01Step 1: Pick a test mode
Choose Visual (click the instant the box turns green) to measure pure reaction time in milliseconds, Audio (click on the beep) to test how fast you respond to sound, or Go/No-Go (click on green, hold on red) to measure impulse...
02Step 2: Run the best-of-5 protocol
Click the box to begin, then wait through the random 2–5 second delay — clicking early shows "Too early" and does not count. The instant the signal fires, click as fast as you can.
03Step 3: Read your reaction time stats
The result card reports your average and median in milliseconds plus a consistency score (±standard deviation) so you can tell raw speed from steadiness.
04Step 4: Improve and retest
To improve your reaction time, do two or three warm-up rounds first, sit close to the screen, and cut input lag with a high-refresh-rate monitor and a low-latency wired mouse.
A reaction time test measures how quickly you respond to a signal, in milliseconds. Pick a mode - Visual (click on green), Audio (click on the beep), or Go/No-Go (click on green, hold on red) - then complete a best-of-5 protocol. The tool reports your last, best, average, median, and consistency (standard deviation), plus a tier verdict, percentile, and by-age comparison.
What is a good reaction time, and what do the ratings mean?
The average human visual reaction time is roughly 200-280 ms, with large samples centering near 273-284 ms. This tool maps your best-of-5 average to five tiers: under 150 ms is Elite (top esports and pro-athlete level), 150-200 ms is Pro Gamer (well above average), 200-250 ms is Average for a healthy rested adult, 250-300 ms is Slow (try warming up), and 300 ms or more usually points to fatigue or distraction.
What is the average reaction time by age?
Reaction speed peaks in the mid-20s at around 200 ms and slows gradually with age - roughly 215 ms in your teens, 215 ms at 30-39, 240 ms in your 40s, 265 ms in your 50s, and about 320 ms past 70. Enter your age on the result screen and the tool compares your measured average to this curve to tell you which age your reflexes match and whether it is good for your age.
How can I improve my reaction time?
Warm up with two or three practice rounds, stay focused, get enough sleep, and test when rested rather than fatigued. Cut input lag with a high-refresh-rate monitor and a low-latency wired mouse, and sit close to the screen. Regular practice and consistency training lower your average over weeks; always retest on the same device so gains reflect your reflexes, not different hardware.
Why are my browser results higher than other reaction tests?
Display latency, mouse or touchscreen click latency, and browser processing add a roughly constant offset to every attempt, so browser results can read 10-20 ms higher than a dedicated peripheral benchmark. The tool uses high-resolution performance.now() timing to minimize jitter, so compare scores taken on the same setup rather than across different devices.
Why are very fast times (under 100 ms) thrown out?
Anything under 100 ms is physiologically impossible as a true reaction - World Athletics treats a sprint start faster than 100 ms as a false start - so it is a guess or an early click. The tool voids those attempts without recording them, which keeps your average and percentile honest. Your history is stored only in your own browser via localStorage and nothing is uploaded.
