Free Online Mouse Test

Test Your Mouse Controls

Move, click, double-click and scroll inside the live testing area to check whether your browser detects each mouse control correctly.

Pointer position

The live test shows the pointer's X and Y position inside the movement panel.

Distance moved

A running counter estimates how far the pointer has travelled inside the testing area since the test was opened or reset.

Mouse buttons

Test the left, middle and right mouse buttons. Additional buttons may also be reported when the browser exposes them.

Clicks and double-clicks

The tester counts button presses and browser-recognised double-clicks so you can look for missing or repeated input.

Scroll wheel

Scroll upward and downward to check whether wheel events reach the browser in both directions.

Right-click is safely captured inside the live testing panel so the browser context menu does not interrupt the test.

How to Use the Mouse Test

1. Move your pointer around the large testing area.
2. Press the left, middle and right mouse buttons.
3. Scroll the wheel upward and downward.
4. Double-click inside the panel to test double-click recognition.
5. Check that every action appears in the live results.

Privacy and Mouse Input

This test reads mouse movement, click and wheel events inside the testing panel. It does not require an account or browser permission.

The results are displayed on the page so you can check whether your browser detects each mouse control correctly.

What the Online Mouse Test Checks

The interactive mouse tester separates pointer movement, button presses, double-clicks and wheel events into clear live results. This helps you identify missing, repeated or inconsistent mouse input without installing additional software.

Left mouse button

Press and release the primary mouse button and confirm that the on-screen left control highlights only while the button is held.

Right mouse button

Right-click safely inside the test panel. The browser menu is blocked in that area so the page can detect the button.

Middle mouse button

Press the scroll wheel as a button and check whether the browser reports a middle-button input.

Scroll wheel direction

Scroll upward and downward to confirm that wheel events reach the browser in both directions.

Pointer movement

Move around the panel and watch the pointer coordinates and total distance update to check continuous movement.

Double-click response

Double-click inside the testing area and review the counter to check whether the browser recognises the action.

Mouse Buttons, Movement and Wheel Results Explained

Each result describes an input received by the browser while your pointer is inside the testing panel. The readings provide a practical functional check rather than a laboratory measurement of sensor accuracy or click latency.

Pointer position

The X and Y coordinates show the current pointer position relative to the top-left corner of the movement panel.

Distance moved

This running total estimates how far the pointer has travelled inside the panel since the test was opened or reset.

Last button

The latest recognised button is shown as Left, Middle, Right, Back, Forward or a numbered additional button.

Total clicks

The click counter increases on each detected mouse-button press inside the testing area.

Double-clicks

The double-click counter increases when two presses are close enough together for the browser to recognise a double-click.

Scroll wheel

The wheel result shows the latest scroll direction and the size of the browser wheel event.

When to Use an Online Mouse Tester

A browser mouse test is a useful first step before changing settings, cleaning a mouse, replacing batteries, reinstalling drivers, returning a device or arranging a repair.

When a mouse button stops working

Press the suspected button repeatedly and compare it with the other controls to see whether any input reaches the browser.

When clicks repeat unexpectedly

Watch the click and double-click counters for extra activations that may indicate a worn switch or sensitive timing setting.

When scrolling feels inconsistent

Scroll in both directions and look for missed events, reversed direction, sudden jumps or repeated movement.

Before buying, selling or returning

Check movement, every available button, the wheel and double-click response and record any repeatable fault.

Browser and Mouse Compatibility

Standard left, middle and right buttons usually work in current desktop browsers. Additional side buttons, gesture controls, horizontal wheels and manufacturer-specific functions may be handled by the operating system or mouse software instead.

Touchpads can also generate mouse events, but taps, gestures and scrolling behaviour may differ from a physical USB or Bluetooth mouse.

What This Mouse Test Cannot Diagnose

The page can confirm browser input events but cannot inspect the optical sensor, switches, encoder, cable, battery, wireless receiver, firmware or internal electrical condition.

It also does not measure DPI, polling rate, click latency or sensor precision accurately. Those checks require dedicated software, controlled movement and specialist equipment.

Mouse Input Not Detected?

Try these checks before deciding that your mouse or one of its controls is faulty.

Use the testing panel

Move, click and scroll inside the large dashed panel so the page can capture and display the input.

Reconnect or recharge

Reconnect the USB cable or receiver, replace or charge batteries, or pair the Bluetooth mouse again.

Clean the controls

Dust around a button, wheel or sensor can contribute to missed clicks, repeated input or inconsistent movement.

Try another browser or device

Compare a current browser, another USB port or another computer to separate a mouse fault from a software or connection issue.

What the Mouse Test Results Mean

A working mouse button should highlight when it is pressed and return to its normal appearance when released. Pointer coordinates should change smoothly as you move around the panel.

The wheel result should change when you scroll. Missing, repeated or inconsistent inputs may indicate a hardware issue, dirt around a switch, a connection problem or an operating-system setting.

Frequently Asked Questions

Is this mouse test free?

Yes. The mouse tester is free to use and does not require an account or software installation.

Can I test the right mouse button?

Yes. Right-click inside the testing panel. The browser context menu is disabled only inside that panel so the click can be detected.

How do I test the middle mouse button?

Press the scroll wheel as a button. The middle-button result should change when the browser detects it.

Can this test detect a faulty scroll wheel?

The test shows whether upward and downward wheel events reach the browser. It cannot inspect the wheel mechanism physically.

Why does my mouse double-click unexpectedly?

Unexpected double-clicks can be caused by a worn switch, software settings or a double-click speed setting that is too sensitive.

How do I test mouse movement?

Move the pointer around the large testing panel. The coordinates and distance counter should update continuously without long gaps or unexpected jumps.

Can I test a wireless or Bluetooth mouse?

Yes. Connect the mouse normally, then run the same button, movement and wheel checks. Battery level, interference and receiver placement can affect wireless performance.

Can I test a laptop touchpad?

Yes. A touchpad can generate pointer, click and wheel events, although taps, gestures and multi-finger scrolling may behave differently from a physical mouse.

Can the test detect extra mouse buttons?

Back, forward and other buttons may be reported as additional button numbers. Manufacturer-specific controls may be intercepted by mouse software or the operating system.

Why does my scroll wheel move in the wrong direction?

The operating system may use natural or reversed scrolling. Check the device's scrolling settings before assuming the wheel hardware is faulty.

Why does the pointer jump or skip?

Pointer jumps may result from a dirty sensor, reflective surface, weak wireless connection, low battery, driver issue or failing sensor.

Can this mouse test measure DPI?

No. The movement distance is relative to the browser panel and is not a calibrated DPI measurement.

Can this test measure mouse polling rate?

No. Reliable polling-rate measurement requires precise event timing and dedicated testing software.

Does the mouse tester record or upload my input?

No. The page displays movement, button and wheel events locally in the browser while you use the testing panel.
