Double Click Test

~30 sec

  1. Click the box 20 times at a normal pace, with any mouse button.
  2. Leave a moment between clicks, and don't double-click on purpose.
  3. Each time one press arrives as two, it is counted as a double click.

The back and forward buttons count too; they won't leave the page.

Your result: — double clicks

How does the double click test work?

Click the box 20 times at a normal pace, with any button: left, right, middle, or the back and forward buttons on the side. Each press is listed under its button as it arrives. If one press arrives as two, the box says so at once, and the result counts how often it happened. The back and forward buttons are held back over the box, so they won't leave the page.

How does it spot a double click?

A press of a button less than 80 ms after the previous press of the same button is counted as a double click. If you leave at least 250 ms between clicks, as the page asks, none of your own presses come close to that, so a press that soon is one your finger didn't make: the mouse sent a single press twice. Presses of two different buttons close together are two clicks, not a double click.

Why does a mouse double-click by itself?

Usually because of a worn switch. Under each button is a small switch whose metal contact bounces as it closes, opening and closing more than once in a single press. The mouse ignores its button for a few milliseconds after each click so the bounces don't count, which is called debouncing. As the switch wears, it can bounce for longer than that pause, and the extra bounce reaches the computer as a second click. Dust or damp inside the switch can do the same.

What can you do about a mouse that double-clicks?

  1. Try the mouse in another USB port, or with fresh batteries if it is wireless, and test again.
  2. If the mouse has its own software, look for a debounce setting and raise it a little.
  3. If the double clicks come from one button only, the switch under it is worn: it can be replaced, or the mouse.

The double-click speed in your computer's settings doesn't cause this. It only decides how close together two real clicks must be to open a file; it never adds clicks.

What can't a double click test see?

It sees what your browser receives, after the mouse and the computer have done their work. A bounce the mouse filters out never reaches it, and neither does a press the mouse swallows. For clicking speed rather than faults, try the CPS Test or the Right-Click CPS Test.

Questions

What does a double click test check?
Whether your mouse sends one press as two. A second press of the same button less than 80 ms after the first is counted, because a finger clicking at a normal pace doesn't press that fast.
I got one double click. Is my mouse broken?
Not necessarily: a press can slip into a quick double by accident. Run the test again, slowly. If double clicks keep appearing on the same button, the switch under it is likely worn.
Does the double-click speed setting matter?
No. That setting decides how close two real clicks must be to count as a double click when opening files. It doesn't make the mouse send extra presses, and this test doesn't use it.
Why are the back and forward buttons included?
Their switches wear like any other. The page stops them from leaving the page while your pointer is over the box, so you can test them too.
Can I test a touchscreen or a touchpad?
Taps are counted, but a screen has no switch that wears like a mouse button's. A touchpad with physical buttons can be tested like a mouse.
