Reaction Time Test
Wait for the screen to turn green, then click (or tap) as fast as you can. Measured in milliseconds over 5 rounds. How do you compare to the human average of 250 ms?
What Is Reaction Time?
Reaction time is the elapsed time between a stimulus (the screen turning green) and your motor response (clicking). It is composed of neural processing time, muscle activation time, and mechanical delay. The average human visual reaction time is approximately 200–300 ms, with the global average hovering around 250 ms.
Factors that affect your reaction time include fatigue, caffeine intake, age, fitness level, and practice. Gamers, athletes, and pilots tend to have below-average reaction times because of intensive training. Research shows reaction time peaks in your early twenties and gradually increases with age.
This test uses 5 rounds and calculates your average, best, and worst times. Your all-time best is saved in your browser via localStorage so you can track long-term improvement.
