Reaction Time Test

When red turns green, click as fast as you can. Five rounds, averaged. The median is about 275 ms - where do you land?

How the reaction time test works

The box turns red while you wait, then green after a random delay of 1.5 to 4.5 seconds. The moment it flips, click (or press space). We time the gap between the color change and your input, repeat it five times, and average the rounds. Clicking early counts as a false start and restarts the round, so you cannot cheat by spamming.

What counts as fast?

Around 275 ms is the human median for visual stimuli. Regular gamers usually sit between 180 and 230 ms. Elite esports players and F1 drivers reach into the 140-170 ms range. Your score includes your hardware's latency - a high refresh rate monitor and a wired mouse can legitimately buy you 10-30 ms.

What is a good reaction time?

The median is around 250-280 ms. Under 200 ms is excellent, and competitive gamers often average 150-190 ms. Under 100 ms is usually anticipation, not reaction.

Can I improve my reaction time?

Yes, to a point. Sleep, hydration, caffeine timing and daily practice all help. Most people can shave 20-40 ms off their average with consistent practice, though genetics set the floor.

Why is my reaction time different on my phone?

Touchscreens add input latency and refresh rates differ. For your fastest scores use a desktop with a high refresh monitor and a mouse - and always compare scores from the same device.
