Mouse Polling Rate
Measure your mouse's polling rate in Hz. Run the browser-based check and follow its prompts to review the result.
Both external mice and trackpads can produce results. Browsers usually report both as a mouse pointer, so this tool cannot tell which device you used or read its true hardware polling rate. It counts movement events delivered by the browser; operating system settings, browser event coalescing, and how steadily you move can affect the estimate.
Tool guide
About Mouse Polling Rate Checker
Estimate pointer event frequency from movement events delivered to the browser. The number can be affected by the mouse, operating system, browser, display, and how steadily you move.
How to use this tool
- 1Connect the mouse or trackpad you want to check and move the pointer inside the test area.
- 2Keep moving for the measurement interval so the tool receives enough pointer events.
- 3Read the estimated rate and event count, then compare devices under similar movement conditions.
How the tool works
The page counts pointer movement events and estimates event frequency over elapsed time. Browser event coalescing and operating-system scheduling mean this is not a direct USB report-rate measurement; a stationary mouse produces no movement events.
Worked real-world example
A device advertised at 1,000 Hz may show a lower browser estimate because events can be grouped or dropped before reaching the page.
Common scenarios and use cases
Get a rough browser-level comparison of pointer responsiveness or confirm movement events are arriving.
Important details and limitations
This does not inspect the USB polling signal or guarantee a device's rated rate. Trackpads, wireless power saving, browser load, and movement speed all change the estimate.
Check the output unit as well as the number. If the result will be reused in another calculation, retain full precision where possible and round only at the end. For measurements governed by a technical specification, use the standard and tolerance required by that document.
Frequently asked questions
Is the displayed rate the exact USB polling rate?
No. It estimates browser pointer events.
Why do I need to move the mouse?
The page measures movement events; no movement means there is nothing to count.
Can a trackpad be tested?
Yes, but its event behavior differs from a mouse.
