How to Fix Very Small Fonts in OneNote for Windows
Question details
Users are experiencing unusually small font sizes in the OneNote title-page section, specifically affecting Thai and English text after a software update.

- Product
- Microsoft OneNote
- Device & OS
- Windows 10, Windows 11
- Scenario
- Typing or viewing notes in the title-page section of OneNote after a recent Windows or Office software update.
- Observed behavior
- Text renders much smaller than intended. Reinstalling the application or changing keyboard layouts does not resolve the issue.
Ensure your device has an active internet connection to check for system updates, and verify that you have synced any unsaved notes before making system-level display changes.
Install Updates and Adjust Windows Display Scaling
Updating Windows and adjusting your system's display scaling can fix underlying rendering bugs that cause text to appear too small.
This issue is often caused by a rendering conflict introduced in specific builds (such as build 17628.20144). Installing the latest patches and adjusting system-wide text sizes can act as an immediate workaround.
Open Windows Settings, go to Update & Security (or Windows Update in Windows 11), and install all available system and Microsoft Office updates.
Right-click on your desktop, select 'Display settings', and look for the 'Scale and layout' section. Try temporarily increasing the scale percentage to 125% or 150%.
In Windows Settings, navigate to Accessibility > Text size, and adjust the slider to make text slightly larger, then click Apply.

Test with a Standard Font
Certain localized fonts might have rendering issues after an update. Switching to a universally standard font can bypass the bug.
Submit Feedback to Microsoft Support
Reporting known rendering bugs helps Microsoft identify the affected builds and release a permanent patch.

Frequently Asked Questions
Why is my text suddenly so small in OneNote?
This usually occurs due to a rendering bug introduced in a recent Office or Windows update, or an issue with how specific localized fonts interact with the application's display scaling.
Will reinstalling OneNote fix the font rendering issue?
In many cases involving application rendering bugs, uninstalling and reinstalling the software does not resolve the issue, as the bug resides in the current build version or your system-level display settings.
How do I change the default font in OneNote for Windows?
To change the default font, click on File, then select Options. Under the General tab, look for the 'Default font' section, select your preferred font (like Tahoma), adjust the size, and click OK.
Can Windows display scaling affect only one application?
Generally, Windows display scaling affects all applications. However, certain apps might misinterpret these scaling settings after a software update, causing text to render incorrectly compared to other programs.
