How to Fix Unusually Large OneNote Notebook and Page Tabs
Question details
Users need a way to reduce the size of notebook, section, and page tabs in OneNote when they become excessively large.

- Product
- Microsoft OneNote
- Device & OS
- Windows 10, Windows 11
- Scenario
- Following a recent Windows or Microsoft Office update, the OneNote user interface tabs become oversized, impacting workspace visibility.
- Observed behavior
- OneNote notebook, section, and page tabs appear abnormally large. The application lacks independent controls to adjust the font or tab sizes, making it difficult to navigate.
Before modifying system display settings or performing updates, ensure all your open OneNote notebooks are fully synced to OneDrive to prevent any accidental data loss.
Adjust Windows Display Scaling and Accessibility Settings
Since OneNote relies on Windows system settings for its interface rendering, adjusting the system-wide text size and display scaling often resolves oversized tabs.
OneNote does not have built-in font size controls for its navigation menus. It scales directly with your Windows display preferences.
Right-click on an empty area of your Windows desktop and select 'Display settings' from the context menu.
Scroll to the 'Scale and layout' section. Ensure the scaling dropdown menu is set to the 'Recommended' percentage (usually 100% or 125%).
Navigate to Settings > Accessibility > Text size. If the text size slider has been increased, drag it back to the left (minimum size) and click the 'Apply' button.
Close Microsoft OneNote completely and reopen it to see if the interface tabs have returned to their normal size.

Install the Latest Windows and Office Updates
Microsoft frequently releases patches to address user-interface regressions or display bugs caused by previous flawed updates.
Test with a New Notebook and Report the Bug
If the issue persists despite adjusting scaling and updating, it is likely a known Microsoft user-interface bug that requires a developer patch.

Frequently Asked Questions
Can I change the font size of just the tabs in OneNote?
No, OneNote currently does not offer independent settings to change the font size of specific UI elements like notebook, section, or page tabs. These elements scale automatically with your Windows system display and accessibility settings.
Why did my OneNote interface change suddenly?
Microsoft updates Office and Windows frequently. These background updates can sometimes alter user-interface elements, such as tab sizes, ribbon layouts, and menu locations, resulting in unintended or oversized display changes.
Will reinstalling Office fix the oversized tabs?
Reinstalling Office rarely resolves UI regression bugs introduced by updates. It is generally more effective to adjust your Windows display scaling settings or wait for a subsequent bug-fix patch from Microsoft.
