What is a good reaction time?

A number with context
Reaction time is the interval between a signal appearing and your response. It is influenced by attention, anticipation, fatigue, the display, the input device, and the way a test is designed.
There is no single score that defines a person. A useful benchmark is one that you can repeat under similar conditions and compare with your own previous attempts.
How to get a more useful reading
Use the same browser and input device, remove distractions, and take several attempts instead of trusting one unusually fast or slow round. Our Reaction Time Test uses five rounds so you can see a small personal sample rather than a single click.
