Reaction Time Test
What's a good reaction time?
- < 200 msExceptional - esports-level reflexes
- 200-249 msFast - quicker than most people
- 250-309 msAverage - a typical reaction
- 310-379 msA bit slow - tired or distracted?
- 380+ msSlow - try again when you're fresh
Times include your screen's and mouse's own lag, typically 10-40 ms, so the same person scores a little slower on an older monitor or a wireless mouse. Phones' touchscreens add more.
How fast are your reflexes? Click when the screen turns green - or when you hear a beep - five times, and see your average, best and rating in ms.
Test how quickly you react. Click to start, wait for the box to turn from red to green, and click as fast as you can; after five tries you get your average, median, best time and a rating. Switch to sound to measure how fast you react to a beep instead - most people are faster to sounds. Clicks are timed from the moment they happen with the browser's high-resolution clock, and clicking before the signal counts as too soon. Your best average is remembered on this device only.
