Just want a quick check? Use the gamepad tester or the stick drift test.
- A resting value up to 0.02 is normal. Your suggested deadzone is that value plus a small margin.
- A healthy stick reaches 0.98 to 1.00 at the edge in every direction.
- Circularity error under 10% is very round; 10–20% is fine; over 20% is noticeably uneven.
- Use the smallest deadzone that still stops drift.
What is a deadzone?
A deadzone is a small area around the stick's center that a game ignores. If the stick sits slightly off-center, or wobbles a little, the game doesn't move your character.
There are two kinds:
- Inner deadzone: the zone in the middle that's ignored. It hides drift and wobble.
- Outer deadzone: the zone near the edge where the game already counts the stick as fully pushed. It makes sure you can reach full speed even if your stick falls a bit short.
Too small an inner deadzone lets drift through. Too big a deadzone makes small aiming movements feel dead. The goal is the smallest deadzone that still stops drift.
How to run the test
- Connect your controller and press any button.
- Rest test: let go of both sticks for 5 seconds. The tool records the largest resting value.
- Circle test: roll each stick slowly around the very edge, 3 full turns each way. Keep pressing outward the whole time.
- Read your results for each stick.
How to read your results
Rest value (your inner deadzone)
This is how far from 0.00 the stick sits when you let go. Up to 0.02 is normal. Higher values mean drift. Your suggested inner deadzone is your rest value plus a small safety margin.
Outer range
This is how far the stick reaches at the edge, from 0.00 to 1.00, in its weakest direction. A healthy stick reaches 0.98 to 1.00 in every direction. If one direction stops at 0.90, you won't get full speed that way in some games, unless you set an outer deadzone.
Circularity error
When you roll the stick around the edge, a perfect stick would trace a perfect circle. Circularity error shows how far your stick's path is from that circle, on average, as a percentage. The pink outline on each map is your stick's real path.
| Circularity error | What it means |
|---|---|
| Under 10% | Very round. Smooth, even movement in every direction. |
| 10% – 20% | Fine for most players. Diagonals may feel slightly different. |
| Over 20% | Noticeably uneven. Some directions are faster or slower than others. |
These ranges are a rule of thumb. Some controllers are built to reach past the circle on the diagonals, which raises the error without any fault. Compare both sticks on the same controller. A big difference between them says more than the number alone.
How to set your deadzone in games
- Run the rest test and note your suggested deadzone.
- Open your game's controller settings. Look for "deadzone", "inner deadzone" or "stick sensitivity".
- Set the inner deadzone to the suggested value, or the nearest option.
- Play for a few minutes. If drift is gone and aim feels responsive, you're done.
Games show deadzones in different ways. Some use 0 to 1, some use percent (0.08 = 8%), and some use a 1–10 scale. Convert as needed.
If your game has no deadzone setting, Steam's controller settings can add one for games launched through Steam.
Why do deadzones matter for competitive players?
In shooters, a smaller deadzone means your aim reacts to tiny thumb movements. Many players turn the deadzone down as low as they can without drift. This test tells you exactly how low you can go. As your stick wears, retest every few months, because the safe value goes up over time.
Deadzone and circularity test FAQ
What deadzone should I use?
Use your rest value plus a small margin. For a healthy stick that's often around 0.03–0.05. For a drifting stick it will be higher.
Is a 0% deadzone good?
Only if your stick has no drift at all. Most sticks have a little noise, so 0% often causes slight movement when you aren't touching it.
What does "average error" mean on a gamepad tester?
It's the circularity error: how far, on average, the stick's path at the edge is from a perfect circle.
Can I fix a high circularity error?
Sometimes. Recalibrating can help if the stick doesn't reach full range. If it's caused by wear or the shape of the stick's housing, a new stick is the only full fix. See controller calibration.
Why are my two sticks different?
Each stick wears on its own. The left stick is used more in most games, so it often wears first.
