Mouse Polling Rate Test

Move your mouse over the pad and see how often your browser receives position updates. The result approximates your mouse polling rate in hertz (Hz).

Browsers decide how pointer events are delivered. Chromium browsers expose every mouse sample; others deliver one event per frame. The tool tells you which applies to you.

How to use the Mouse Polling Rate Test

  1. Move your mouse onto the pad.
  2. Move it quickly and continuously, in fast circles, for three to five seconds.
  3. Watch the current, average and peak Hz readings settle.
  4. Press Reset and repeat to confirm. Try Chrome or Edge for the most accurate reading.

Understanding your results

Current Hz is based on the time between your most recent movement events, Average Hz covers the whole session and Peak Hz is the highest steady reading. The tool also shows the closest standard polling rate: 125, 250, 500, 1000, 2000, 4000 or 8000 Hz.

What is mouse polling rate?

Polling rate (also called report rate) is how many times per second your mouse reports its position to the computer, measured in hertz. A mouse at 125 Hz reports every 8 milliseconds; at 500 Hz every 2 ms; at 1000 Hz every 1 ms; and at 8000 Hz every 0.125 ms.

Why polling rate matters

A higher polling rate means the cursor moves in finer, smoother steps and your input reaches the game sooner. Going from 125 Hz to 1000 Hz is a noticeable improvement in smoothness for fast aiming, which is why gaming mice default to 1000 Hz. Beyond 1000 Hz the gains are smaller and depend on a powerful system and a game that can use them — high rates also increase CPU load.

How to read your result

  • Close to 125, 500 or 1000: that is probably your mouse's real setting.
  • Close to 60, 120, 144 or 240: you are likely seeing your display's refresh rate, because your browser reports one event per frame. Try Chrome or Edge.
  • Fluctuating widely: keep the movement continuous; pauses and slow movement skew the reading.

How to change your mouse polling rate

Most gaming mice let you pick a polling rate in the manufacturer's software or with a button on the underside. Choose 1000 Hz for a good balance of smoothness and performance. See our guide, what is mouse polling rate?

Tips to improve

  • Use a wired connection for the most reliable report rate.
  • Close heavy background apps — they can disturb event timing.
  • Test in more than one browser to see the difference in how events are delivered.

Frequently asked questions

No. It is an estimate based on what your browser reports. It is best in Chromium browsers, which expose every mouse sample.

They deliver one pointer event per frame, so the reading tracks your display refresh rate rather than the mouse itself.

It is smoother, but returns diminish beyond 1000 Hz and higher rates use more CPU.
