Keep scrolling in one direction inside the test area. Reverse events are counted because they can point to wheel bounce, touchpad inertia, or inconsistent hand movement.

Mouse tester guide

How to run an accurate online mouse test

Use this online mouse tester to check left click, right click, middle click, scroll wheel input, and basic pointer response before you blame a game, browser, USB port, or wireless connection.

If you want the underlying technology explained first, read how ball, optical, and laser computer mice turn movement into cursor data, then come back here to test the buttons and wheel on your own device.

This page checks whether each button works. If you want to measure how fast you can click, run the mouse click test instead — it counts your clicks per second (CPS) over timed rounds.

If you are choosing a compact Bluetooth mouse for travel, compare the practical tradeoffs in the Dell MS700 vs portable Bluetooth mice guide, then run this page after pairing to confirm buttons and scroll behavior.

01 Test every main mouse button Click inside the test area and press left, right, and middle click once. A healthy switch registers one clean press and returns to released.

02 Check the scroll wheel direction Scroll up and down over the panel. The wheel counter and direction status should update smoothly without jumps, skips, or reverse movement.

03 Repeat suspicious clicks slowly If one press logs twice or stays active too long, compare it with the focused double click test and retest after cleaning the switch area.

04 Move to deeper mouse diagnostics After the button test, use the mouse DPI tester, input latency test, mouse trail test, and mouse accuracy test to check sensitivity, delay, pointer path, and aim control. If the same DPI feels different after a mouse swap, use the same-DPI sensitivity guide.

Mouse test FAQ

Common online mouse tester questions

How do I test my mouse buttons online?

Click inside the mouse tester and press the left, middle, and right buttons. Each button should update the correct counter and status immediately.

How do I test my scroll wheel?

Move the scroll wheel up and down while the pointer is over the test panel. The scroll count and latest direction should change with each wheel movement.

Can this mouse tester detect double click problems?

It can reveal suspicious extra presses, but use the dedicated double click test when you need click interval logging for switch bounce.

Does the mouse test work with wireless and Bluetooth mice?

Yes. Wired, wireless, Bluetooth, and many trackpads work as long as the browser receives standard mouse events from the device.

Can I test DPI, polling rate, or pointer accuracy here?

This page checks buttons, wheel, and basic pointer input. For deeper measurements, use the mouse DPI test, polling rate test, or mouse accuracy test.

Is mouse test data uploaded?

No. The test runs in your browser and the button or scroll input is handled locally on the page.
