Browser mouse test

Test your mouse buttons and scroll

Click inside the test area to check each mouse button. Scroll over the area to test both wheel directions. Pressed inputs light up in yellow; tested inputs stay highlighted.

How to use the mouse test

The page records the inputs your browser receives. It does not install a driver or change your mouse settings, so it is a quick way to check whether a button or scroll direction is reaching the page at all.

  1. Open the test area. Click inside the test panel, then press each mouse button one at a time. The matching part of the mouse graphic lights up while the button is held.
  2. Check each button. Test the left, right and middle buttons first. If your mouse has back and forward buttons, test those separately.
  3. Test both scroll directions. Scroll up and down over the test area. The up and down indicators light up, and the status list records which direction registered.
  4. Read the results. A tested input stays highlighted and shows its click or event count. A button that never changes state did not reach the browser.
  5. Reset and repeat. Use the reset button to clear the results and run the test again. Repeat any suspicious button a few times before drawing a conclusion.

What the test checks

  • Left, right and middle mouse buttons.
  • Back and forward side buttons where your browser exposes them.
  • Scroll wheel movement in both directions.
  • Whether a single press produces more than one click event.

The click count beside each button is useful for spotting a switch that is starting to chatter. A normal press should add one count. If a single press repeatedly adds two, test the mouse on another device and check whether it is still under warranty.

What this test cannot detect

  • Whether your mouse sensor tracks accurately.
  • Your actual DPI or CPI value.
  • Polling rate, input latency or wireless stability.
  • Game-specific bindings, macros or profiles that never reach the browser.
  • Every hardware fault; a button can work intermittently.

For sensor accuracy, use the DPI analyzer. For input behavior inside a game, read the raw input and mouse acceleration guide.

If a button or scroll direction does not register

  1. Test the same mouse in another browser to rule out a browser-specific issue.
  2. Open your mouse software and check whether the button is remapped or disabled.
  3. Try another USB port, cable or wireless receiver.
  4. Close software that intercepts mouse input, then reload the page.
  5. Test another mouse to see whether the problem follows the device.

A side button that is assigned to a keyboard shortcut or a macro may never appear as a mouse button on this page. That is expected behavior, not necessarily a hardware failure.

Mouse test vs DPI analyzer

A mouse test checks whether buttons and scroll directions register. A DPI analyzer measures how many counts the mouse reports over a known distance. They answer different questions: one is about input registration, the other is about sensor scale.

If both tests look correct but your aim still feels inconsistent, read mouse DPI explained and raw input and mouse acceleration before changing your sensitivity.

FAQ

How do I test my mouse buttons?

Click inside the test area and press each mouse button one at a time. A working button lights up while pressed and stays highlighted as tested after release.

How do I test my scroll wheel?

Scroll up and down over the test area. The matching arrow lights up while scrolling, then stays highlighted as tested.

Why does a side button not register?

Many mice let you remap side buttons, and some browsers or operating systems consume those inputs before the page sees them. Check your mouse software and try another browser before assuming the switch has failed.

Does this test detect double-click problems?

The click counter helps. If one physical press adds two counts, the switch may be chattering. That is a useful signal, but it is not a definitive hardware diagnosis.

Can I use this mouse test on a phone or touchscreen?

No. Touch input does not report mouse buttons or a scroll wheel. Use a desktop or laptop with a mouse.

Is any data sent when I use the test?

No. The test runs entirely in your browser. It does not send button presses, scroll events or results anywhere.

What if a button works in a game but not here?

The browser may not receive an input that a game receives through a different input path. Check mouse software, browser permissions and remapping, then compare with the raw input guide. Read about raw input and mouse acceleration

Next step: check your DPI

If your buttons and scroll wheel register correctly, measure your actual mouse DPI next. The result can be used directly in the sensitivity converter.
