Question details

PowerPoint continues to display shape sizes and text-box margins in inches despite macOS metric settings, and new margin values revert to zero.

Product
Microsoft PowerPoint for Mac
Device & OS
macOS Sequoia 15.1
Scenario
Attempting to adjust text-box margins or shape sizes using metric measurements in PowerPoint.
Observed behavior
Measurements remain stuck in inches, and newly entered margin values either become zero or have no effect on the presentation.
Before you start

Ensure all your ongoing PowerPoint presentations are saved and completely closed before resetting application preferences or restarting your Mac.

Solution 1Recommended

Reset PowerPoint Preferences

Use this method to clear corrupted preference files that may be forcing PowerPoint to ignore your macOS metric settings.

PowerPoint relies on hidden preference files to maintain user settings. When these files become corrupted or face compatibility issues after a macOS update, the application might default to standard imperial units (inches) regardless of your system's region settings.

1
Quit Office Applications

Ensure that Microsoft PowerPoint and all other Office applications are completely closed on your Mac.

2
Move Preference Files

Navigate to your hidden user Library folder and locate the PowerPoint preference files (usually under ~/Library/Containers/com.microsoft.Powerpoint/). Move these files to your desktop as a backup.

3
Restart and Test

Restart your Mac. Open PowerPoint, create a new presentation, and check if the text box margins and shape sizes now correctly display and accept metric values.

Reset PowerPoint Preferences
Data Safety: Moving preference files will not delete your saved presentations. If the issue is not resolved, you can restore the files from your desktop to their original location.

Frequently Asked Questions

Why are my PowerPoint measurements in inches when my Mac is set to metric?

PowerPoint relies on your macOS system region settings for measurement units. However, preference file corruption or specific compatibility bugs in macOS Sequoia can cause the application to ignore these system settings and default back to inches.

Where are the PowerPoint preference files located on Mac?

PowerPoint preference files are typically stored in the hidden Library folder. You can usually find them by navigating to ~/Library/Containers/com.microsoft.Powerpoint/ via the 'Go to Folder' option in Finder.

Will resetting my PowerPoint preferences delete my presentations?

No, resetting the preference files only restores the application's default interface and functional settings. It does not delete, move, or alter any of your saved presentation files.
