Reaction Time Test

Wait for the panel to turn orange, then click as fast as you can. Five rounds, averaged, with random delays so you cannot guess the timing.

Part of your score is your screen

A browser reaction test measures the whole chain: the page changes colour, your monitor waits for its next refresh and draws it, your eyes and brain react, your finger presses, and the mouse reports the click. Only one of those links is you. Play with the settings below to see how much the hardware adds.

What is actually in your reaction time?

  • You: see, decide, move 215 ms
  • Monitor refresh & scan-out 25 ms
  • Browser, OS & game loop 20 ms
  • Mouse polling 4 ms
  • Score the test would show ≈ 264 ms
A 60 Hz screen alone adds around 25 ms on average: the colour change waits for the next refresh and then has to be drawn. Going to 240 Hz saves roughly 18 ms. Polling rate matters far less for reaction tests (a 125 Hz mouse adds about 4 ms on average) but helps smooth aiming. The rest is you, and that part trains.

Reaction time ranges

AverageWhat it means
< 180 msExceptional, especially on a 60 Hz screen
180–220 msFast; common among regular gamers
220–270 msTypical adult range
270–330 msSlower; tiredness and distractions push scores here

Getting a fair score

  • Use a wired mouse and your fastest screen, and close heavy tabs.
  • Rest your finger on the button so you only need to press, not move.
  • Look at the centre of the panel, not the numbers.
  • Take the average of a few sets. Single rounds jump around by 30 ms or more.

Questions

What is a good reaction time?

For a simple visual test like this, most adults average between 200 and 280 ms. Under 200 ms is fast, and consistently under 170 ms is rare. Results include your screen and system lag, so they vary by device.

How does the reaction time test work?

Click to start, wait for the panel to turn orange, then click as fast as you can. The delay before it turns is random so you cannot anticipate it. Five rounds are averaged.

Why is my reaction time slower on this device?

The number includes display refresh, browser and input delays. A 60 Hz laptop screen adds roughly 20 to 30 ms compared with a fast gaming monitor, and wireless or Bluetooth input can add more.

Can you improve reaction time?

Somewhat. Sleep, warm-up, caffeine in moderation and practice all help a little. Most gains in games come from anticipation and game knowledge rather than raw reaction speed.

What happens if I click too early?

The round is discarded and you start it again. Early clicks are not counted in your average.
