How to use Mouse Test

  1. 1Move the pointer into the test area.
  2. 2Press each button in turn — left, right, middle (wheel click) and the back and forward side buttons. The mouse picture lights up and the counters increase.
  3. 3Scroll the wheel up and down (and sideways if your mouse supports it) and watch the scroll counters.
  4. 4Click the left button normally a few dozen times. If a warning about unintended double clicks appears, the switch is likely worn.

Test your mouse in seconds

A mouse that double clicks on its own, a dead side button or a jumpy scroll wheel can be maddening — files open when you meant to select them, drag-and-drop fails and games misbehave. This mouse test lets you check every part of your mouse in your browser: all five standard buttons, the scroll wheel in both directions and horizontal tilt, and the most common fault of all, unwanted double clicking caused by a worn switch.

Features

  • Five buttons: left, right, middle (wheel click), back and forward side buttons.
  • Live mouse diagram that lights up the button you're pressing.
  • Press counters for each button and for double clicks.
  • Double-click fault detection: flags presses that follow each other faster than a human can click.
  • Scroll wheel counters for up, down, left and right.
  • Safe test area: no context menu, no autoscroll and no accidental back navigation.

Diagnosing a double-clicking mouse

Mouse buttons use small mechanical switches. Over time, the metal contact inside can wear or oxidize, and a single press then "bounces" and registers as two clicks a few milliseconds apart. A person can't click the same button twice in under about 80 ms, so this tool counts any pair of presses closer together than that as unintended.

If the warning appears:

  1. Repeat the test to make sure it happens consistently.
  2. Try another port or computer to rule out drivers and software.
  3. Check your system's double-click speed setting — a very slow setting turns normal clicks into double clicks in apps, though not in this test.
  4. Replace or repair the mouse if the fault continues. Many gaming mice have replaceable switches.

Checking the scroll wheel

Scroll slowly one notch at a time in one direction. The matching counter should rise steadily while the opposite counter stays still. Occasional jumps in the wrong direction usually mean dust in the wheel encoder; compressed air can help. If your mouse has a tilting wheel, push it left and right to test horizontal scrolling.

Other tests

Measure how fast you can click with the Click Speed Test, check every key with the Keyboard Test, test a touchscreen with the Touch Screen Test, or see how smooth your display is with the Refresh Rate Test.

Frequently asked questions

How do I know if my mouse is double clicking by itself?
Single-click the left button slowly 20–30 times inside the test area. Each press should add exactly one to the counter. If the tool reports unintended double clicks — two presses less than 80 milliseconds apart, faster than a person can click — the button's switch is bouncing.
How do I fix a mouse that double clicks?
First rule out software by trying another USB port, a different computer, and resetting the double-click speed in your system settings. Blowing compressed air around the button sometimes helps. A worn micro-switch usually needs replacing; mice under warranty can often be exchanged.
Why don't the side buttons register?
Browsers receive back and forward buttons on most mice, but some mouse software remaps them to keystrokes or other actions. Check your mouse software, or test on another computer. Mice with more than five buttons may send extra buttons only to their own software.
Why does the counter go up by more than one when I scroll?
Each notch of the wheel normally sends one scroll event, but smooth-scrolling wheels, free-spin wheels and touchpads send many small events. That's normal. Jumping in the wrong direction, however, points to a dirty or failing wheel encoder.
Will this test open menus or go back a page?
No. Inside the test area the right-click menu, middle-click scrolling and back/forward navigation are blocked so you can test those buttons freely.
Does it work with touchpads?
Yes. Taps and clicks count as left clicks, two-finger clicks usually count as right clicks, and two-finger swipes count as scrolling.
