Example
Example: finding a chattering left button
An older mouse sometimes opens files on a single click. In the test area, click the left button slowly, about once a second, twenty times, with the double-click threshold at its default of 80 ms.
- Each press is compared with that button’s last release.
- A press 120 ms after the release is an ordinary click and adds only to Clicks.
- A press 35 ms after the release is too soon for a finger: it also adds 1 to Double clicks.
| Gap after release | Threshold 50 ms | Threshold 80 ms |
|---|---|---|
| 35 ms | Double click | Double click |
| 60 ms | Ordinary click | Double click |
| 120 ms | Ordinary click | Ordinary click |
If Double clicks goes up while you click slowly, that switch is chattering. A healthy button stays at 0 with slow clicks at 80 ms.
How it works
- Click in the test area with every button — left, right, middle and the two side buttons — and turn the wheel both ways.
- Click slowly, one click at a time: if a Double clicks count goes up, that switch is chattering.
- Move the mouse fast in circles in the lower area to measure its polling rate in Hz.
Frequently asked questions
- Why does my mouse double-click by itself?
- The switch under the button is wearing out and bounces, sending two clicks for one press — called chattering. It is common in older mice; the fix is a new switch or a new mouse.
- What is a good polling rate?
- Office mice report 125 times a second; gaming mice 500 or 1000 Hz, some up to 8000. Higher feels smoother, if the software and screen keep up.
- Why does my measured Hz vary?
- The rate shows only while the mouse moves fast; slow movement sends fewer reports. The maximum is the best guide.
- Why do the side buttons go back a page?
- The test stops that where the browser allows it; some browsers or mouse software still navigate — click them inside the area.
- Which double-click threshold should I pick?
- 80 ms suits most tests. 50 ms flags only the fastest bounces; 100 or 150 ms also catches slower ones, but then quick double clicks you make on purpose count too, so click slowly.
- Can it measure my mouse’s DPI?
- Not on this page. The mouse DPI test does that: you move the mouse a measured distance along a ruler or a bank card, and it counts the reports.
- Is anything sent anywhere?
- No. The test runs in your browser; nothing is recorded or uploaded.
