Test your reaction time in milliseconds
Click the panel below to start. When it turns green, click as fast as you can. We'll run five rounds, drop your fastest and slowest for fairness, and tell you what percentile you sit in.
Other tests you can run
Six variations on the reaction time test. Each measures a slightly different aspect of how your brain translates signals into action.
Reaction Test
A simpler single-round version. One click, one number — the fastest possible way to check your reflexes.
Reaction Speed Test
Speed-focused variant that emphasises your fastest click across multiple rounds rather than your average.
Audio Reaction Test
React to a beep instead of a visual cue. Auditory RT is usually 20–40 ms faster than visual RT.
Aim Trainer
Tap 30 targets as fast as you can. Measures target acquisition time — closer to FPS gaming than simple RT.
Sequence Reaction Test
Four pads, one lights up. Tests choice reaction time — your brain has to decide which pad to tap.
Number Memory Test
Memorise progressively longer numbers. Tests working memory, which correlates with reaction time.
Where do you sit? Average reaction time, explained
The numbers below come from a mix of published research and aggregated web-test data. Use them as a rough reference, not a verdict on your nervous system.
| Percentile | Reaction time | Notes |
|---|---|---|
| Top 1% (elite) | 175 ms | Competitive esports territory. |
| Top 5% | 195 ms | Competitive esports territory. |
| Top 10% | 210 ms | Faster than most adults. |
| Top 25% (above average) | 230 ms | Faster than most adults. |
| Median (50%) | 250 ms | The reference adult median. |
| Bottom 25% (below average) | 280 ms | Slower than average but normal. |
| Bottom 10% | 320 ms | Slow — usually fatigue or input lag. |
| Bottom 5% | 360 ms | Slow — usually fatigue or input lag. |
The "250 ms average" you see quoted everywhere is the median for adults aged 20–29 on a simple visual RT task. Teenagers are about 15 ms faster; people over 60 are about 60 ms slower. There is no single "human average."
Single attempts are noisy. Your fastest might be a lucky guess (you started moving before green), and your slowest might be a distraction. Trimming both gives a more honest average.
Reaction time by age
Reaction time peaks in your late teens and slowly declines. The drop isn't dramatic — most adults in their 40s are within 25 ms of their teenage peak.
| Age range | Average | Fast (top 5%) |
|---|---|---|
| Ages 6–9 | 290 ms | 240 ms |
| Ages 10–13 | 260 ms | 215 ms |
| Ages 14–19 | 235 ms | 195 ms |
| Ages 20–29 | 245 ms | 200 ms |
| Ages 30–39 | 255 ms | 210 ms |
| Ages 40–49 | 270 ms | 225 ms |
| Ages 50–59 | 290 ms | 245 ms |
| Ages 60–69 | 315 ms | 265 ms |
| Ages 70+ | 355 ms | 300 ms |
