Fonts on File Explorer suddenly 50% smaller

Question

Several days ago, the fonts on File Explorer and the bookmarks for all of the browsers I use (Chrome, Brave, Firefox) shrunk by 50% without anything else changing.

I tried changing the text size under Accessibility. This makes the text that had shrunk a bit larger while making all the other fonts gigantic.

I had made NO changes to anything before this happened.

Hi James Alias,

Thanks for reaching out to Microsoft Q&A Forum. I understand that the fonts in File Explorer and browser UI (bookmarks and menus) suddenly became much smaller without any intentional changes, and adjusting Text size causes other UI elements to become excessively large.

Please make sure you already tried the Q&A Assist steps. In addition, please try the following.

To help narrow this down, I’d like to check a couple of details first:

1. Are you using more than one display, or did you recently disconnect an external monitor or docking station?
2. Is the screen resolution currently set to the recommended value for your display?

In the meantime, you can try these steps:

1, Check for custom scaling

• Open Settings
• Go to System then Display
• Under Scale, select Advanced scaling settings
• If a custom scaling value is set, clear it and sign out when prompted

2, Verify display resolution and refresh rate

• Open Settings
• Go to System then Display
• Confirm Display resolution shows Recommended
• Select Advanced display and confirm the refresh rate matches the panel’s native rate

3, Reapply ClearType text tuning

• Open Start and search for ClearType
• Select Adjust ClearType text
• Turn ClearType off, finish the wizard, then turn it back on and complete the tuning

4, Check DPI compatibility for Explorer-related processes

• Open Task Manager
• Restart Windows Explorer
• Sign out and sign back in to force DPI recalculation

5, Update or roll back the display driver

• Open Device Manager
• Expand Display adapters
• Right-click the active adapter and select Update driver
• If the issue started after a recent update, select Properties, then Driver, and choose Roll Back Driver if available

6, Test with a temporary new user profile

• Create a new local user account
• Sign in to that account and check whether the font size behavior is the same

Answer 2

This is not a reported problem after any recent update.

Open the Settings App, then go to Windows Updates - Update History.

What is the KB number of the latest update installed, is it the KB5077241 optional preview update.

Use Windows’ display scaling rather than only the text-size slider so that File Explorer and browser UI text scale consistently without making other text excessively large.

Try these steps in order:

1. Reset text size
   1. Select Start > Settings > Accessibility > Text size.
   2. Move the Text size slider back to 100% (or the default) and select Apply.
2. Adjust overall scale for apps and system UI
   1. Select Start > Settings > System > Display.
   2. Under Scale (or Scale & layout), choose a larger percentage (for example, 125% or 150%).
   3. Sign out and sign back in if prompted so File Explorer and browser chrome (tabs, bookmarks, menus) pick up the new scaling.
3. If text is still too small, use Magnifier for targeted zoom
   1. Press Windows logo key + Plus (+) to turn on Magnifier and zoom in.
   2. Press Windows logo key + Plus (+) again to zoom further.
   3. Press Windows logo key + Minus (-) to zoom out.
   4. Press Windows logo key + Esc to turn Magnifier off.

These options enlarge File Explorer and browser UI elements together, instead of only increasing some text while leaving other fonts tiny or making unrelated text extremely large.
