What is the Reaction Time Test?
How It Works
Wait for the screen to turn green, then click as fast as possible. The test measures the delay between the visual stimulus and your response in milliseconds.
Average Reaction Time
The average human reaction time is 250–300 ms. Gamers and athletes often achieve 200–250 ms. Under 200 ms is considered excellent.
Tips to Improve
Stay focused, avoid anticipating the green (which causes false starts), get enough sleep, and practice regularly. Reaction time improves with consistent training.
FAQ
Why did I click too early?
Anticipating the stimulus — wait until you actually see green.
Is 150 ms possible?
Extremely rare without false starts; 180–220 ms is more realistic for trained users.
What is a good reaction time?
Under 250 ms is above average; pro gamers often hit 200 ms.
How many tries should I do?
Take 3–5 attempts and use your best valid score for a fair comparison.
