Remove or Disable Duplicate Arial Font Versions

Identify and disable conflicting PostScript and TrueType Arial font formats using your font manager or macOS Font Book.

Having multiple versions of the same font (like PostScript and TrueType) installed simultaneously can confuse Word's rendering engine, leading to unpredictable line spacing. Disabling the duplicate versions forces Word to use the standard system font.

1
Open your font manager

Launch macOS Font Book or your third-party font manager (such as RightFont) from your Applications folder.

2
Search for Arial

Type 'Arial' into the search bar to display all installed versions of the font on your system.

3
Identify duplicate formats

Look for duplicate entries of Arial Regular. Check the font information to see if both TrueType (TTF) and PostScript versions are active.

4
Disable the duplicate font

Select the duplicate or older PostScript version, right-click it, and choose 'Disable' or 'Remove'.

5
Restart Microsoft Word

Completely quit Microsoft Word and open it again. Check your document to verify that the Arial line spacing is now rendering correctly.

Remove or Disable Duplicate Arial Font Versions
Clear Font Cache: If the spacing issue persists after disabling the font, you may need to clear your Mac's font cache. You can do this by restarting your Mac in Safe Mode (holding down the Shift key during startup) and then restarting normally.

Frequently Asked Questions

Why does Arial look different in Word for Mac compared to other applications?

Word for Mac uses its own proprietary text rendering engine rather than relying entirely on the native macOS Core Text. This engine can sometimes misinterpret line height metrics when multiple formats (like PostScript and TrueType) of the same font are active simultaneously.

Can a third-party font manager cause line spacing issues in Word?

Yes. Tools like RightFont or Suitcase Fusion can sometimes activate legacy PostScript fonts that conflict with the system's default TrueType fonts, leading to erratic formatting behavior like excessive line spacing in Microsoft Word.

How do I know if a font is TrueType or PostScript on a Mac?

You can open the macOS Font Book, select the font in question, and click the 'Information' (i) button in the toolbar. The panel will display the font format, indicating whether it is TrueType, OpenType, or PostScript.
