The Reaction Speed Test measures how quickly you respond to a visual stimulus. Your brain processes the green signal and sends a command to your hand — the entire chain takes time. Elite athletes and gamers typically react in under 200ms.
Frequently Asked Questions
What is a good reaction time?
The average human reaction time is around 250ms. Under 200ms is excellent — top 5% globally. Under 150ms is exceptional and rare outside of professional gamers and athletes.
What is the average reaction time?
Most people score between 230ms and 280ms. Factors like age, fatigue, caffeine and screen brightness all affect your time.
How can I improve my reaction time?
Practice regularly, stay hydrated, get enough sleep, and avoid alcohol. Gaming and sports that require fast responses also help over time.
Why do I sometimes click too early?
Anticipation — your brain predicts when it will turn green instead of reacting to it. True reaction tests use random delays to prevent this.
