Update OneNote and Check the Draw Tab

The most common reason for missing features is an outdated app version or looking in the wrong menu tab.

Microsoft frequently updates the OneNote app for iPadOS to add features or fix bugs. If the ruler is missing, updating to the latest version and ensuring you are in the correct drawing mode is the first step.

1
Check for Updates

Open the App Store on your iPad, search for Microsoft OneNote, and tap 'Update' if a newer version is available.

2
Open a Notebook Page

Launch the OneNote app and navigate to the specific notebook page where you want to draw.

3
Access the Draw Tab

Tap the 'Draw' tab located at the top menu ribbon of the screen.

4
Activate the Ruler

Look for the 'Ruler' icon among the drawing tools (usually next to the pens and eraser) and tap it to activate it on your screen.
