How to use the Mouse Polling Rate Test accurately
Free open source mouse polling rate test online. Check if your gaming mouse runs at 125Hz, 500Hz, 1000Hz or higher. Move your mouse to see live Hz readings. No download needed.
01What Is Mouse Polling Rate?
Mouse polling rate is how frequently your mouse sends position data to the computer, measured in Hz (reports per second). At 125Hz it reports every 8ms. At 1000Hz, every 1ms. At 8000Hz, every 0.125ms.

Quick reference
03Why Does My Mouse Show Lower Than Expected Hz?
Browser-based tests measure the Hz your browser receives, which may be 10–20% lower than hardware polling rate due to JavaScript event processing overhead and OS input scheduling.
04How to Change Mouse Polling Rate
Settings guide
A mouse polling rate test measures how many times per second your mouse reports its position, in Hz. Click Start and move the mouse in steady circles inside the test area to see the live Hz reading, the average, the peak, and the total sample count.
What is a good mouse polling rate?
Office mice typically poll at 125 Hz, which is fine for desktop work. Gaming mice standardize on 500 or 1000 Hz for smoother tracking, and newer gaming mice can reach 2000 Hz or higher.
Why does my mouse show a lower Hz than advertised?
Slow or small movements generate fewer events, and browsers can coalesce input events under load. Move the mouse quickly in large continuous circles and treat the peak Hz as the closest indicator of the true polling rate.
How do I change my mouse polling rate?
Gaming mice usually expose the setting in their companion software, and some have a dedicated switch on the underside. Office mice generally run at a fixed 125 Hz that cannot be changed.
Is the mouse polling rate test free?
Yes. The mouse polling rate test is free, runs in your browser with no download, and all measurement happens locally on your device.
