Quick answer
What Mouse Polling Rate Estimator tells you
Estimate browser pointer-event frequency and timing stability without claiming to measure certified USB firmware polling rate.
- Observed here
- 3, 5 and 10 second sampling, Average and median frequency, Minimum and maximum interval.
- How to interpret it
- The reported rate estimates pointermove delivery to this browser from event intervals. Browser scheduling and event coalescing can differ from the mouse USB polling rate.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Pointer positions, clicks and touch trails stay in this browser and are not transmitted.
Useful next comparison: Move continuously inside the surface during the sample and repeat in an active tab; use manufacturer tooling for hardware polling verification.
Understanding the result
What a result means
The estimate is derived from intervals between pointer events received by the page. Event coalescing, display refresh, system load and browser scheduling mean the value is not a direct USB polling-rate measurement.
Confirm the pattern by repeating 3, 5 and 10 second sampling. Results reflect events and values exposed by this browser.
How to use this test
- Choose a sample duration.
- Move the pointer continuously inside the test pad.
- Use broad, steady movements until sampling ends.
- Compare repeated results with the same browser and system load.
What this test checks
- 3, 5 and 10 second sampling
- Average and median frequency
- Minimum and maximum interval
- Timing stability chart
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
Browser coalescing, display timing and system load affect the estimate.
This is not a USB polling-rate certification.
Common problems and troubleshooting
Move continuously across a wide area for the full sample, keep the tab foregrounded and repeat with the same speed. Compare medians rather than one maximum, and use device firmware tools when an exact hardware report rate is required.
- Repeat the same observation. Focus the test surface and repeat “3, 5 and 10 second sampling” three times under the same conditions.
- Change one condition. Compare “Average and median frequency” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
Pointer-event delivery is supported across current desktop browsers, but coalescing behavior differs. High-rate mice can exceed what the rendering loop exposes, particularly on lower-refresh displays or busy systems.

Frequently asked questions
Is this Mouse Polling Rate Estimator free?
Yes. The test works without an account, download or payment.
Is my test data uploaded?
Pointer positions, clicks and touch trails stay in this browser and are not transmitted.
Does this result prove my hardware is faulty?
No. It shows what the browser can observe. Repeat the test, compare another browser or device, and seek qualified support when the result matters.
