How to test your mouse

To test your mouse, try the left button, right button, middle button and scroll wheel one by one in the test area above. This allows you to quickly see which buttons are being detected correctly, whether the scroll wheel is working and whether there are any clicking issues.

1. Test the left and right buttons

Check whether the main mouse buttons are detected correctly.

2. Check the middle button

Press the scroll wheel to test the middle-click function.

3. Test the scroll wheel

Scroll up and down to check whether the wheel is working properly.

Frequently Asked Questions

What does the mouse test do?

The mouse test helps you quickly check whether the left button, right button, middle button and scroll wheel are working properly.

How can I detect a double-clicking issue?

If the system occasionally detects two clicks when you click only once, the mouse may have a worn switch or a hardware-related double-clicking problem.

Why might the scroll wheel not work properly?

Dust, mechanical wear, encoder problems or software driver issues may cause the scroll wheel to behave inconsistently.

Can the left and right buttons be tested separately?

Yes. Basic mouse inputs such as the left button, right button and middle button can be checked separately during the test.

Does this test work on mobile devices?

The page can be opened on mobile devices, but the most accurate results are obtained on a desktop or laptop with a physical mouse connected.

How do you verify a suspicious result?

If you suspect one press produces two events, reset the test and press the left button individually with pauses. The mouse summary's sub-80 ms repeat counter only flags rapid events; deliberately clicking fast can increase it on a healthy mouse.

Check scrolling and connection separately

Scroll only down first, then only up. If unexpected events appear in the opposite direction, compare the same action on another page. Move a wireless receiver closer or try another USB port for a wired mouse. Change only one condition per repeat.

Browser events do not establish sensor DPI accuracy, actual polling rate or switch lifespan. Touchpad gestures can also differ from physical mouse input.
