How to Test Your Reaction Time
Select Visual, Audio, or Reflex mode depending on which aspect of reaction time you want to test.
In Visual mode, wait for the screen to turn green and click immediately. In Audio mode, click when you hear the beep. In Reflex mode, click targets as they appear.
After several attempts, check your average reaction time, rank, percentile, and gaming context to see how you compare.
FAQ
What is a good reaction time?
Average human reaction time is around 200–250ms. Competitive gamers typically score 150–200ms. Anything under 150ms is considered exceptional and puts you in the top percentile.
Why is my audio reaction time different from visual?
Auditory signals are processed faster by the brain than visual ones. Most people react 20–40ms faster to sound than to a color change. This is a normal neurological difference.
Can I improve my reaction time?
Yes. Regular practice, adequate sleep, physical exercise, and reducing screen fatigue can all improve reaction speed. Caffeine may also provide a temporary boost. Professional gamers train daily with reaction drills.
Does hardware affect my results?
Yes. Monitor refresh rate, input lag, and mouse polling rate all add latency. A 60Hz monitor adds up to 16ms of delay compared to a 240Hz display. For the most accurate results, use a low-latency setup.
How many attempts should I do?
At least 5 attempts are recommended for a reliable average. Your first 1–2 attempts may be slower due to unfamiliarity. The median score is often more representative than the average since it ignores outliers.
