Mouse Polling Rate Test
An observational diagnostic tool that measures high-resolution event intervals, observed report frequency, and browser-level dispatch timing.

Mouse Polling Rate & Event Interval Inspector
Keep the cursor moving continuously. The script captures high-resolution timestamps via performance.now().
Nominal Hardware Polling Interval Reference Table
Theoretical standard| Hardware Polling Rate | Nominal Interval | Common Tier |
|---|---|---|
| 125 Hz | 8.00 ms | Office / Standard USB |
| 250 Hz | 4.00 ms | Budget Wireless |
| 500 Hz | 2.00 ms | Legacy Gaming |
| 1000 Hz | 1.00 ms | Esports Standard (1 kHz) |
| 2000 Hz | 0.50 ms | High-Speed Wireless (2 kHz) |
| 4000 Hz | 0.25 ms | Ultra Gaming (4 kHz) |
| 8000 Hz | 0.125 ms | Extreme 8 kHz |
2. How Event Timing Is Measured
The browser listens for high-speed pointermove DOM events. On every packet arrival, the script calculates the delta timestamp (Δt) in milliseconds using the browser's monotonic high-resolution clock (performance.now()).
3. Browser Throttling vs Hardware Polling
Why Browsers Disclose Observed Timing
Browsers are designed to optimize battery life and render performance. Unless your browser specifically implements getCoalescedEvents(), it will merge multiple rapid USB packets into a single DOM event that fires once per display frame. A reading of ~144 Hz or ~240 Hz on a 1000 Hz mouse reflects display-synchronized event coalescing, not a malfunctioning mouse.
4. Interpreting Interval Milliseconds
- ~1.00 ms minimum interval: Indicates true 1000 Hz packet delivery is successfully reaching the browser.
- ~0.25 ms minimum interval: Indicates high-speed 4000 Hz gaming mouse transmission.
- ~6.94 ms to ~16.6 ms intervals: Indicates browser event coalescing matching a 144 Hz or 60 Hz display refresh cycle.
Polling Rate Test FAQ
Common questions about browser-observed report rates.
Why is my 1000 Hz mouse showing ~144 Hz or ~240 Hz in the browser?
How can I measure my true 1000Hz or 4000Hz hardware polling rate without browser limits?
