Double Click Test
Free · No installYou make one click. Does the browser receive another? Test with spaced single clicks.
A mouse needs a computer.
Open this page on a computer and connect your mouse to test it. You can copy the link below.
A connected mouse on a touchscreen device can also work. Touch taps cannot test physical mouse buttons.
Make 20+ single clicks on your selected button. Pause about ½ second between clicks; do not deliberately double-click.
Back/Forward mouse events and delivered navigation shortcuts are blocked while a test is active. The diagram uses a default layout: front side = Forward (F), rear side = Back (B), as on a default Logitech G102. A driver command that never reaches this page may still navigate; use standard side-button assignments in your mouse software for this test.
Your result
Browser observations only. Compare another port or computer before concluding there is a hardware fault.
How to read your result
Select one mouse button, start the test and make at least twenty single clicks. Pause about half a second between each press. The tool flags two same-button presses separated by less than the selected interval when a release occurred between them. The default 150 ms is an investigation threshold for this paced protocol, not a specification for every mouse. Changing it changes which intervals are flagged. The operating system’s double-click setting answers a different question: whether two clicks activate an application’s double-click action. This test does not use that action as proof of a fault. If you deliberately click quickly, you can produce the same pattern as an unwanted repeat. Excellent means twenty complete cycles without a flagged signal. A Suspected issue result asks for a careful retest and another port or computer. The response score measures this sample and cannot separate switch bounce, remapping software and user technique.
What to do if something looks wrong
- Reconnect the mouse or receiver directly to a different USB port. Bypass an unpowered hub.
- Check charge, batteries and visible cable damage. Replace a detachable cable with a compatible known-good cable.
- Disconnect the mouse before gently clearing loose dust around buttons and the wheel. Follow the maker’s cleaning instructions; do not pour liquid into it.
- Check button assignments and install updates from your operating system or mouse manufacturer. Avoid third-party driver download sites.
- Repeat on another computer. A symptom that follows the mouse makes a hardware problem more plausible, but browser results alone cannot identify a worn switch or encoder.

Frequently asked questions
How do I test for unwanted double clicks?
Make deliberate single clicks with a pause of about half a second. A short second press after a complete click is a signal to investigate. Reproduce the symptom across applications and another computer before identifying a hardware cause.
What is the interval threshold?
It is the maximum down-to-down gap flagged by this tool. The default is 150 ms and the selectable range is 80 to 250 ms. There is no universal threshold that diagnoses a faulty mouse switch from browser events.
Why does intentional fast clicking produce a warning?
The browser receives timing, not your intention. Rapid intentional clicks and unwanted repeat clicks can have the same event pattern. Follow the paced single-click instructions for a useful comparison.
Will changing Windows double-click speed repair a worn switch?
That setting changes how applications group clicks. It does not establish whether a physical switch is worn. Check mappings, connection and drivers, then compare the mouse on another computer.
