Reaction Time Test
Measure your reaction speed in milliseconds. Five attempts, one personal best.
Free 5-click reaction time test. Get your average in milliseconds and your best result instantly.
A fast click is only the start. Five attempts tell the fuller story.
What does your reaction time score mean?Speed is relative. Context matters.
This is a visual click test, not a medical measurement. Your screen, browser, input device, sleep and focus all affect the number. Use the table as a playful reference, then compare your own rounds over time.
| Time | Rating | Percentile | Usually this fast |
|---|---|---|---|
| ≤ 150 ms | Excellent | Top 5% | Highly trained players |
| 151–170 ms | Very good | Top 15% | Competitive gamers |
| 171–190 ms | Good | Top 30% | Above-average adults |
| 191–220 ms | Above average | Top 50% | Most healthy adults |
| 221–260 ms | Average | Top 60% | A typical response |
| 261–320 ms | Below average | Top 75% | Tired or distracted days |
| 321–400 ms | Slow | Top 90% | Time for a reset |
| 401–500 ms | Very slow | Top 95% | Try a mouse and a break |
| > 500 ms | Training needed | Bottom 5% | Keep practicing |
What does reaction time measure?
Reaction time is the delay between noticing a signal and starting a response. In this test, the signal is the green screen and the response is a click or tap. A single online result includes more than your reflexes: display refresh, browser timing and input hardware have a say too.
For a more useful baseline, do a full five-attempt round with the same device. Look at the average, not just the luckiest click. If you want a deeper age-by-age comparison, see our average reaction time guide.
Reaction time FAQ
What is a good reaction time?
A visual reaction time around 200–250 ms is typical for many adults. Under 190 ms is generally fast, but your device setup matters.
Why do I get 300 ms or more when I wait for green?
That can be normal in a browser click test. The number includes the display refresh, browser drawing and input device as well as your response. Do not predict the signal: compare full rounds on the same device instead.
How is reaction time measured?
We measure the time from the green signal appearing to your click or tap. The timer uses your browser's high-resolution clock.
Does this work on mobile?
Yes. Tap the large test area. A phone's display and touch hardware may produce different results from a desktop mouse.
What is the reaction time world record?
Records depend on the stimulus, equipment and anticipation rules. Browser click tests are useful for repeated personal practice, not for laboratory or world-record comparisons.
Can I improve my reaction time?
Consistent practice, good sleep and fewer distractions can help. Judge progress across several rounds rather than one exceptional score.
Does monitor refresh rate affect the result?
Yes. Refresh rate, input latency and browser scheduling can each add a small delay, so compare scores on the same setup.
How does this compare to Human Benchmark?
Both use a simple visual cue, but R Test is a privacy-first Human Benchmark alternative: no account, no cloud upload, and your results stay in your browser. It focuses on a five-attempt round, local history and a shareable result card.
Can I save or export results?
Recent scores are saved only in this browser. Export a CSV from the history panel whenever you want a copy.
