What is a good reaction time?
For a simple visual test like this one, many adults score somewhere around 200–300 milliseconds. Under 200 ms is fast; elite gamers and athletes often sit in the 150–200 ms range. Your device matters too: screens, mice and touchscreens add delay.
How to get a faster score
- Use a mouse or keyboard (press space) instead of a touchscreen.
- Sit close, relax your hand, and stay focused on the box.
- Get enough sleep. Tiredness and caffeine withdrawal both slow reactions.
The percentile shown is a rough estimate based on a typical spread of simple reaction times, not a scientific measurement.
FAQ
What is the average human reaction time?
For simple visual reaction tests, most people land roughly between 200 and 300 milliseconds, with the middle around 250–275 ms. Results vary with device and age.
Why is my score slower on my phone?
Touchscreens and some displays add input and display delay, often 20–60 ms. A wired mouse and a fast monitor give lower numbers.
What happens if I click too early?
Clicking before the screen turns green counts as a false start and that round is repeated.
