How does your reaction time compare to people your age?

Under 200ms is fast by any standard, and it's quicker than the cohort average this calculator uses for every age group. Where you land depends on your age and sex, so the result above ranks you against your own band. Professional esports players land at 150 to 180ms on simple visual reaction time, though their real edge in a match comes from anticipation and pattern recognition rather than raw reflex speed.

Swings of 30 to 60ms between trials are normal, and they track moment-to-moment shifts in attention, arousal and motor readiness. Distraction between trials, fatigue over a longer session and a hand that moves position all feed into it. Research protocols take the mean of 5 to 20 trials to smooth the noise out, then discard anything over 1500ms or under 100ms as an outlier.

A little, and less than the internet promises. Action gaming sharpens visual attention (Green & Bavelier, 2003), aerobic exercise tracks with faster RT at every age, and caffeine lends a temporary 5 to 15ms by raising alertness. One bad night under 6 hours of sleep costs 20 to 50ms in the other direction. Nerve conduction sets a hard floor at roughly 120 to 140ms on the fastest possible pathway, so a score under 150ms means you anticipated rather than reacted.

Because the figures that circulate online mostly come from sites such as Human Benchmark, whose testers choose themselves rather than being sampled from the population. Representative samples read slower. Der and Deary (2006) reanalysed 7,130 UK adults and found simple reaction time barely slows until around 50, then climbs, while Silverman's meta-analysis of 15,003 people found men a little quicker than women. Reaction time by age bracket and stimulus type sits on the body statistics page.

Yes, though the average hides how much room there is inside it. Simple reaction time barely slows until around 50 and declines faster after that, while choice reaction time slows throughout adult life (Der & Deary, 2006). A fit, cognitively active 60-year-old will often out-react a sedentary 30-year-old. Exercise, sleep and mental engagement all slow the slide in longitudinal data, so the age band you sit in sets an expectation rather than a ceiling.

Yes, on simple visual reaction time. Silverman's 2006 meta-analysis of 72 effect sizes from 21 studies, 15,003 people in all, found men quicker. Why is still argued over, with motor neuron conduction velocity, muscle contraction speed and differences in sports or gaming exposure all proposed. The gap is small enough to go unnoticed in ordinary life and only starts to count where milliseconds decide something.

Sleep is the biggest lever of the lot. One night of fewer than 6 hours can add 20 to 50ms. Caffeine takes 5 to 15ms off for the 2 to 4 hours after you drink it, alcohol adds 30 to 50ms even at low blood levels, and antihistamines, benzodiazepines and some antidepressants slow things considerably. Time of day pulls too, with most people quickest in the late morning and slowest in the early afternoon, following the circadian alertness cycle. Cardiovascular fitness in particular tracks with faster RT.

Pros score 150 to 180ms on simple visual reaction tests, well ahead of the cohort averages this calculator uses. Their advantage in an actual match comes far more from anticipation, pattern recognition and game-specific decision speed than from raw neurology, and that is the part years of play builds. Score under 200ms here and your basic reflexes already sit where a casual competitive gamer's do.

It correlates with general intelligence at around r=0.20 to r=0.30 in large studies, which is real and far too weak to say anything about one person. Read RT as a measure of neural processing efficiency instead. Clinically, a sudden unexplained slowing can flag concussion, a sleep disorder or neurodegenerative change, and trial-to-trial inconsistency is a stronger marker than mean RT for ADHD and early cognitive decline. This test is built for benchmarking, not diagnosis.

To stop you anticipating. The gap between warning and stimulus varies from 200 to 2000ms, and without that variation you would learn the rhythm and click on schedule, which measures timing estimation and tells you nothing about reaction. Variable foreperiods are standard in research protocols for exactly this reason. Any click before the box changes is flagged as a false start and that trial reruns, so a run of false starts means you are guessing the moment instead of responding to it.
