How to Reduce an Oversized Ribbon in Microsoft 365 Outlook and Excel

Product: Microsoft 365 (Outlook, Excel)
Device & OS: not provided
Scenario: Using Outlook and Excel for daily tasks but finding the interface elements disproportionately large.
Observed behavior: The ribbon menu in Microsoft 365 applications appears oversized, while document contents like email text and spreadsheet cells remain at a normal font size.

Before you start

Ensure your computer's general display scaling settings are set to the recommended percentage before troubleshooting specific Office application interfaces.

Solution 1Recommended

Toggle Touch/Mouse Mode in the Quick Access Toolbar

Office applications automatically switch to 'Touch Mode' on touch-enabled devices, which enlarges the ribbon. Switching back to 'Mouse Mode' usually fixes the issue.

Touch Mode spaces out the buttons on the ribbon so they are easier to tap on a touchscreen device. If you are using a standard mouse and keyboard, disabling this mode will restore the ribbon to its normal, compact size.

Customize the Quick Access Toolbar

Open Excel or Outlook and click the drop-down arrow at the top-left corner of the window to open the Quick Access Toolbar menu.

Add Touch/Mouse Mode Command

Select 'Touch/Mouse Mode' from the drop-down list to add its icon to your toolbar.

Switch to Mouse Mode

Click the newly added hand icon on the toolbar and select 'Mouse' to optimize the interface spacing for a standard mouse.

Solution 2

Check System Display and Scaling Settings

If switching modes doesn't work, system-wide display scaling might be forcing large UI elements across all applications.

Frequently Asked Questions

Why did my Excel ribbon suddenly get so big?

This usually happens if you are using a touch-enabled laptop or monitor. Office automatically activates 'Touch Mode', which spaces out buttons to make them easier to tap with your fingers.

Can I hide the ribbon entirely to save screen space?

Yes. You can double-click any ribbon tab (like Home or Insert) to collapse it. The ribbon will temporarily drop down when you click a tab and hide again when you click back into your document.

Does reinstalling Office fix the oversized ribbon issue?

Often, reinstalling or running Office in Safe Mode does not fix this specific UI scaling issue, as it is usually tied to user profile settings, Touch Mode preferences, or Windows display scaling rather than corrupted software.
