

Can I disable Autofit directly in PowerPoint for the web?

Currently, PowerPoint for the web does not provide a direct menu setting to turn off automatic text fitting. You need to use the desktop application to access these specific text options or use manual workarounds.

Will disabling Autofit in the desktop app carry over to the web version?

Yes. If you open your presentation in the desktop app, set the shape to 'Do not Autofit,' and save it, the web version will respect this formatting rule and stop resizing the affected shape.

How do I access text options on PowerPoint for Mac?

On a Mac device, select the shape, go to the 'Format' menu at the top of the screen, choose 'Format Object', and then navigate to the 'Text Options' tab to find and modify the Autofit settings.
