Free Double Click Test for Mouse Timing, Bounce, and Unwanted Double Clicks
This double click test records raw pointer presses, inter-click timing, browser dblclick events, and suspicious ultra-fast repeats that can help identify unwanted double-click behavior.

How to read the diagnostic signal
| Signal | Useful interpretation | Important limitation |
|---|---|---|
| Stable repeat result | More useful for comparison than a single isolated sample | Still depends on the current browser, OS, and device state |
| Large change after one controlled adjustment | Good clue that the changed variable matters | Correlation is not always proof of root cause |
| Missing or inconsistent browser event | Useful troubleshooting evidence | Does not electrically inspect hardware components |
| Exported session summary | Helps compare before/after changes | Only as good as the test conditions you record |
Worked example: run the same test twice, change one relevant setting, then repeat it. A consistent change across repeated runs is more informative than a single isolated number.
Six short lessons for better testing
Control one variable
Keep device settings, browser zoom, and test mode constant before comparing results.
Repeat the measurement
One run can be noisy. Repeat the same test and look for a stable pattern.
Separate browser from hardware
Browser events are useful diagnostics, but they do not expose every firmware or electrical detail.
Use the right metric
Choose timing, accuracy, count, support, or geometry metrics that match the problem you are investigating.
Record context
Save the device, connection type, relevant settings, and test condition with any result you compare later.
Interpret, do not overclaim
Treat the page as a practical diagnostic aid rather than a laboratory certification instrument.

Free Double Click Test for Mouse Timing, Bounce, and Unwanted Double Clicks: FAQ
What counts as a double click here?+
Two presses on the selected mouse button are grouped when their interval is at or below the threshold you choose.
What is an unwanted double click?+
A switch can sometimes register two electrical activations from one intended press. Very short repeated intervals can be a clue, but this browser tool cannot prove hardware bounce by itself.
Why does browser dblclick differ from the custom pair count?+
The browser and operating system apply their own double-click interpretation, while the custom pair count uses the threshold selected on this page.
Can I test the middle or right button?+
Yes. Change the button filter and use the test pad. Context-menu behavior is suppressed inside the pad for easier right-button testing.
Does this test mouse debounce firmware?+
It observes browser-visible events only. Firmware and hardware debounce behavior are inferred from event timing, not measured electrically.
Use the result responsibly
This tool reports what a browser can observe or calculate in the current environment. Firmware, drivers, operating-system processing, permissions, transport, display timing, audio hardware, device design, and browser implementation can add behavior that this page cannot isolate.
