Reaction Time Test
Test your visual reaction time. Click when green. Tracks best and average across attempts.
Updated May 2026
Average human visual reaction time is ~250ms. Includes browser input lag (~5–20ms) and your monitor refresh (8.3ms on a 120Hz display). For a true neuroscience baseline, use a dedicated reaction-time device — but this is fine for relative comparison.
