How the reaction time test works
- Click the box to start. It turns red — wait.
- After a random delay of 1.5 to 4.5 seconds it turns green.
- Click as fast as you can. Your time appears in milliseconds.
- After five tries you get your average and your single best time.
Clicking while the box is still red doesn't count against you; you just redo that try. Because the delay is random, guessing never helps. You can also press the space bar instead of clicking.
What is a good reaction time?
Most people average somewhere between 200 and 300 milliseconds on a visual click test like this. Here is how we rate your average:
- Under 200 ms — Lightning. Exceptionally fast.
- 200 to 250 ms — Fast. Quicker than most people.
- 250 to 300 ms — Typical. Right in the normal range.
- 300 to 350 ms — Relaxed. Try again when you're fully focused.
- Over 350 ms — Sleepy. Maybe a coffee break first?
Your device adds a little delay too: wireless mice, slow screens and busy computers can each add a few milliseconds. Compare scores on the same device.
Frequently asked questions
Can I improve my reaction time?
Sleep, focus and practice all help. Rhythm and timing games that reward clicking at an exact moment, like Circle Clicker, train a closely related skill: anticipating the moment instead of just reacting to it.
Why is my phone slower than my computer?
Touchscreens and mobile browsers usually add more input delay than a wired mouse, so the same person often scores a little slower on a phone.
