Reaction speed explained
What is a good reaction time?
Most people score between 250 and 300 milliseconds on a visual reaction time test. A lower number means a faster response, but your score can change with sleep, attention, display refresh rate, input device, and network or browser performance. Run the test a few times in the same setup to get a more useful personal baseline.
This reaction time test is designed for quick self-benchmarking and entertainment. It is not a medical, neurological, or clinical assessment. For the fairest result, use a desktop mouse, keep your hand near the test panel, and wait for the panel to turn green.
