How to Increase Font Size in Microsoft Office Dialog Boxes
Product
Microsoft Office
Device & OS
Windows
Scenario
Attempting to improve readability within legacy dialog menus, such as the Edit Hyperlink window in Excel, where text remains too small despite general display scaling.
Observed behavior
Windows display scaling successfully enlarges the main application ribbon and document text, but the font size inside certain Office dialog boxes remains unchanged.
Before you start

Save your work and close any active dialog boxes in your Office applications, as applying system-wide text scaling will cause Windows to temporarily refresh your screen.

Solution 1Recommended

Adjust Windows Text Size Settings

Modify the system-wide text scaling settings in Windows to force Microsoft Office dialog boxes to display larger fonts.

Because some Microsoft Office dialog boxes rely on older user interface frameworks, they do not always respond to the standard percentage-based display scaling used for monitors. Instead, they pull their font sizes from the core Windows accessibility settings.

1
Search for Text Size Settings

Click the Windows Start button or press the Windows key on your keyboard. In the search bar, type 'Make text size bigger'.

2
Open Accessibility Menu

Click on the matching result to open the Vision or Accessibility settings menu directly to the Text size section.

3
Adjust the Text Size Slider

Locate the Text size slider on the screen. Click and drag the slider to the right until the preview text above it reaches a comfortable size for reading.

4
Apply the Changes

Click the 'Apply' button next to the slider. Your screen will briefly display a 'Please wait' message as Windows updates the font sizes across your system and applications.

Frequently Asked Questions

Why does standard Windows display scaling not affect Office dialog boxes?

Standard display scaling enlarges modern applications and primary interfaces like the Office ribbon. However, certain dialog boxes (like Edit Hyperlink) use older programming frameworks that only respond to the system's absolute text size parameter rather than overall display percentages.

Will increasing the text size affect other programs on my computer?

Yes. Adjusting the 'Make text size bigger' slider in Windows is a system-wide setting. It will increase the font size in File Explorer, system menus, and most other installed applications.

Can I change the font size for a specific Office app like Excel only?

No, Microsoft Office does not offer a built-in setting to independently adjust the text size of its dialog boxes. It relies entirely on your global Windows accessibility settings.
