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.
Step 1
Focus the test area
Click the keyboard box so key events and paint timing register.
Step 2
Press keys naturally
Type a few letters—avoid held keys and modifier shortcuts.
Step 3
Review latency samples
See average, spread, and band guidance before a timed WPM run.
No download or sign-in. Compare wired, Bluetooth, or another machine in minutes.

Keyboard Polling Rate vs Latency for Typing Scores: Hz, Milliseconds, and Honest Benchmarks
Polling rate in Hz is not end-to-end latency. Learn how each shows up in typing benchmarks, why Bluetooth can spike delay at high Hz, and how to pair the latency lab with a one-minute test.
