Fix PowerPoint Apple Pencil First Stroke Thickness Issue on iPad
Question details
The user experiences an issue where the first stroke made with an Apple Pencil in PowerPoint for iPad applies an incorrect pen width.
- Product
- Microsoft PowerPoint for iPad
- Device & OS
- iPadOS
- Scenario
- Drawing, handwriting, or annotating on slides using an Apple Pencil within the PowerPoint app.
- Observed behavior
- The first stroke drawn with the Apple Pencil does not match the selected pen thickness, although subsequent strokes may appear normal.
Ensure your Apple Pencil is fully charged and securely paired with your iPad via Bluetooth, and test the stylus in another app (like Apple Notes) to rule out hardware defects.
Update PowerPoint and iPadOS to the Latest Version
Software bugs affecting Apple Pencil rendering and pressure sensitivity are frequently patched in new system and application updates.
Compatibility issues between the iPadOS touch input framework and third-party apps can sometimes cause the initial touch event to miscalculate pen thickness. Updating ensures you have the latest bug fixes from Microsoft and Apple.
Open the App Store on your iPad, tap your profile picture at the top right, scroll down to check for pending updates, and tap 'Update' next to Microsoft PowerPoint if available.
Navigate to your iPad Settings, tap 'General', and select 'Software Update'. If an update is available, download and install it.
Restart your iPad, open PowerPoint, select the pen tool from the Draw tab, and test the first stroke on a slide.
Isolate the Issue and Report to Microsoft
Determine if the bug is isolated to the first slide or occurs globally, and send diagnostic feedback to Microsoft for a permanent fix.

Frequently Asked Questions
Why does the Apple Pencil glitch on the first stroke in PowerPoint?
This is typically caused by app-specific rendering delays where PowerPoint temporarily fails to register the Apple Pencil's pressure or selected thickness settings on the initial point of contact.
Can I change the default pen thickness in PowerPoint for iPad?
Yes, you can tap the pen tool twice in the Draw tab to access a drop-down menu containing thickness and color settings. However, rendering bugs may still override this setting on the very first stroke.
Does this thickness issue happen with other styluses?
While it can happen with third-party styluses, it is predominantly reported with the Apple Pencil on iPadOS due to the specific way the Microsoft app processes Apple's proprietary pressure and tilt data.
Is there a temporary workaround for the incorrect first stroke?
As a quick workaround, you can make a small dot or scribble off to the edge of the slide to 'prime' the pen, then immediately draw your intended stroke with the correct thickness.
