Reaction Time Test for Gamers

A normal reaction test puts the target right under your cursor. You never move the mouse, so no movement is in your score.

Games do not work like that. The target appears somewhere you are not pointing, and the clock keeps running while your hand travels.

This test keeps the travel in. So your score here cannot be compared with the simple reaction time test, and it is not meant to be. Subtract one from the other and you get your movement time. That is the part your sensitivity, mouse pad and grip actually change.

The further a target is and the smaller it is, the longer you take to hit it. Paul Fitts put numbers on that in 1954, and seventy years of trying has not broken the rule. It holds on mice, trackpads and touchscreens alike.

One detail is worth knowing. Distance and size do not punish you evenly. Doubling the distance costs less time than halving the target does.

In practice, a small target costs you real milliseconds, and a target at the edge of the canvas costs more than one near the middle. That is why the size setting exists, and why your score only compares against runs at the same size. It is also why grinding tiny targets is a worse use of your time than practising the distance you actually miss at.

Your browser learns where the mouse is on a schedule set by your operating system and your screen refresh rate. Your mouse's own polling rate barely gets a look in. On a 60 Hz screen a 1000 Hz mouse will not beat a 125 Hz mouse by anything measurable here. In a game running at 240 frames per second you would feel the difference.

This test also ignores tracking, switching between targets, recoil control, crosshair placement and reading the game. Those explain far more of who wins than raw flick speed does.

Treat the number as one honest lap time on one narrow skill. If you want pure aiming with no waiting, the aim trainer drops the delay and times thirty targets back to back.

Use the sensitivity you actually play at. Do not lower it to farm a better score. Low sensitivity costs you travel time and high sensitivity costs you accuracy. The setting that gives your best median here is usually close to the one you should be playing on.

Do not move the cursor back to the middle between targets. The delay is random so that pre-aiming does not pay. Recentring turns the test into a fixed-distance drill that flatters you.

For where these numbers sit across the population, see average reaction time by age. Remember its curve comes from tests with no movement in them. What counts as a good reaction time explains why your equipment shifts these figures more than your talent does.
