Click Start, wait for the box to turn green, then click as fast as you can. You get 5 tries, and your average in milliseconds is your reaction time.
⚠️ Results depend on your monitor, mouse/trackpad and browser. For comparable numbers, use the same device and browser.
Every figure below comes from the reaction time test on this page — the real results visitors have chosen to add, not a textbook average. The rating scale beside the test uses these same results; this table shows exactly how you compare with everyone else who has taken it. Based on more than 9,000 results, updated October 2026.
| Your average | Ranked against results from this test |
|---|---|
| Under 200 ms | Faster than about 96% |
| 200–250 ms | Faster than 72–96% |
| 250–300 ms | Faster than 47–72% |
| 300–350 ms | Faster than 29–47% |
| 350–450 ms | Faster than 8–29% |
| Over 450 ms | Slower than about 92% |
Half of everyone who has taken the reaction time test on this page averages faster than 294 ms, and three in four are faster than 362 ms. Getting under 250 ms puts you ahead of about 72% of results, and under 200 ms puts you in the fastest 4%. Scores from this test run slower than the figures you'll see quoted from laboratory studies, because those use dedicated hardware — testing your reflexes through a browser adds time from your screen, your mouse or trackpad, and the page itself. That's also why it's worth comparing yourself on the same device each time rather than against someone else's setup.

Taking the test a hundred more times won't change much. Sleep, focus and your setup move the number most. These guides cover what actually helps.
