What Is a Reaction Time Test?

A reaction time test measures elapsed time between a visual stimulus and your response, in milliseconds (ms). Our test runs 5 rounds and shows your average, best, and a rating vs global benchmarks.

How to Improve Reaction Time

  • Sleep 7–9 hours — one bad night adds 30–80ms
  • Daily practice — 10–15 min/day builds speed in 2–4 weeks
  • Play FPS games — CS2/Valorant players react 50–100ms faster
  • Caffeine — 100–200mg cuts reaction time by 10–30ms
  • 144Hz monitor — cuts display lag from ~8ms to ~3ms

The Science

Visual reaction involves 4 phases: photoreceptor activation (~10ms), signal transmission (~40–50ms), cognitive processing (~50–80ms), motor execution (~30–50ms). Total minimum: ~150ms. Reaction time peaks at age 18–24.

Frequently Asked Questions

Under 200ms is excellent. Pro CS2/Valorant players average 160–180ms. Average human: 200–250ms.
Yes, but mobile scores run 30–80ms higher due to touchscreen latency and 60Hz displays.
20–40ms variation between rounds is normal. The 5-round average smooths this out.
