Reaction Time Test

What is this test?

The reaction time test measures, in milliseconds (ms), how long it takes your body to actually react after perceiving a visual cue. It's commonly used as a measure of a gamer's reflexes — the average human reaction time is roughly 200–250ms.

How to take the test

Click the screen to enter the waiting state, then click as fast as you can the instant it turns from red to green. Clicking too early counts as a false start. This is repeated 5 times, and your average is calculated.

What does the score mean?

A lower score (fewer ms) means a faster reaction time. Save your result to see how you rank against every other user on the leaderboard. View Reaction Time Rankings →

Known Records

The average adult reaction time is generally cited as 200–250ms. Elite esports players average around 150–225ms — noticeably faster than untrained players. The physiological floor for a human visual reaction is roughly 100ms, so times faster than that aren't realistically possible.

What Affects Measurement Accuracy

Display refresh rate, input device latency, and browser rendering speed can all affect your measured time. High-refresh monitors (144Hz+) tend to measure more accurately than 60Hz ones, and wired mice typically have less latency than wireless ones.

Typical Result Range

Untrained adults typically score 250-350ms, regular practicers around 200ms, and pro-level players 150-180ms. Anything under 100ms is likely a measurement glitch rather than a real result, since it falls below human physiological limits.

How to Improve Your Score

Keep your eyes and hand pre-positioned near where the screen will turn green rather than scanning the whole screen — this cuts down on reaction lag. Repeating the test to lower your average also genuinely trains reflexes, and getting enough sleep affects reaction speed too.
