Keyboard Polling Rate Test
Measure keyboard polling frequency and key event interval timing in your browser. Test peak observed Hz, average keystroke intervals, and event consistency.
A keyboard polling rate test measures how frequently your keyboard transmits keystroke state changes to your computer in Hertz (Hz). Most gaming keyboards poll at 1000 Hz (1 ms interval), while ultra-high-speed magnetic switch boards reach 8000 Hz (0.125 ms).
Keyboard Event Polling Rate
Press and hold any key on your keyboard to test the event frequency.
What Is Keyboard Polling Rate?
Keyboard polling rate defines the USB frequency at which the keyboard microcontroller sends matrix state updates to your PC. A standard office keyboard operates at 125 Hz (reporting every 8 ms), while gaming keyboards poll at 1000 Hz (1 ms) or up to 8000 Hz (0.125 ms).
Higher keyboard polling rates reduce input delay between the physical bottom-out of a key switch and your character executing movement or abilities in-game.
When combined with modern Hall Effect magnetic analog switches featuring Rapid Trigger, high polling rates provide near-instantaneous counter-strafing in games like Valorant and Counter-Strike 2.
How to Test Keyboard Polling Rate
Click inside the test container to capture keyboard events.
Rapidly vibrate two adjacent fingers between keys like 'Z' and 'X' or 'J' and 'K'. Alternating distinct keys avoids OS typographical repeat limits.
Holding down a single key triggers Windows typographical repeat delay (capped at ~30 Hz). Rapid alternating presses test true USB event burst timing.
Watch peak observed frequency (Hz) and sub-millisecond interval timestamps update in real time.
Inspect peak Hz, shortest interval in milliseconds, and matrix delivery consistency.
How to Read Your Results & Performance Benchmarks
Compare your observed diagnostic measurements against verified hardware standards.
| Polling Rate | Interval (ms) | Switch Technology | Gaming Benchmark |
|---|---|---|---|
| 125 Hz | 8.0 ms | Standard Membrane / Bluetooth | Noticeable input delay; fine for typing, unsuited for fast rhythm games. |
| 500 Hz | 2.0 ms | Standard Mechanical | Good responsiveness; minimal CPU load. |
| 1000 Hz | 1.0 ms | Esports Benchmark Mechanical | Tournament standard for CS2, Valorant, osu!, and rhythm games. |
| 8000 Hz | 0.125 ms | Hall Effect / Magnetic Switches | Instantaneous counter-strafing and Rapid Trigger responsiveness. |
Keyboard Polling Rate Troubleshooting
Cause: Holding down a single key activates Windows typographical autorepeat, which is intentionally throttled by the OS.
Cause: Standard Bluetooth HID profiles are bandwidth-capped at 125-133 Hz for power saving.
Browsers receive keydown and keyup events after they pass through the OS keyboard filter driver and window message queue. While high-frequency alternating keystrokes reliably capture peak burst speeds, observed browser event timing includes OS thread scheduling latency.
