Question details

Users operating a 2-in-1 device in portrait mode notice that the OneNote floating pen toolbar displays fewer pen options than it does in landscape mode.

How to Show More Pens in the OneNote Floating Toolbar in Portrait Mode
Product
Microsoft OneNote
Device & OS
2-in-1 computer
Scenario
Using the OneNote application for drawing or taking handwritten notes while the device screen is rotated to portrait orientation.
Observed behavior
The floating toolbar automatically shrinks and reduces the number of visible pens, with no available setting to manually increase the pen count.
Before you start

Verify that your OneNote application is updated to the latest version, though keep in mind that the toolbar's dynamic resizing is a default design behavior rather than a software bug.

Solution 1Recommended

Reorganize Pens and Utilize Landscape Mode

Since you cannot increase the total number of pens displayed in portrait mode, prioritize your most used pens or switch screen orientations for full access.

OneNote's interface dynamically adapts based on the available screen width. Because portrait mode is narrower, the toolbar shrinks to prevent overlapping with other UI elements.

1
Prioritize your preferred pens

Open OneNote in landscape mode where all pens are visible. Reorder your most frequently used pens to the first few slots so they remain visible when the toolbar inevitably shrinks in portrait mode.

2
Rotate to landscape for full access

When you need immediate access to your complete collection of pens and highlighters, physically rotate your 2-in-1 device back to landscape orientation.

Reorganize Pens and Utilize Landscape Mode
Auto-adjustment Limitation: There is currently no built-in setting in Microsoft OneNote to disable this auto-adjustment or manually set the number of visible pens.

Frequently Asked Questions

Can I manually resize the floating toolbar in OneNote?

No, OneNote does not provide an option to manually resize the floating toolbar. It automatically adjusts based on your device's screen size, notebook page, and orientation.

Why do some pens disappear when I rotate my tablet?

When you rotate your device to portrait mode, the screen becomes narrower. OneNote compensates by shrinking the toolbar, which hides some of the pens to fit the smaller width without overlapping other menus.

Are there third-party add-ins to fix the OneNote toolbar in portrait mode?

Currently, popular third-party tools and macros do not have the ability to override OneNote's core UI behavior regarding the responsive design of the floating pen toolbar.
