Keyboard latency & input lag guides

Understand input delay, polling, and jitter in plain language—then measure your setup with our browser keyboard latency tester before you compare timed typing scores.

Free tool

Sample keyboard input lag in your browser

Press keys naturally—we measure keydown-to-paint time in this tab. Useful for comparing setups, not raw USB oscilloscope numbers.

  1. Step 1

    Focus the test area

    Click the keyboard box so key events and paint timing register.

  2. Step 2

    Press keys naturally

    Type a few letters—avoid held keys and modifier shortcuts.

  3. Step 3

    Review latency samples

    See average, spread, and band guidance before a timed WPM run.
