Controller stick drift test
Leave a controller's sticks alone to read how far off centre they rest, and circle them to check their range. Free, with no account or uploads.
Read your sticks' drift
Press a button to connect, leave both sticks alone and press Read drift. Drift the controller's own deadzone hides cannot be seen.
Connect a controller and press any button on it.
Browsers show a controller to a page only after one of its buttons is pressed, so that a page cannot learn what is plugged in.
Everything happens in your browser. Nothing you press is sent anywhere or kept.
A little help along the way
Follow these steps. Every option is explained underneath. Everything happens in your browser; nothing you press is sent anywhere.
- Choose your keyboardThe shape (ANSI, ISO, JIS, ABNT2, Korean or Mac) is guessed from your system; change it if it is wrong, and choose the size: full, tenkeyless, 75%, 65%, 60% or the number pad.
- Click the board and press your keysEach key lights while held and keeps a tick once it has worked. The site's own shortcuts step aside while you test. Press Escape twice to leave.
- Hold several at onceTo test ghosting and rollover, hold many keys together; the result keeps the most held at once.
- Read the resultIt says how many keys have worked, which are still to press, the most held at once, and any key that bounced.
Questions people ask
- How do I test for stick drift?
- Connect the controller, press a button, leave both sticks alone and press Read drift. It reads them for three seconds and says how far off centre they rested.
- How much drift is too much?
- Under about 10% of the way to the edge is hidden by most games' deadzones. More than that can move a game without you touching the stick.
- Can a page see all drift?
- No. A controller's own deadzone can hide small drift before any page is told, so a stick that reads clean here may still drift a little.
This page is the Keyboard tester, opened for this one job; every other tool it has is one press away. Each of its settings is explained on the Keyboard tester's own page.
