How much stick drift is normal?
No drift (under 2%): nothing to fix. Minor drift (2 to 8%): set the recommended deadzone in the game or Steam; the stick will keep working for a long time. Stick drift detected (above 8%): a deadzone will mask it for now, but the potentiometer is worn and the value will grow. Plan a warranty claim or a stick module replacement.
The average deviation tells you whether the drift is constant (max and average almost equal) or intermittent (average much lower than max). Intermittent drift often comes from debris or a damaged stick cap and can sometimes be cleaned.
From drift test to calibration
Take the recommended deadzone to the calibration tool to see the corrected output, then apply it in the place that matters for you: the game's settings, Steam Input, the Switch system calibration, the Windows joystick tool or, for DualShock 4 and DualSense, the USB recalibration on this site's calibration page. Each platform guide on this site explains the exact menu path.
Frequently asked questions
Should I test drift with the controller on a table or in my hands?
On a table. Holding the controller adds tiny movements that look like drift. Put it down, take your hands away and press Start with a mouse or keyboard.
Why does the drift result change between tests?
Potentiometer wear is not uniform, and temperature affects the resting value. Run the test three times and use the highest result when choosing a deadzone.
