Frequently Asked Questions

What is a good reaction time?

A good reaction time is between 200–250ms. The average person scores around 250–270ms. Elite gamers and athletes often score below 200ms. Anything under 150ms is exceptionally rare.

How can I improve my reaction time?

Regular practice is the most effective way. Playing reaction-based games, getting enough sleep, regular physical exercise, and staying hydrated all contribute to faster reflexes. Consistent training over weeks shows measurable improvement.

Does reaction time slow down with age?

Yes. Peak reaction speed typically occurs between 18–24 years. After 30, reaction time gradually increases by a few milliseconds per decade. However, regular brain training and physical activity can significantly slow this natural decline.

Is this reaction time test accurate?

Our test measures milliseconds between the visual stimulus and your click/tap. Results are consistent enough to track your progress over time. Minor variations may occur depending on your monitor refresh rate and device hardware.
