Mouse Scroll Test

A free browser tool for testing mouse wheel scrolling. It also includes CPS, click, drag, jitter and polling rate tests. Nothing to install; everything runs in your browser.

Open mousescrolltest.com in your browser and the tool loads directly on the page. There is nothing to download or install, so you can run a check on any machine you happen to be using.

Start with the scroll test to see how your mouse wheel behaves when you turn it. From there, the same site includes a CPS test, a click test, a drag test, a jitter test and a polling rate test, so you can move between them depending on what you are trying to find out about your mouse.

This Mouse Scroll Test utilities app is useful if you suspect a wheel is skipping, a button is double-clicking, or a mouse is not reporting as often as you expect. Running a test gives you something concrete to look at before you decide whether to clean the mouse, change settings or replace it.

Because everything runs in the browser, you can come back and repeat a test later to compare, or check a second mouse on the same computer without changing your setup.
