Mouse Rate Test Guide

How to use the mouse rate test

Move the mouse quickly and continuously around the test zone. Larger circles usually provide enough movement for the browser to deliver a representative event stream.

Understanding the results

Current and peak Hz describe pointer events delivered to the page; median interval shows their typical spacing. A flatter trace indicates more consistent delivery.

What this browser tool can measure

Browsers and operating systems may coalesce pointer events, especially on high-rate devices. The result is delivered event rate, not a direct USB analyzer reading.

Private by design

The interactive work happens locally in this browser. No account is required, and test inputs are not sent away to calculate the result.
