Reaction time test

Click the pad to begin. Wait for it to turn green, then click as fast as you can. Clicking too early resets the attempt.

This tests the time between a visual signal and your physical response to it — the same basic mechanic used to measure reaction speed in gaming benchmarks and, in a real-world form, sprint starting blocks. Click the pad to arm it, wait through a random delay, and the instant it turns green, click again. The gap between the color change and your click is your reaction time in milliseconds.

The delay before green is randomized on purpose so you can't anticipate it by rhythm — clicking before the color changes just resets the attempt rather than giving you a fake fast time. Run it a few times; the "average (last 5)" figure is a more honest measure of your reflexes than any single lucky result.

What's a good reaction time?

The average human reaction time to a visual cue is around 250 milliseconds. Trained gamers and esports competitors often land in the 150–200ms range. Anything under 150ms is exceptional and can sometimes reflect a lucky early guess rather than pure reflex, which is why testing multiple attempts and looking at your average matters more than a single fast result.

Why did it say "too soon"?

If you click before the pad turns green, the attempt doesn't count as a real reaction, since you reacted to nothing. The test resets so you can try again with a fresh random delay.

Why is the delay random each time?

A random wait time prevents you from timing your click based on rhythm or memory, which keeps the test measuring actual reaction speed rather than pattern guessing.

Does this work on mobile?

Yes, you can tap the pad the same way you'd click it on desktop.

What's a good reaction time for gamers?

Competitive players in fast-paced shooters typically aim for under 200ms, with top esports competitors often landing between 150 and 180ms. Casual players usually fall in the 220-300ms range, which is close to the general population average.

Does reaction time change with age?

Yes. Reaction speed tends to peak in the mid-20s and gradually slows afterward, though regular practice and good sleep can help offset some of that decline.

Is visual reaction time the same as auditory reaction time?

No, most people react slightly faster to sounds than to visual changes. This test measures visual reaction time specifically, since that's what matters most in situations like gaming and driving.
