Mouse test

Press each mouse button inside the box, scroll both ways, then measure your polling rate. Everything runs in your browser.

This test needs a computer and a mouse

Phones and tablets don't report mouse buttons or a polling rate. You can test how fast you tap instead.

Two presses of the same button less than 80 ms apart. It only points to a fault if it shows up again in 2–3 tests.

A reverse jump is a step the wrong way while you scroll in one direction. A few in a row point to a dirty or worn wheel.

Questions

How do I check if my mouse double clicks?

Click each button 20 to 30 times at a normal pace. If "Possible double click" shows up again in 2–3 tests of the same button, the switch is probably worn.

My mouse is rated 1,000 Hz. Why does the test show less?

Check the polling rate setting in the mouse software first. Wireless mice may lower it to save power, and some browsers deliver fewer events than the mouse sends.

Does a higher polling rate make me faster?

It shortens the gap between reports: at 125 Hz the mouse reports every 8 ms, at 1,000 Hz every 1 ms. Going from 125 to 1,000 Hz saves up to 7 ms. Going above 1,000 Hz saves less than 1 ms more.

Why can't I test a mouse on my phone?

Phones and tablets don't pass mouse buttons, the wheel or a polling rate to web pages in the same way. Use a computer with the mouse plugged in.

Is anything installed or uploaded?

No. The test reads the clicks, scrolls and movement your browser already receives, and nothing leaves this page.
