What is keyboard polling rate?

A keyboard’s polling rate is how many times per second your computer asks the keyboard “any new keys pressed?” measured in Hz. A 1000Hz keyboard reports 1,000 times per second. Higher polling rate means lower input lag.

How Interval Clustering Works?

Unlike simple tap counters (which fail when human speed caps at ~15Hz), this tool uses phase-alignment scoring. It tests your event timestamps against seven candidate polling rates 125Hz through 8000Hz and finds which interval best explains the gaps between your key events.

Think of it like photographing a spinning roulette wheel at random moments. Your photo timing is random, but the wheel’s spoke pattern reveals its true speed. The algorithm does the same with keyboard timestamps the polling rate “spokes” emerge from the noise of human tapping.

Polling Rate Reference Table

Polling Rate	Interval	Latency	Gaming	Typing	Best For
125 Hz	8 ms	Noticeable	Poor	Adequate	Office, Bluetooth keyboards
250 Hz	4 ms	Slight	Fair	Good	Casual gaming, budget
500 Hz	2 ms	Minimal	Good	Excellent	Competitive gaming entry
1000 Hz	1 ms	Near-zero	Excellent	Overkill	Esports, custom mech keyboards
4000 Hz	0.25 ms	Imperceptible	Pro	Overkill	Pro esports, Hall Effect
8000 Hz	0.125 ms	Imperceptible	Elite	Overkill	Keychron Q HE, Wooting 80HE
