What Is a Good Reaction Time?
Learn how to interpret reaction time results, common average ranges, fast scores, and device latency.
Common interpretation
Simple visual reaction results often land around 200-300ms. Around 200ms is fast, and below 180ms is very sharp. A 5-round average and recent trend are more useful than a single lucky attempt.
Why hardware changes results
Refresh rate, display response, mouse or touch latency, and browser load can all affect millisecond scores. The same person may score differently on a desktop, phone, or trackpad.
How to read Testier results
Testier shows averages, best and worst attempts, and recent score trends. Tiers are a friendly comparison tool, not an official certification of ability.
