Waiting for more clicks

What this test measures

This test checks the gap between clicks of the same button. Click slowly and release the button fully each time.

Step-by-step instructions

How to Test Your Mouse for Double Clicking

To run the mouse double click test, press and release your mouse button slowly in the test area above. The checker looks at each button separately, so left and right clicks are not confused.

1

Choose a mouse button

Leave Auto selected to test whichever button you click first, or choose Left, Right, Middle or a side button. Test one button at a time.

2

Make 25 slow single clicks

Click in the test area and let go fully each time. Do not double-click on purpose. You need a mouse; touchscreen taps and pen input do not count.

3

Review results and retest

Look at the extra-click warning and the time between clicks. If you see a warning, try another browser, USB port or computer, then test again.

Understand the result

How to Tell If Your Mouse Is Double Clicking

If your mouse seems to click twice when you press once, check whether the test found two clicks unusually close together. A warning means you should try again. It does not necessarily mean your mouse is broken.

No extra clicks detected

No unusually close clicks were found this time. If the problem happens only occasionally, keep testing or try again later.

Possible extra clicks detected

The test found clicks that were unusually close together. Try another round of slow single clicks to see if it happens again.

Possible extra clicks in both rounds

Unusually close clicks appeared in both rounds. Try the same button in another browser or on another computer, and check your mouse settings.

Could not get a reliable result

The test could not measure some clicks clearly enough. Start again, and let go of the mouse button fully after every click.

What this test can and cannot tell you

The test checks the clicks your browser receives, not the parts inside your mouse. It cannot tell you exactly why a click happened twice. Even if no problem appears, your mouse could still have an occasional fault. Use a physical mouse rather than a finger or stylus.

Understanding click timing

What Do the Click Times Mean?

The test measures how much time passes between clicks of the same mouse button. Very short gaps are worth checking when you are trying to click slowly. These numbers are guides, not a diagnosis.

Time between clicksWhat to do
50 ms or lessA very short gap may mean an extra click. Click slowly and test again before deciding there is a problem.
51 – 100 msThis may be a quick double-click you made on purpose. Slow down and try again.
More than 100 msThe gap is not unusually short. If your mouse still clicks twice by itself, keep testing.

Troubleshoot unexpected clicks

Why Does My Mouse Double Click When I Click Once?

Your mouse might click twice because of its button, its settings, a wireless connection, or the app you are using. Start with the checks below. For more help, see how to fix unwanted double-clicking.

Mouse settings and software

Check whether mouse software, custom button settings or a single-click-to-open setting is causing the unwanted action.

Connection and power

If you use a wireless mouse, check the battery and USB receiver. Try another USB port or computer to see if the problem continues.

Worn button or app problem

A mouse button can wear out over time, but some apps also handle clicks differently. Try another browser or computer before replacing your mouse.

Double Click Test: Common Questions

How do I test if my mouse is double clicking?

Choose Auto or select a mouse button in the test above. Click slowly 25 times, letting go fully after each click. If the test finds possible extra clicks, try again to see if they happen more than once.

Why does my mouse double click when I click once?

A worn mouse button, mouse settings, a connection problem or a particular app could be responsible. Try another browser or computer before assuming the mouse is broken. See our troubleshooting guide.

How can I fix a mouse that double clicks?

Check your mouse settings and any custom button controls. If you use a wireless mouse, check its battery and USB receiver. Try another browser or computer. If the problem continues, contact the mouse manufacturer or check your warranty. See the full guide.

Does a very short gap between clicks mean my mouse is broken?

No. While you are clicking slowly, a gap of 50 ms or less may be an unwanted extra click. A gap from 51 to 100 ms is harder to judge. These times are guides, not proof of a broken mouse. You can read how the test works.

Is a double click test the same as a double click speed test?

No. This test looks for extra clicks you did not intend. A double click speed test measures how quickly you can click twice on purpose. To check whether buttons work, use the mouse button test.

Can I test wireless mice or side buttons?

Yes. Wireless and Bluetooth mice work as long as the browser can receive their clicks. You can also try Back and Forward buttons, although some browsers may handle them differently. Test one button at a time.

Why are touchscreen taps not counted?

A touchscreen tap or stylus press cannot tell you whether a physical mouse button is double-clicking. Connect a USB or Bluetooth mouse and click inside the test area instead.

Are my mouse clicks uploaded or saved?

Your individual clicks and click history stay on this page and disappear when you refresh or leave. We do not upload your click history. We may collect basic site usage statistics, but not the clicks you make during the test. See our privacy policy.
