Double Click Test
Detect fast repeated clicks and inspect the interval history between clicks.
How to use this test
Click the large surface normally, then try repeated single clicks. Compare the custom fast-pair counter with the browser-native dblclick counter and watch the interval history.
How the measurement works
Every click receives a high-resolution timestamp. Pairs within 300 ms are shown as fast pairs, while the browser's own dblclick event is counted separately so you can compare custom timing with native behavior.
How to interpret results
Unexpected fast pairs or native double-click events during normal single clicking can indicate switch bounce, worn hardware or aggressive debounce settings. One isolated event is less meaningful than repeated behavior.
Troubleshooting tips
Try slower deliberate clicks, a different USB port and another browser. If unwanted doubles repeat across apps and browsers, check vendor debounce settings or test a different mouse.

Common double click questions
Why does my mouse double-click when I click once?
Repeated double clicks from deliberate single presses can come from switch bounce, a worn microswitch, very aggressive debounce settings or remapping software. Test several slow single clicks and compare the behavior in another browser or computer.
Read full answer →What is mouse debounce and how does it affect double clicks?
Debounce is the delay or filtering used to ignore electrical bounce from a physical switch. Very low debounce can expose extra clicks, while higher debounce can reduce accidental doubles at the cost of a small amount of click latency.

A worn switch often produces intermittent missed presses or unintended fast pairs during normal single clicking. Consistent failures across browsers, USB ports and systems are stronger evidence than one isolated double click.

A fast pair is our 300 ms timing check. A native double click is the browser's dblclick event, which also reflects platform/browser double-click behavior.
