Average Reaction Time

Average human reaction time at a glance

Large online datasets put the median simple click score near 270 ms. That figure includes the small delay of ordinary screens and mice. Lab studies with special equipment report faster averages for the same task.

So a normal human reaction time depends on how you measure it. Compare yourself with numbers from the same type of test.

Average reaction time by test type

Each of our tests measures something slightly different, so each has its own normal range.

Average reaction time by age

Reaction speed improves through childhood, peaks in the late teens and twenties, then slows slowly. The change is gradual: a healthy 60-year-old is often only 40 to 60 ms slower than a 25-year-old on a simple task. Choice reactions slow more with age than simple ones.

Staying active, sleeping well and keeping your hands and eyes busy with games or sport all help slow the decline.

Visual, sound and touch averages

Hearing and touch reach the brain faster than vision. In classic lab work, simple sound reactions average around 140 to 160 ms and light reactions around 180 to 200 ms.

Why your device shifts the average

A 60 Hz screen draws a new image every 16.7 ms, so the green signal can appear up to one frame late. Wireless mice, touchscreens and Bluetooth audio add more. Altogether, home devices can add anywhere from 10 to over 100 ms.

This is why gaming setups with fast monitors and wired mice post lower scores. It also means you should judge your progress on one device.

Average reaction time for gamers, drivers and athletes

Gamers who play fast shooters often score 150 to 200 ms on simple online tests. Part of that is practice, and part is gear: fast monitors and wired mice cut the hidden delay.

F1 drivers usually react to the start lights in about 0.2 seconds, but they know the lights are coming and have trained for years. Sprinters work under a rule that treats any start faster than 0.1 seconds as a false start, because no one can truly react that fast.

Real driving is much slower than any screen test. Road safety guides often assume 1 to 1.5 seconds, because a driver must notice a hazard, decide what to do and move a foot to the brake.

How to find your own average

One run of five rounds is a snapshot, not your true average. For a fair number, play three runs at different times of day on the same device, then look at the middle result.

Skip the first run after you wake up or come back from a break, since your hands are still cold. Your history panel keeps every run on this device, and you can download it as a file to track changes over weeks.
