Average Human Reaction Time

These curves are a fitted baseline plus 1 first attempt recorded here. The baseline is a curve, not a sample, so none of it is a real person and the counts below say so. Baseline fitted from Human Benchmark's published reaction time statistics (n=81,000,000) (source). That figure pools every input device into one number. Splitting it by mouse, trackpad and touchscreen is our extrapolation, not theirs. Per-device offsets are extrapolated, not measured. The baseline is dropped once a device class holds 5,000 real first attempts.

Percentile breakdown

Read a row as: to reach this percentile you need this score or better. The gap between the 50th and the 75th is usually far smaller than the gap between the 95th and the 99th, which is why small improvements move you a long way in the middle and almost nowhere at the top.

Take the reaction time test to place yourself on these curves.
