Fix Apple Pencil Writing Too Thick in OneNote on iPad
Question details
The user needs to fix an issue where their Apple Pencil handwriting randomly becomes excessively thick when taking notes.

- Product
- Microsoft OneNote
- Device & OS
- iPadOS
- Scenario
- Taking handwritten notes using an Apple Pencil in the Microsoft OneNote app for iPad.
- Observed behavior
- The Apple Pencil strokes randomly become much thicker than intended, despite the pencil working normally in Microsoft Word and other applications. Reinstalling the app and restarting the iPad do not resolve the issue.
Ensure your Apple Pencil is fully charged and the tip is securely tightened, as hardware looseness can occasionally cause erratic pressure sensitivity readings.
Update OneNote and iPadOS to the Latest Version
Software glitches causing Apple Pencil pressure sensitivity issues are often patched in application or system updates.
Many users experience this specific glitch on older builds, such as OneNote version 16.49 and iPadOS 14.6. Updating both the app and the operating system often provides a permanent fix for digital ink inconsistencies.
Launch the App Store on your iPad and tap your profile icon at the top right corner of the screen.
Scroll down to view pending updates. If Microsoft OneNote is listed, tap 'Update' next to it to install the latest version.
Go to your iPad Settings, navigate to 'General' > 'Software Update', and install any available system updates.

Submit Feedback to Request a Pressure Sensitivity Toggle
Since OneNote currently lacks a native setting to disable pressure sensitivity on iPad, submitting direct feedback can encourage Microsoft to add this feature.
Perform a Factory Reset or Contact Apple Support
If software updates fail to resolve the problem, resetting the device can clear deep-rooted system conflicts affecting the Apple Pencil digitizer.
Try WPS Office for Seamless Document Annotation and Note-Taking
If Microsoft OneNote continues to have handwriting issues on your iPad, consider switching to WPS Office. It provides a highly compatible, lightweight environment for reading, annotating PDFs, and managing your documents effortlessly without frustrating pressure sensitivity glitches.
- 1. Install WPS Office: Download and install WPS Office for free from the iPad App Store.
- 2. Open or Create a Document: Launch the app and tap the '+' icon to create a new document, or open any existing Microsoft Office file or PDF.
- 3. Use Stable Drawing Tools: Navigate to the 'Draw' tab to access smooth, optimized Apple Pencil tools for taking notes and highlighting text without random thickness glitches.

Frequently Asked Questions
Can I turn off Apple Pencil pressure sensitivity in OneNote for iPad?
Currently, Microsoft OneNote for iPad does not have a built-in setting to disable pressure sensitivity for the Apple Pencil. You can submit feedback through the app's settings menu to request this feature in future updates.
Why does my Apple Pencil work fine in Word but act glitchy in OneNote?
Different applications use different rendering engines for digital ink. OneNote's specific integration with iPadOS pressure sensitivity can sometimes experience software glitches, whereas Word handles Apple Pencil inputs differently, which is why the thickness issue might not appear there.
Could my Apple Pencil tip cause handwriting to become thick randomly?
Yes, a loose, damaged, or worn-out Apple Pencil tip can occasionally send erratic pressure signals to the iPad's digitizer. Try carefully tightening or replacing the tip to see if it stabilizes the stroke thickness in your notes.
