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.
The median is about 273ms. That's the figure observed across large online reaction-time datasets, and 250–300ms is the typical average range.
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 |
To a degree. Reaction time is largely innate, but repeating the same task usually makes you a little faster as you get used to it. That said, this is mostly familiarity with this test rather than a broad gain in reflexes.
Lack of sleep, fatigue, and too much caffeine all slow reactions, so looking after your condition is the most reliable lever. Reaction time also tends to slow with age, so the same person will see different results over time.
