Palm rejection for drawing: what to check

Your hand rests on the tablet while you draw, then an unwanted mark appears, the canvas moves, or a button gets tapped. That can happen when the device or drawing app treats your palm as finger input instead of ignoring it.

Start by checking the touchscreen, then test the stylus and drawing app separately. The Touch Screen Test can show whether the screen registers contact points or has dead zones, but it cannot certify palm rejection or measure stylus pressure.

Test palm rejection during a drawing session

1. Open the Touch Screen Test on the device you draw on. Touch the screen with one finger, then add a second finger and check whether the test responds to both.
2. Rest your drawing hand on the screen as you normally would. Watch for extra contact points or unexpected movement. A browser may not identify a contact specifically as a palm, so treat this as a check for unwanted touch input, not a definitive palm rejection test.
3. Open your usual drawing app and make a few slow strokes with the stylus while resting your palm naturally. Repeat with your hand lifted, then compare whether marks, canvas movement, or accidental taps occur.
4. If possible, test another drawing app or another supported stylus on the same device. Change one thing at a time so you can tell whether the issue follows the screen, stylus, or app.

Use a blank canvas or a copy of your work. Avoid testing over important artwork, since accidental touches can still create edits in an app even if you undo them afterward.

What the result means

The browser test shows unwanted contacts when your hand rests

The device is sending touch input from the resting hand to the browser. This does not prove the drawing app will behave the same way, because an app may filter contacts differently. Check the app's palm rejection settings and repeat the test with the stylus active.

The browser test responds to fingers, but drawing is clean

The touchscreen is registering ordinary touches, while the drawing setup is filtering your palm successfully. That is normal. Palm rejection usually depends on the stylus, operating system, and app working together, rather than on the screen ignoring every touch.

Accidental marks happen only in one drawing app

The app may have palm rejection turned off, may not support your stylus, or may interpret the stylus input incorrectly. Check that app's input settings and confirm the stylus is selected as the drawing tool.

The issue happens in several apps, or the stylus is not detected

Check stylus compatibility, pairing, charge, and system settings. If the screen also misses finger touches or shows a dead area in the Touch Screen Test, the problem may involve the touchscreen rather than palm rejection alone.

How to fix unwanted palm touches

1. Check how you hold the stylus. Keep the tip in contact with the screen before resting your hand, if your device or app uses stylus-first palm filtering. Some systems ignore touch only while a compatible pen is active.
2. Turn on palm rejection in the drawing app. Look in the app's stylus, touch, or input settings for palm rejection, touch rejection, or a setting that allows drawing only with the pen. The exact name and location vary by app.
3. Confirm the stylus is supported and connected. A basic capacitive stylus behaves like a finger and may not provide the signals needed for palm rejection. Use a pen that is compatible with your tablet, and check its battery or pairing if it is an active stylus.
4. Check the device's pen settings. On Windows 11, open Settings › Bluetooth & devices › Pen & Windows Ink and review any pen and touch options available on your device. On an iPad, open Settings › Apple Pencil and check the available Pencil options, including Only Draw with Apple Pencil if your model and software show it. Android options vary by manufacturer; check the drawing app and the device's stylus settings.
5. Update and restart the app and device. Install available updates for the drawing app and operating system, then restart the tablet. A temporary input or pairing issue can clear after a restart.
6. Check the tablet or pen manufacturer's driver utility. On a Windows computer or Mac using an external drawing tablet, open the tablet's own settings app and review pen and touch options. macOS does not have a general built-in touchscreen palm rejection setting, so an external tablet's driver and the drawing app control the available behavior.
7. Test without accessories that affect contact. Remove a thick or damaged screen protector and clean the screen with a suitable soft cloth. If the issue changes, the protector or surface may be interfering with touch input.

When it may be a hardware problem

If finger touches appear in the wrong places, a section of the screen misses taps, or unwanted contacts continue across several apps with a compatible stylus, test the screen again without a case or screen protector. A persistent dead zone or erratic touch response points to a touchscreen problem, not just poor palm rejection. Contact the device or tablet maker while it is under warranty, or ask a repair shop to inspect the display and digitizer.

Why the touchscreen test has limits

The Touch Screen Test checks touch points and dead zones through the browser. It does not know whether a contact came from a palm, finger, or stylus, and it cannot change how the operating system filters input. Some browsers and devices also report touch information differently.

A useful drawing check therefore has two parts: use the browser test to look for basic screen response problems, then test palm rejection in the drawing app with your actual stylus and normal hand position. A clean result in one app does not guarantee the same behavior in every app.
