Mouse Test
Click, scroll and move your mouse inside the test area below. Every button, wheel step and double-click glitch is shown live.
How to read the result
Press each button once: its box must light up. If a button does not register, or the same press registers twice, the switch is worn. A gap under about 50 ms between two clicks of one physical click is almost always a double-click fault (switch chatter), not a fast finger. Scroll slowly in both directions: every notch should count once and in the right direction. The polling rate is estimated from how often the browser receives pointer movement while you move quickly; 125 Hz is a basic mouse, 500 Hz a good one and 1000 Hz or more a gaming mouse.
Questions
How do I test if my mouse buttons work?
Click inside the test area with each button. The matching box lights up and counts every click. If a button does not light up, it is not sending a signal and the switch or cable may be faulty.
What is a double-click problem?
Over time a mouse switch can bounce and register two clicks for one press, which opens files unintentionally or breaks drag and drop. This test flags two clicks of the same button that are only a few milliseconds apart. A human cannot click twice within 50 ms.
How is the polling rate measured?
The page measures the time between the pointer events the browser receives while you move the mouse fast. Typical results are about 125, 250, 500 or 1000 Hz. Browsers and the display refresh rate can lower the reading, so treat it as an estimate and compare mice on the same computer.
Why does the right-click menu not open here?
Inside the test area the context menu is turned off so that the right button can be tested. Outside the box it works as usual.
Is my mouse data stored?
No. Everything runs in your browser and nothing is stored or uploaded.
