Keyboard Polling Rate Test

Hold any key for 3+ seconds. We sample the auto-repeat interval.

Press and HOLD any key for 3+ seconds. The tool measures the OS auto-repeat rate, which approximates your keyboard polling Hz.
Note: Browser key events are throttled by OS auto-repeat settings (typically ~30 events/sec on Windows). True keyboard polling Hz is measured by the firmware before OS, but this gives a useful comparative reading between keyboards on the same OS.

What Is a Keyboard Polling Rate Test?

A keyboard polling rate test measures how often your keyboard reports its state to the computer, expressed in Hz (samples per second). A 1000Hz keyboard reports every 1ms. A 125Hz keyboard reports every 8ms. Higher polling rate = lower input latency.

This browser-based test estimates polling rate by measuring the OS auto-repeat interval when you hold a key. Important caveat: browsers do NOT receive raw USB polling events — the OS throttles auto-repeat to about 30 events per second by default. So this tool measures the OS-imposed ceiling rather than the keyboard's true firmware polling rate.

For gaming keyboards advertised as 8000Hz, the difference vs 1000Hz is invisible to this tool because both are well above OS auto-repeat throttling. But for older or budget keyboards reporting at 125Hz, a noticeably lower rate may show.

How to Read the Results

  • Avg interval: Average milliseconds between auto-repeat events. Healthy: ~30-35ms (matches OS default repeat rate).
  • Estimated rate: 1000 / avg interval. Typical reading: 28-33 Hz (OS-throttled). If much lower, your OS auto-repeat is set slow or keyboard polling can't keep up.
  • Min interval: Shortest gap between consecutive events. The closer to 1ms, the better your keyboard polling is.

What This Tool Cannot Measure

True USB polling rate beyond the OS auto-repeat ceiling needs hardware-level tools (Wireshark USBPcap, manufacturer software). For a more direct measure of keyboard responsiveness in your browser, also try our latency checker which measures end-to-end keypress-to-screen latency. If the problem is the pause before a held key repeats, follow the key repeat rate and repeat delay guide instead of chasing polling rate.

Also see mouse polling rate test which uses pointer events that ARE delivered at native polling rate (no OS throttling) and gives true 1000Hz/8000Hz readings.

Keyboard Polling Rate Test FAQ

Common keyboard polling rate test questions

What is a keyboard polling rate test?

A keyboard polling rate test estimates how quickly your keyboard input is sampled. Hold any key for 3 or more seconds and the test measures the OS auto-repeat timing, reporting live samples, the average interval, and the minimum gap between events.

Why does the test use auto-repeat timing?

Browsers cannot read the USB polling rate directly, so the keyboard polling rate test uses the OS auto-repeat interval as a proxy. The minimum gap it captures is bounded by both your OS repeat settings and how fast the keyboard delivers events, so treat the result as an estimate.

What polling rate do most keyboards use?

Standard office keyboards typically poll at 125 Hz (8 ms), while gaming keyboards commonly run at 500 or 1000 Hz (2 ms or 1 ms). Some high-end boards advertise 4000 to 8000 Hz, which browser timing cannot fully resolve.

Can I change my keyboard polling rate?

On many gaming keyboards, yes - through the manufacturer software or onboard shortcuts. Office keyboards usually have a fixed rate that cannot be changed.

Is the keyboard polling rate test free?

Yes. The keyboard polling rate test is free and runs entirely in your browser - no download or install, and keystroke timing never leaves your device.
