Double Click Test: Is Your Mouse Double Clicking?
How to use it: press START TEST, then click the area slowly, one press at a time. If the Double Clicks box goes up while you are only single clicking, your mouse is sending two clicks for one press.
This double click test shows whether your mouse sends two clicks when you press a button once. Press START TEST, then click slowly inside the box. Every press adds to Single Clicks, and any press that arrives within 100 milliseconds of the one before it is counted as a Double Click. If that number rises while you click slowly, your mouse is double clicking on its own.
This mouse double click test is free and runs in your browser. There is nothing to install, no sign-up and no timer, and your clicks are not saved or sent anywhere.
How to use the double click test
A slow, steady double clicking test is the most reliable way to catch a faulty button:
- Press START TEST. The button disappears, and that first press already counts as one click.
- Click inside the box at a relaxed pace, about once a second. Press and release fully each time, the way you would click a link.
- Keep going for 50 to 100 presses. A worn switch often misbehaves only now and then, so a handful of clicks can miss it.
- Watch the Double Clicks box. With a healthy mouse it stays at 0 during slow clicking.
- Test the right button the same way. Left, right and middle presses all count, and the right-click menu is blocked inside the box.
- Press Reset to set all three boxes back to 0 and bring back the START TEST button.
If you want to check a specific button, use only that button for a full round, then reset before testing the next one.
How the double click tester counts clicks
The double click checker listens for every mouse button press inside the test area and compares its time with the press before it. The rule is simple: two presses 100 ms (0.1 seconds) or less apart count as a double click. Here is what each box means:
| Box | What it counts |
|---|---|
| Single Clicks | Every press the browser received, including both halves of a double click |
| Double Clicks | Presses that came 100 ms or less after the previous press |
| Total Clicks | Single Clicks plus Double Clicks |
An example makes the numbers easier to read. Say you press the left button 10 times, slowly, and the switch chatters on two of those presses. The browser receives 12 presses, so Single Clicks shows 12, Double Clicks shows 2 and Total Clicks shows 14. Those 2 extra presses are the ones you did not make.
The 100 ms window is deliberately tight. Windows treats two clicks as a double click if they come within 500 ms by default, according to Microsoft’s documentation. This test is stricter because it is looking for faults, not for normal double clicks you make on purpose.
Reading your result: is my mouse double clicking?
A healthy mouse shows 0 Double Clicks when you click slowly. Anything else needs a closer look:
| What you see during slow clicking | What it most likely means |
|---|---|
| Double Clicks stays at 0 after 100 presses | The button is working normally |
| 1 or 2 doubles in 100 presses | An early sign of a worn switch; test again later |
| Doubles every few presses | The switch is chattering; the fixes below may help, but replacement is likely |
| Doubles on one button only | The problem is in that button’s switch, not your settings |
| Single Clicks rises with no press at all | Look for a stuck button, a macro or software sending clicks |
Fast clicking gives a different picture in a double click mouse test. If you click as quickly as you can, some of your own presses will land inside 100 ms and count as doubles, even on a perfect mouse. That is why the slow method above is the real check, and fast clicking belongs on the CPS test instead.
Why a mouse double clicks on a single click
If your mouse is double clicking on one click, the cause is usually one of these:
- A worn switch. Each button sits on a small mechanical switch. Its metal contacts do not close cleanly; for a moment they bounce, opening and closing several times, as the QMK debounce documentation explains. The mouse firmware filters this out, but as the contacts wear or get dirty the bounce can outlast the filter, and one press reaches the computer as two.
- A Windows setting. If a mouse has double clicked since the first day, Logitech points to the Windows option “Single-click to open an item”, which makes one click open files as if you had double clicked (Logitech support). This changes how Windows reacts, not what the mouse sends, so this test will show normal single clicks.
- Double-click speed set very slow. With a long double-click time, two separate clicks you meant as single clicks can be read as one double click.
- Connection or power problems. A low battery, a weak wireless signal or a loose USB connection can make a mouse behave oddly.
- Software. Mouse utilities, macros and button remapping tools can add clicks you did not make.
A mouse that double clicks only now and then is the classic sign of the first cause. Switch wear tends to start as an occasional extra click and gets more frequent over time.
How to fix mouse double clicking
Work through the free software checks first, then the hardware:
- Run this mouse double clicking test on slow clicks and note how often Double Clicks rises, so you can tell if a change helped.
- Check the Windows single-click option. Open File Explorer Options, then the General tab, and under “Click items as follows” choose “Double-click to open an item”.
- Reset the double-click speed to the middle of the slider (see the next section).
- Change the connection. Plug the mouse or its receiver straight into a USB port on the computer, not a hub, and fit fresh batteries in a wireless mouse.
- Update or remove mouse software. Update the maker’s app and drivers, or remove them for a test and let the system use its built-in driver. Turn off any macros on the faulty button.
- Try another computer. If the extra clicks follow the mouse, the fault is in the mouse.
- Clean around the button. Unplug the mouse and blow out dust from the gap around the button.
- Use the warranty or replace the mouse. A chattering switch is a hardware fault. If the mouse is still under warranty, contact the maker. Replacing a switch needs soldering, so most people replace the mouse.
Some gaming mice let you raise the switch “debounce time” in their software. A longer debounce can hide mild chatter at the cost of a tiny delay, but it does not repair the switch.
How to change the double-click speed
A double click in mouse terms is two presses of the same button in quick succession, which opens a file or selects a word. Double-click speed is the longest gap your computer accepts between two clicks for them to count as a double click. A slower setting gives you more time; a faster one needs quicker clicks.
- Windows 11: Settings > Bluetooth & devices > Mouse > Additional mouse settings. On the Buttons tab, move the Double-click speed slider, then double-click the test folder next to it to try the new setting.
- Windows 10: Settings > Devices > Mouse > Additional mouse options, then the same Buttons tab.
- Mac: System Settings > Accessibility > Pointer Control, then drag the Double-click speed slider (Apple support).
The Windows default is 500 ms, and the longest value it allows is 5000 ms. Does double click speed affect gaming? Rarely, because games read each button press directly, so there is no best double click speed for gaming. It affects opening files and selecting words on the desktop, not your clicks per second.
Double clicking for CPS and gaming
Some players look for a mouse double clicker, or a “double clicker test” to find one, meaning a mouse whose switch registers extra clicks, to raise their clicks per second. A quick double click check shows whether a mouse does that: click slowly, and every Double Click is an extra input the mouse made by itself.
Keep two things in mind. A chattering switch is a failing switch, so it can get worse and start misfiring in normal use. And many game servers have rules about click speed and click aids, so check the rules of the server you play on before relying on it. If you want more clicks the honest way, compare jitter, butterfly and drag clicking or read the drag clicking guide.
Keyboard, touchpad and touchscreen notes
This tool counts mouse button presses only, so it is not a keyboard double click test. To check a key that repeats, use the spacebar counter and press slowly, watching for counts that jump by two.
A laptop touchpad click is reported to the browser as a mouse press, so you can test a touchpad button here in the same way. Results from phones and tablets are less useful, because taps are translated into mouse events by the browser rather than coming from a switch.

Frequently asked questions
How do I check if my mouse is double clicking?
Press START TEST above and click slowly, about once a second, for 50 to 100 presses. If the Double Clicks box goes above 0, your mouse sent two presses 100 ms or less apart when you pressed once, which means the button is double clicking.
Why is my mouse double clicking sometimes?
An occasional extra click is usually an early sign of a worn button switch, whose contacts bounce for longer than the mouse’s filter allows. Less often it comes from a low battery, a weak wireless connection or mouse software, so check those before replacing the mouse.
Can a double clicking mouse be fixed?
Sometimes. Settings, software, connection and dust problems are easy to fix, and some gaming mice let you raise the debounce time. If the switch itself is worn, the lasting fix is a new switch or a new mouse.
What does double click speed do?
It sets the longest gap allowed between two clicks for the computer to treat them as one double click. On Windows the default is 500 ms. A slower setting makes double clicking easier but can turn two separate single clicks into a double click.
Why does a fast double click not always count here?
This test only counts presses 100 ms or less apart, because it is built to catch faults. A normal double click you make on purpose is often slower than that, and your computer still accepts it because its limit is much longer.
Can I use this as a keyboard double click tester?
No. It counts mouse button presses only. For a key that seems to press twice, use the spacebar counter and press slowly while watching the count.
Does this test work with a wireless or Bluetooth mouse?
Yes. Any mouse your computer recognises works the same way. If a wireless or Bluetooth mouse double clicks, fit fresh batteries and move the receiver closer before you decide the switch is at fault.
