Mouse Test

Press every button and scroll in every direction inside the box. Each button lights up when it registers, and two presses closer together than the limit you choose are flagged as a possible double-click fault.

Double-click fault limit:

Click anywhere in this box with each button, and scroll up, down and sideways (tilt the wheel if it can).

This mouse test checks that every button and the wheel register, and catches double-click faults. Each press is timed, so the log shows how long you held the button and how long it was since the last press of the same button. Presses that come closer together than the limit you choose are flagged.

How to Run the Test

  1. Press left, right, middle (the wheel), back and forward once each. Every button should light up.
  2. Click each main button slowly about twenty times, one deliberate click at a time.
  3. Check the Flagged column. On slow single clicks it should stay at 0.
  4. Scroll up and down, then tilt the wheel left and right if it tilts.

Reading the Results

What you seeWhat it means
A button never lights upIt is not sending a press: broken, or remapped in the mouse software
Flags on slow single clicksOne press arriving twice: the switch is likely worn
Flags only when you click fastProbably your own double-click. Try the 30 ms limit
Released after a few ms on a held pressThe switch is losing contact while held, which also breaks dragging
Scroll counts in the wrong directionSee the scroll wheel test for backward steps

Why the Limit Is Adjustable

There is no single standard. Testers we compared flag gaps under 30 ms, 50 ms or 80 ms. A fast, deliberate double-click by a person rarely gets close to 30 ms, while a bouncing switch often sends its second press within a few milliseconds. The fastest gap per button shows the closest two presses you made, so you can see how near the limit you were.

Mouse Test or Click Speed Test?

This page checks whether the hardware works. To measure how fast you can click, use the click speed test. To see how often the mouse reports its position, use the polling rate test.

Mouse Test Questions

How do I test if my mouse buttons work?

Press each button inside the test box. Left, right, middle, back and forward each light up on the diagram and get a count. A button that never registers is either broken or remapped in the mouse's software.

What is a double-click fault?

A single press that the computer receives as two. It usually comes from a worn switch whose contacts bounce. In the test it shows as a second press only a few milliseconds after the first.

Which limit should I choose: 30, 50 or 80 ms?

Online testers use all three. 50 ms is a middle setting. If you get flags on 80 ms but not 50 ms, check whether you were clicking fast on purpose; repeated flags at 30 ms on slow single clicks point strongly to a faulty switch.

Why do back and forward buttons not show up?

Some mouse software remaps them to other actions, and some browsers use them for navigation before the page sees them. The test blocks navigation where the browser allows it. If they still do nothing, check the mouse's software.

Does this work for wireless and Bluetooth mice?

Yes. The browser sees the same button events from wired, wireless and Bluetooth mice.

Can I fix a double-clicking mouse?

If the mouse is under warranty, contact the maker. Otherwise the switch can be replaced, which needs soldering. A software setting cannot repair a worn switch.

Is anything uploaded?

No. The test runs in your browser and nothing about your clicks is sent or stored.
