Click the instant the screen color changes
A reaction time test measures, in milliseconds (ms), how quickly you click after visually noticing a color change on screen. The lower the number, the faster your reaction speed. It's a common indicator of split-second responsiveness used in gaming and sports.
Visual reaction time typically falls in the 250–300ms range for most people. Low 200s is faster than average, and 150–200ms is a well-trained level. Results can shift by 10–50ms depending on your device, monitor refresh rate, and touchscreen latency.
| Average time | Interpretation |
|---|---|
| 150ms or less | Very fast (world record is around 120ms) |
| 150–220ms | Fast — good reflexes for gaming/sports |
| 220–300ms | Typical average range |
| 300ms+ | May reflect fatigue, low focus, or device lag |
A single try is less reliable than an average of 5+ tries. Cold hands, drowsiness, wireless mice, or mobile touch input can all add extra delay — repeat under the same device/environment to compare fairly. Clicking before the color actually changes won't give you a true reaction time reading.
