Double Click Test
Check whether one slow mouse press appears as a rapid repeat in your browser. Test individual buttons, review millisecond gaps, and measure your intentional double-click timing without installing software.

ONE PRESS SHOULD LOOK LIKE ONE PRESS
Separate suspicious repeats from an intentional double-click.
Use the guided mode for slow single clicks. A separate timing mode measures deliberate double-click pairs, so the two different tasks do not get mixed together.
DIRECT ANSWER
How do I test if my mouse is double clicking?
Choose the button that feels unreliable, start the test, then make 20 slow single clicks with roughly half a second between each press. A repeat received in under 80 milliseconds is highlighted for a second test. Repeat the check in another browser, USB port or computer before deciding the physical switch is faulty.
A REPEATABLE CHECK
Run a useful mouse double-click check
Consistent spacing makes unintended repeats easier to separate from your own fast clicking.
Make slow single clicks
Use ordinary pressure and wait about half a second between each of the 20 presses.
Read the timing, not only the count
Very short repeats are highlighted; 80–250 ms gaps remain ambiguous because a person can click that quickly.
Retest before acting
Compare another browser, port or mouse. Check operating-system settings if only normal double-clicking feels wrong.
READ THE SIGNAL
What the browser result means
The page reports the events it receives. Treat the pattern as a clue, not a physical inspection of the switch.
The browser did not receive an unusually fast repeat during 20 slow clicks.
Your own rhythm may have been quick enough to look like a double-click.
Retest on another setup; repeated signals this fast can be consistent with switch bounce.
Compare the same button elsewhere and review that app or the operating-system double-click setting.
PRACTICAL USE
Useful when checking a new or used mouse
Run the same 20-click sample for each button before buying, after changing batteries or ports, and when a mouse begins opening files twice. In Bangladesh, this can also create a simple repeatable note before contacting the seller or using the applicable warranty process.
HONEST LIMIT
A browser test cannot inspect the hardware
This tool can record click timing and browser double-click events. It cannot see the switch contacts, debounce firmware, USB receiver, battery, driver or internal damage. A single highlighted gap is not proof of failure. Retest under the same conditions and follow the manufacturer's safe cleaning, support or warranty guidance; do not open a mouse that is still under warranty.

COMMON QUESTIONS
Double click test: common questions
Direct answers about mouse double clicking, timing, button choice, repeat counts, browser limits and safe next steps.
How can I test if my mouse is double clicking?
Select the affected button, start the guided check and make 20 slow single clicks. Watch for repeat events that arrive far sooner than your deliberate half-second spacing.
What result suggests an accidental double-click issue?
A repeat under 80 ms during deliberately slow single clicks is worth retesting. The same pattern across browsers, ports or computers is more meaningful than one isolated event.
Why does my mouse double click when I click once?
Possible causes include switch wear or contamination, low wireless power, connection problems, mouse software, an app setting or the operating-system double-click configuration. A browser test cannot identify the cause by itself.
How many clicks should I use for a double click test?
Twenty slow presses is a practical first sample. If the issue is intermittent, repeat the set several times while keeping your timing and pressure consistent.
Can I test the right and middle mouse buttons?
Yes. Choose the button before starting. Right-click menus are suppressed inside the test pad, while side-button detection can still vary by mouse software and browser.
What is the difference between a double click test and a CPS test?
A double-click diagnostic looks for unexpected repeated signals during slow clicks. A CPS test measures how many intentional clicks you can make per second; a high score does not prove switch health.
Can this test prove that my mouse switch is broken?
No. It only shows events and timing received by the browser. Confirm a repeated pattern on another setup and follow the manufacturer's troubleshooting or warranty process.
How do I change double-click speed in Windows?
Open Windows mouse settings, choose Additional mouse settings, then use the Double-click speed control on the Buttons tab. This changes how Windows interprets intentional double-clicks; it does not repair a worn switch.
