Mouse Tester
Test every mouse button, the scroll wheel and your double-click speed on a visual mouse diagram: instantly, in your browser, free.
Click, scroll and double-click inside the test area. Buttons light up as they register; if one stays dark, it is not being detected.
Double-click test
Double-click the box. Faulty switches often fire two clicks on one press: watch for double-clicks you did not make.
About Mouse Tester
The Mouse Tester checks every button on your mouse against a visual diagram: left, middle and right click, the back and forward side buttons, and wheel scrolling in both directions. Each control lights up the instant it registers; if a button stays dark while you press it, your mouse is not sending that input to the computer.
A dedicated double-click test measures the interval between your two clicks and warns when it is suspiciously short. That pattern, two clicks firing from a single physical press, is the classic symptom of a worn micro-switch, the most common mouse fault and a valid reason for a warranty claim.
Everything runs in your browser with no download and no upload. The right-click context menu is disabled inside the test area so the right button can be tested properly, and a click counter plus reset button let you run repeated checks.
How to use Mouse Tester
- Move your cursor into the test area on the page.
- Click each button (left, middle, right, back and forward) and watch it light up on the diagram.
- Scroll the wheel up and down to confirm both directions register.
- Double-click inside the double-click box and read the measured interval.
- Watch for double-clicks you did not make: they indicate a worn switch.
- Press Reset to clear the results and test again.
