Double Click Test — Test Your Mouse and Double-Click Speed
Two tools in one: measure your double-click interval in milliseconds, and use the click counter to detect a faulty mouse that fires double-clicks on its own.
Speed mode
Double-click here as fast as you can — interval between the two clicks
Mouse fault checker
Click ONCE, slowly. If the counter jumps by 2, your mouse is double-clicking by itself.
Two intents, one page
Speed mode measures the gap between your two clicks — most deliberate double-clicks land between 100 and 300 ms, and operating systems accept anything under roughly 500 ms as a double-click. The fault checker answers a different question: is your mouse double-clicking when you only clicked once? Click slowly and watch the counter — jumps of 2 from a single press mean the switch is bouncing.
If your mouse fails the check
Switch bounce comes from worn or dirty contacts inside the micro-switch. Before replacing the mouse: raise the debounce time in your mouse software if it has one, try a different USB port (rules out software), and blow out dust around the button. If bouncing persists, the switch — or the mouse — needs replacing. Related tools:CPS test,spacebar speed test andmouse accuracy test.
Frequently asked questions
What is a double click test?
A double click test measures the time between two consecutive clicks in milliseconds. It has two uses: benchmarking how fast you can double-click, and diagnosing a faulty mouse that registers unintended double-clicks.
What is the normal double click speed?
Operating systems typically treat two clicks within about 500 ms as a double-click. Deliberate human double-clicks usually land between 100 and 300 ms apart; intervals under ~80 ms that you didn’t intend are a red flag for a worn mouse switch.
How can I test if my mouse is double-clicking by itself?
Use the counter panel on this page: click slowly and deliberately, once at a time. If single clicks register as 2 or more, your mouse switch is bouncing — a classic hardware fault.
What causes unintentional double-clicking on a mouse?
A worn or dirty micro-switch whose metal contacts "bounce" on release. It’s common on heavily used mice; fixes range from adjusting debounce time in mouse software to replacing the switch or the mouse.
Can this test work with a keyboard’s Enter or spacebar key too?
Yes — focus the test area and double-press Enter or Space; the interval between presses is measured the same way. For pure key-pressing speed, the spacebar speed test is the better tool.
How this test works: everything runs and is timed locally in your browser, and results depend on your device and conditions. Scores are for casual benchmarking and entertainment — not a clinical, medical or diagnostic measurement.
