How does the reaction time test work?

The test shows a red screen. Wait for it to turn green, then click as fast as you can. After 5 trials, you'll see your best, average, and median reaction time in milliseconds.

What is a good reaction time?

Average human reaction time is around 250-300 ms. Below 200 ms is considered fast, while above 300 ms may indicate slower reflexes. Use the test to see where you stand.

Can I improve my reaction time?

Yes, practice and physical fitness can help. Regular testing can track improvements. However, the test is for reference only and not a medical diagnostic tool.

Tips & Common Mistakes

Tips

Ensure you are in a distraction-free environment to get accurate results.
Use the same device and mouse/touchscreen for consistent comparisons.
Click immediately when the screen turns green, not before, to avoid false starts.
Take the test multiple times and use the average or median for a reliable measure.

Common Mistakes to Avoid

Clicking before the screen turns green, which can skew your reaction time.
Not focusing on the screen, leading to delayed clicks and inaccurate results.
Comparing your results to others without considering factors like age or fatigue.
