Free Mouse Test
Test your mouse buttons, scroll wheel and double-click speed, spot a chattering switch, and measure clicks per second in a 5-second test.
Click, double-click and scroll inside the box. Every button press is counted, double-click timing is measured, and a fast double-registered click is flagged.
Back and Forward are the side buttons found on some mice. They only count if the mouse and its driver pass them to the browser. The right-click menu is switched off inside the test box only.
Double-click
Two presses of the same button within 500 ms count as a double-click, and the gap between them is measured.
Click chatter detector
No chatter detected. A press is flagged when the same button registers twice less than 80 ms apart.
Scroll wheel
Counts wheel events over the test box. The page does not scroll while the pointer is inside it. Smooth wheels and trackpads send many small events per turn.
Clicks per second
Press "Start 5-second test", then click the box with the left button as fast as you can.
🖱️ Clicks and scrolls are read inside this tab only and are never recorded or uploaded.

How It Works
The page reads mouse events inside the test box and turns them into counts and timings.
- 1Press every buttonClick inside the box with the left, middle and right buttons, and the side buttons if your mouse has them. Each button lights up while held and keeps its count.
- 2Check double-clicksDouble-click and read the measured gap between the two presses. If one click registers twice less than 80 ms apart, a chatter warning appears.
- 3Spin the wheelScroll up and down over the box to count wheel events in each direction without moving the page.
- 4Run the 5-second testPress "Start 5-second test", then click as fast as you can. The first left click starts the timer, and the result is clicks per second.
Mouse events are read in your browser tab only. Nothing is recorded, stored or uploaded.
