A simple, accurate reflex test used by gamers, athletes and drivers.
What is the Reaction Time Test?
Measure how quickly you react to something you see. Click to start, wait for the box to turn from red to green, then click as fast as possible. Your reaction time is shown in milliseconds with your average and best over several tries.
The average human visual reaction time is around 250 ms; trained gamers and athletes are often below 200 ms.
How to use the Reaction Time Test
- Click the blue box to start.
- Wait while it is red – clicking early does not count.
- Click the moment it turns green. Repeat 5 times for a good average.
How to improve reaction time
- Get enough sleep – tiredness slows reactions a lot.
- Practise games and sports that need quick responses.
- Use a wired mouse and a high refresh-rate screen.
- Stay hydrated and avoid distractions.
