Double click test
Click the target once at a time. If the mouse sends two clicks for one press, the counter and the log show it.
Double click test workspace
How to use
4 short steps.
Click the target once at a time
Use single clicks at a normal pace. Left, right, and middle buttons all count, so test the button that is giving you trouble.
Watch the suspected double click counter
If two presses of the same button arrive less than 80 milliseconds apart, the counter goes up and the target flashes.
Repeat twenty or thirty times
A worn switch does not bounce on every press. Keep clicking and see whether the count keeps rising.
Adjust the threshold if you need to
The menu next to Reset sets the gap that counts as suspicious: 50, 80, or 120 milliseconds.
What the result means
Match what you see to one of these.
If the suspected count stays at zero, the switch is clean
If thirty single clicks produce no suspected double clicks, the button is sending one press per click and the problem is elsewhere.
If the count keeps rising, the switch is bouncing
If single clicks keep producing pairs under 80 milliseconds, the switch contact is worn. No person clicks that fast on purpose.
If only the browser double click count rises, that is normal
The browser counts any two clicks inside your system double click time, usually 500 milliseconds. That is a deliberate double click, not a fault.
Troubleshooting
If the test fails, try these in order.
Check the double click speed setting
On Windows open Settings, Bluetooth and devices, Mouse, Additional mouse settings, Buttons. On macOS open System Settings, Accessibility, Pointer Control. Move the slider, then click the target again.
Close remapping software and remote desktop
Macro tools, accessibility software, and remote sessions can duplicate clicks. Quit them, reload this page, and click again.
Blow out the switch
Dust and debris inside the switch cause bounce. Use compressed air around the button seam with the mouse unplugged, then retest.
Update firmware or enable debounce
Some mouse apps offer a firmware update or a debounce setting that filters bounces. Apply it and click the target again.
Replace the switch or the mouse
If the count still rises, the switch is worn. Use the warranty, have the switch replaced, or replace the mouse, then confirm here.
What this test can't tell you
Where a browser check stops.
- The browser only reports when each press arrives. A gap under 80 milliseconds is strong evidence of switch bounce, not proof of it.
- The browser dblclick event uses your operating system double click time, so it fires for deliberate double clicks and is shown only for reference.
FAQ
Common questions about this test.
What is a double click test?
A page where you click once at a time and it tells you whether the mouse sent two clicks. Bounce shows up as two presses a few milliseconds apart, far faster than a person can click twice.
How do I fix a mouse that double clicks?
Clean the switch with compressed air, update the mouse firmware, and turn on debounce in the mouse app if it has one. If the count on this page still rises, replace the switch or the mouse.
Why does my mouse double click when I click once?
The metal contact inside the switch is worn and bounces, so one press makes two signals. Dust, static, and a cheap switch make it worse. Warranty replacement is the usual fix.
Where is the double click speed setting?
Windows: Settings, Bluetooth and devices, Mouse, Additional mouse settings, Buttons tab. macOS: System Settings, Accessibility, Pointer Control, Double-click speed. A slower setting groups two clicks more easily.
