Mouse Movement Event Rate Test
Measure browser-observed pointermove rates while moving the mouse. Not a USB polling analyzer certificate.
Tests run locally in your browser. We do not upload keystrokes, pointer paths, or media.
Important
- Browsers may coalesce or schedule pointer events. Trackpads are not equivalent to mouse hardware polling.
Start, then move the mouse inside this area.

Observed Hz is the browser-observed movement event rate. It is not a direct measurement of USB hardware polling rate.
How to use
- Open this tool and follow the on-screen Start control.
- Keep the tab focused during measurement for accurate samples.
- Review results, limitations, and related tools below.
- Use Reset to clear local trial state when available.
What the result means
- Numbers come from browser APIs and local timing only.
- See Limitations for what this test cannot claim.
Limitations
- Browsers may coalesce or schedule pointer events. Trackpads are not equivalent to mouse hardware polling.
Troubleshooting
- Nothing happens after Start
- Focus the tab, allow required permissions if prompted, and ensure the test surface receives input.

FAQ
Is this a hardware laboratory result?
No. DeviceMetrik reports browser-observed values with explicit limitations.
