Test Your Mouse Double-Click Speed
Click twice in the test area to measure the exact interval between clicks, see whether it registers as a double-click and catch early signs of a failing mouse button.
What This Double-Click Test Measures
Precise, millisecond-level click timing without any installation
Click Interval
Every click is timed in milliseconds so you can see the exact gap between two clicks
Double-Click Detection
Intervals below your chosen threshold are labelled as double or triple clicks
Chatter Detection
Intervals under 40 ms flag a possible switch bounce, a common sign of a worn button
Visual Chart
A bar chart of recent intervals makes slow clicks and chatter spikes easy to spot
Custom Threshold
Adjust the double-click window from 150 to 900 ms to match your system settings
100% Local
All timing happens in your browser. No data is uploaded or stored anywhere
How to Test Double-Click Speed
Four simple steps to measure and evaluate your mouse clicks
Adjust the threshold
Set the double-click window to match your operating system, usually 500 ms
Click in the test area
Double-click inside the dotted area at your normal speed - the interval is recorded instantly
Read the result
Check the last interval, the speed rating and whether it registered as a double-click
Repeat a few times
Repeat several double-clicks to see whether intervals are consistent or erratic

Frequently Asked Questions
Common questions about double-click and mouse button testing
What is a normal double-click speed?
Most people double-click with an interval between 100 and 300 milliseconds. Default operating system thresholds are around 500 ms, so anything under that counts as a double-click.
Why do I see chatter or bounce events?
Chatter means the mouse button generated two contact closures only a few milliseconds apart. This usually indicates a worn or dirty switch and often explains accidental double-clicks while dragging.
Does this test change my system double-click settings?
No. The threshold here only affects how clicks are labelled on this page. Your operating system setting stays untouched.
Can I test the right mouse button?
This test focuses on the primary button, which is the one used for double-clicking. Right and middle buttons are covered by the mouse button test page.
Why do click intervals sometimes look random?
Human timing varies, and operating systems may throttle event delivery. Compare several attempts and look at the average rather than a single measurement.
Does the test work with a touchpad or touch screen?
Yes. A trackpad double-tap or a touch double-tap generates the same events, so the interval measurement works the same way.
