Mouse Test Online

Check mouse clicks, pointer movement and scrolling in one simple testing area. Useful for a USB mouse, wireless mouse or trackpad.

Mouse result & next steps

Test your device above, then review what the browser actually confirmed. A connected device is not the same as a certified working device.

Ready for testing

No result yet. Start the test above.

  • Move inside the test pad and check that the movement count changes.
  • Test left, right and middle clicks, then scroll the wheel.
  • If browser events work but an app does not, check that app settings and permissions.

How do I test my mouse buttons and scroll wheel?

Quick answer

Move your pointer around the test area, click each button and scroll. The browser counts movement, button and wheel events, helping you check whether inputs reach the webpage.

How to run this test

  1. Move the pointer inside the mouse test area.
  2. Click the left, right and middle buttons to observe events.
  3. Scroll up and down over the test area.
  4. Repeat a problematic action several times to check consistency.
  5. Reset the counters and compare with another mouse if needed.

Understanding your result

✓ What a good result looks like

Mouse movement, expected buttons and wheel actions produce corresponding events in the tester.

! If something does not work

Some buttons are mapped to system actions or intercepted by browser settings; the browser cannot measure switch wear directly.

Troubleshooting common problems

Clicks are not detected

Try another USB port or reconnect Bluetooth, then test whether clicks work in the operating system.

Scroll is not detected

Move the cursor over the test area while scrolling; check mouse software and pointer settings.

Unexpected double-clicks

Compare using another mouse or check accessibility settings. Repeated unexpected events may indicate a worn switch.

What this browser test cannot prove: This measures browser pointer events rather than physical switch travel, accurate DPI, polling rate or calibrated click latency.

Frequently asked questions

Can I test right-click online?

Yes. Right-click in the designated area; the tester detects the button event and suppresses the normal context menu there.

Does it detect a mouse wheel?

It counts wheel events received over the test region.

Can I measure mouse DPI?

Not accurately with this test. Browser pointer movement is influenced by operating-system settings and acceleration.

Will it work with a trackpad?

Movement and some clicks may work. Gestures and event mapping depend on the device, OS and browser.
