Reaction time test

Test your reaction time with a visual click test. Track multiple attempts and compare sessions under the same conditions.

  • Free
  • No account needed
  • Works in your browser

Keep the comparison fair

  • Use the same browser, display, mouse, and polling settings.
  • Take several attempts instead of chasing one best click.
  • Test at similar times when comparing days.

What this test measures

Visual reaction time in milliseconds.

Adults average about 231 ms on a computer click test, according to a study of 1,469 people (Woods et al., 2015). Click as fast as you can when the screen turns green. The test records the time between the color change and your click in milliseconds. Run 5 or more attempts and compare the average.

Inputs: Your clicks in response to a random color change.

Output: Reaction time in ms, attempt history, and session average.

Limitations: Measures visual click response only. Results are affected by display latency, input device, and browser timing. Does not predict in-game performance, which involves anticipation, visual search, and decision-making.

Reaction time in competitive gaming

What the numbers actually mean and why context matters more than raw speed.

A reaction time test measures the delay between seeing a stimulus and clicking. In gaming, this translates to how quickly you can respond to an unexpected event: an enemy peeking, a flash appearing, or a sound cue.

But raw reaction time is only part of the picture. In competitive FPS, most engagements are won by the player who predicted the encounter, not the one who reacted fastest. Crosshair placement, positioning, and pre-aiming reduce the need for raw reaction speed.

Factors that affect your score

Hardware, biology, and environment all play a role.

Display timing: A refresh interval is about 16.7ms at 60Hz, 6.9ms at 144Hz, and 4.2ms at 240Hz. That describes when a frame may be presented, not your complete end-to-end latency or biological reaction time.

Input device: Wired, Bluetooth, and 2.4GHz mice can have different timing characteristics. Polling intervals are approximately 8ms at 125Hz, 1ms at 1000Hz, and 0.25ms at 4000Hz, but those figures do not describe total device or system latency.

Context: Sleep, stress, distractions, time of day, and familiarity with the test can shift a session. Keep those conditions reasonably consistent when comparing results.

Practice: Repeated testing can improve consistency and task familiarity. For gameplay, drills that combine a response with aiming, target selection, and prediction are more useful than chasing a browser score.

Average reaction time by age

Average simple reaction time on a computer click test, from a study of 1,469 adults. The average rises about half a millisecond per year of age.

AgeAverage reaction time
18-24218 ms
25-31221 ms
32-38225 ms
39-45228 ms
46-51234 ms
52-58236 ms
59-65239 ms
All ages (18-65)231 ms

These times include about 18 ms of monitor and mouse delay; without it the overall average was 213 ms. A browser test on a 60Hz screen can add more, so compare your own average across sessions on the same setup.

Reaction time FAQ

What's fast, what matters, and how to improve.

Anything under about 230 ms beats the adult average. In a study of 1,469 adults, the average on a computer click test was 231 ms, and 18 to 24 year olds averaged 218 ms (Woods et al., 2015). Judge yourself by the average of 5 or more attempts, not your single best click.
Yes, if it holds across several attempts. 150 ms is about 80 ms faster than the 231 ms adult average in Woods et al. (2015). Single results this fast are often anticipation, clicking because you expect the change, so check your session average.
Yes. 170 ms is about 60 ms faster than the 231 ms adult average and 48 ms faster than the 218 ms average for 18 to 24 year olds in Woods et al. (2015).
Yes. 180 ms is about 50 ms faster than the 231 ms adult average measured on computers in Woods et al. (2015).
Yes. 190 ms is about 40 ms faster than the 231 ms adult average and faster than the 218 ms average for 18 to 24 year olds in Woods et al. (2015).
Yes. 200 ms is faster than the 231 ms adult average and the 218 ms average for 18 to 24 year olds in a study of 1,469 adults (Woods et al., 2015).
Yes, it's normal to slightly fast. 220 ms is about 10 ms faster than the 231 ms adult average and close to the 218 ms average for 18 to 24 year olds (Woods et al., 2015).
It's about average. Adults averaged 231 ms in Woods et al. (2015), and a 60Hz screen alone can add up to 17 ms before the color change even appears. On a 144Hz or faster setup, the same reflexes usually read a little lower.
It's slightly slower than the 231 ms adult average, by about as much as hardware can add. A 60Hz display, a Bluetooth mouse or a TV outside game mode each add delay, so test on the setup you actually play on before reading much into it.
It's slower than average, by about 70 ms. Retest first: tiredness, distractions, a TV picture mode or a wireless mouse can all add delay. If it stays near 300 ms across sessions on a fast setup, treat it as your baseline to improve from.
No large public dataset measures pro players on one standard test, so treat any single pro average with caution. Studies that compare esports players with other groups use small samples and different tasks, which is why their numbers disagree.
No large study measures gamers separately on a standard test. Adults in general averaged 231 ms on a computer click test in Woods et al. (2015), with 1,469 people aged 18 to 65, and the average rose about 0.55 ms per year of age.
It can affect when a visual change is presented. One refresh interval is about 16.7ms at 60Hz, 6.9ms at 144Hz, and 4.2ms at 240Hz. That is display timing, not a guaranteed change in your biological reaction speed.
Both inherited traits and practice can matter, but the size of any improvement depends on the task and the person. Practice can also make you more familiar with a test. In games, anticipation and decision-making often matter more than a raw click score.
Sleep, stress, distractions, time of day, and familiarity with the test can all affect a session. Compare your own results under similar conditions before reading meaning into a change of a few milliseconds.
Input timing can affect the measured result, especially when comparing very different devices. Bluetooth, wired, and 2.4GHz implementations vary, so use the same mouse and polling settings when tracking yourself. There is no universal minimum required for this test.
You can often improve consistency and familiarity with a task through practice, but the amount varies. Game-specific drills that include visual decisions and prediction are usually more relevant than clicking the same browser test repeatedly.
