Controller Deadzone Test
Let go of the sticks, then circle them around the edge, and get the lowest deadzone that still hides your drift.

How It Works
A deadzone is the area around a stick’s center that a game ignores, so a stick resting slightly off center does not move your character. Too small and the character creeps on its own; too large and small, precise movements are lost.
The test first records both sticks for 3 seconds with your hands off, to find where each one rests and how much it jitters. Then you move each stick slowly out from the center and around the edge 2 times, which traces how far it reaches in 8 directions.
Deadzones can stack up in three places: the controller’s firmware, the driver or browser, and the game. If a stick reads exactly 0.000 at rest and jumps past a small value as soon as it moves, the controller is filtering it before any game sees it.
The slider tries any deadzone on your own movement. A radial deadzone ignores a circle around the center. An axial deadzone ignores each axis on its own, a cross shape, which is why slow diagonal movement can snap to straight lines in some games. Gray trail points are ignored; amber ones lose one axis.
Interpreting Your Result
The recommended deadzone is where your stick rests plus its jitter, with 0.02 to spare: the lowest setting that stops drift. Enter it as the game’s inner deadzone, or left and right stick deadzone. Games show it as a number from 0 to 1 or as a percentage: 0.06 is 6%.
Going higher than you need costs fine aim. Every small movement inside the deadzone is thrown away, so aiming feels sticky and then jumps.
Every direction should reach 0.95 or more. A direction that falls short, a flat spot, usually means a worn or cracked gate ring around the stick: a cheap part that can be replaced.
If a stick reaches less than 1.00 somewhere, lower the game’s outer deadzone to the value shown, so the stick still reaches full speed in every direction.
Squared corners are normal. Each axis stops at ±1, so pushing diagonally can read past 1.00.
A stick resting inside the controller’s built-in deadzone has drift no game will ever see. The flip side is that drift that small cannot be measured here either.
Want a clear yes or no on drift? The stick drift test grades each stick at rest, and the gamepad tester checks every button.
Frequently Asked Questions
What deadzone value should I use?
The lowest one that stops your character or camera moving on its own. This test measures that for each stick: where it rests, plus its jitter, plus a small margin. For most healthy controllers it is between 0.03 and 0.10, or 3% to 10%.
Should I set my deadzone to 0?
Only if this test recommends 0, which happens when the controller already filters its own sticks. Otherwise a deadzone of 0 lets the smallest resting offset move your character or camera. Use the recommended value instead: it is as low as it can go without drift showing.
What is the difference between radial and axial deadzone?
A radial deadzone ignores a circle around the center, so movement in every direction starts at the same point and diagonals stay smooth. An axial deadzone ignores each axis separately, a cross shape, so a slow diagonal loses one axis first and snaps to a straight line. Radial is better for aiming.
What is the difference between inner and outer deadzone?
The inner deadzone is ignored movement around the center, which hides drift. The outer deadzone is the point near the edge where the game treats the stick as fully pushed. Lowering it helps a worn stick that no longer reaches 1.00 still reach full speed.
Why does my stick not reach the edge?
Usually a worn gate ring, the plastic collar the stick rubs against, or a worn sensor. If one direction falls short, it is the gate; if every direction does, it is more likely the sensor. Lowering the outer deadzone in your game works around both.
Why does the range look square?
Each axis of a stick is reported from −1 to 1, and many controllers let the diagonal reach both limits at once. Pushed diagonally, the stick then reads past 1.00 from center, so the outline has squared corners. That is normal, not a fault.
Does a higher deadzone fix stick drift?
It hides it. A deadzone just larger than the drift stops it moving your character, at the cost of some fine aim. If the drift keeps growing, the stick needs cleaning or replacing, and a higher deadzone will only hide it for a while.
