What it detects
For each of the five buttons: total presses, suspected double-clicks under your threshold, the double rate and the shortest gap between two presses. The timeline shows the last 20 clicks with doubles in red.
Mouse Button Fault Check
Mouse Double Click Test
Find out whether your mouse is double-clicking on its own. Click each button slowly and the test flags any second press that arrives too soon to be yours, on all five buttons.

Double-click threshold
Two presses of the same button closer together than this are flagged as a suspected double-click.
Press Start, or just click here
Make slow, deliberate single clicks, about one per second. The right-click menu, middle-click scrolling and back/forward navigation are blocked inside this box.
Start the test and click each button slowly to check it.

About the Mouse Double Click Test
• The test listens to every mouse button press inside the box and measures the time since the previous press of the same button.
• A worn or dirty switch can bounce and send two presses for one click. Those extra presses usually arrive within a few dozen milliseconds, faster than a person can click on purpose.
• Click slowly while you test. When you only make single clicks, any flagged double is a hardware or software fault, not your finger.
• Side buttons (back and forward) are included, because they fail too and are easy to overlook until a browser page jumps back by itself.
• The right-click menu and back/forward navigation are blocked only inside the test box, so the test never throws you off the page.
• Use the Right Click Test to measure right-button speed; this page is for finding faults on every button.
How to read your double click test results
A double-click fault is a timing problem: one physical click reaches the computer as two presses. These notes explain what the numbers mean and what to try next.
Test with the mouse connected the way you normally use it (cable, 2.4 GHz receiver or Bluetooth), and close macro software you do not need while testing.
Why mice start double-clicking
The usual cause is a worn micro-switch whose contacts oxidize and bounce. Static build-up, dirt, a low debounce setting in the mouse software and drivers or remapping tools that inject clicks can cause the same symptom.
How to fix it
Clean around the button, discharge static by unplugging it or removing the battery and pressing every button, raise the debounce time if your software offers it, or replace the switch. Under warranty, send the results to the manufacturer.
How to judge the result
While clicking slowly, even one flagged double in a few hundred clicks is worth watching; several per hundred means the switch is failing. Gaps under about 30 ms are almost never human. Retest after any fix to confirm.
Mobile and trackpad limits
Touchscreens and trackpads have no physical switch to wear out, and taps only simulate left clicks. Connect a mouse to a computer for a real check of the hardware.
Mouse Double Click Test FAQ
How to tell whether your mouse is really double-clicking, and what to do about it
How do I know if my mouse is double-clicking?
Start the test and click one button slowly, about once per second, for a minute. If the table shows suspected doubles while you were only making single clicks, the mouse is sending two presses for one click. Repeat with each button.
What threshold should I use?
80 ms is a good default. Switch bounce usually produces gaps well under 30 ms, while a deliberate fast double-click is rarely below 80 ms. Lower it to 50 ms if you click very fast, or raise it to 100–150 ms to catch borderline faults while clicking slowly.
Can a software setting cause double-clicks?
Yes. A very short debounce time in the mouse software, a macro or button remap, or a utility that injects clicks can all produce doubles. Try the mouse on another computer or with its software closed: if the doubles disappear, the cause is software.
Can a double-clicking mouse be fixed?
Often. Cleaning, discharging static (unplug the mouse or remove the battery, then press every button a few times) or raising the debounce time can help. A worn micro-switch is fixed for good by replacing it, and a mouse still under warranty should go back to the manufacturer.
What is the difference between this and the Right Click Test?
The Right Click Test measures how fast you can click the right button in a timed run. This page is a fault check: it watches all five buttons at a normal pace and flags presses that come too close together.
