Keyboard Latency & Reaction Test

Measure your system latency and physical reaction time. High WPM requires low latency mechanical keyboards.

What is a good Keyboard Reaction Time?

The average human visual reaction time is around 250ms. However, the score you see above is your **total system latency**. It includes:

  • Human Reaction: ~200-250ms
  • Keyboard Polling Rate: 1ms (1000Hz gaming keyboard) to 15ms (bluetooth keyboard)
  • Switch Actuation: Time taken for the mechanical switch to travel down (1-3ms)
  • Monitor Input Lag & Refresh Rate: 5-20ms depending on your Hz.

If you are consistently scoring below 200ms, you have exceptional reflexes and likely a high-end mechanical keyboard. Competitive typists typing at 150+ WPM rely on keyboards with sub-2ms latency to avoid input desync.
