Mouse Test
Check every browser-visible button, then make 20 slow single presses to screen double-click patterns without relying on a raw counter.
- Fewer clicks, keyboard friendly
Button and wheel check
Press each available mouse button and roll the wheel inside the test area.
Click, hold, and scroll here
Totals stay cumulative until reset. A button’s number grows while it is held, and wheel movement is counted by direction.
Guided double-click screen
Make 20 deliberate single presses, about one second apart. Do not intentionally double-click.
Make slow single Left button presses here
This screen compares only the selected button. It marks a repeat below 80 ms for you to inspect; it is not a hardware verdict.
Ready. Make a slow single Left button press to begin.
Pointer events and results stay in this browser tab. This page observes browser input; it cannot certify mouse hardware.
How to use
- Press each available button and roll the wheel inside Button and wheel check.
- Choose Left, Middle or Right in Guided double-click screen.
- Make slow, intentional single presses about one second apart until the sample reaches 20.
- If a repeat is screened, run a fresh sample and compare the mouse on another computer before treating it as a hardware fault.
What this double-click screen measures
This page records browser-observed pointer presses, not the electrical signal inside a switch. It compares each press only with the preceding press of the same selected button. A gap below 80 ms is marked for review because the controlled instructions ask for slow single presses. The 80 ms value is this page’s screening rule, not a universal definition of a failed mouse or a replacement for a manufacturer diagnostic.
Why the guided sample uses 20 slow presses
A deliberate pace makes the result easier to interpret than clicking as fast as possible: a count that jumps or a very short same-button gap is visible in a bounded sample. Twenty browser-observed presses are enough to repeat the same short check after changing a USB port, battery, receiver or computer. A clean sample does not prove that an intermittent fault is absent; repeat it when the real symptom occurs.
Browser button limits to expect
Pointer events expose standard button codes: main (usually left) is 0, middle is 1, secondary (usually right) is 2, back is 3 and forward is 4. Button assignments can change for left-handed settings or vendor software. Side buttons mapped to macros may never reach a browser, and a browser may still reserve their back or forward action. This test therefore reports what the browser receives, rather than declaring every unreported physical button broken.
Frequently asked questions
How do I test whether my mouse double-clicks on one press?
Choose the affected button, then make 20 slow single presses about one second apart in the guided screen. A same-button gap below 80 ms is marked for review. Repeat the sample and test the mouse on another computer before concluding that the switch is faulty, because this page observes browser input rather than internal hardware signals.
Does a sub-80 ms repeat prove my mouse switch is broken?
No. A sub-80 ms repeat is a screening result under this page’s deliberately slow test instructions, not a hardware diagnosis. Repeat the 20-press sample, check the wireless battery or receiver and compare another computer or application before deciding whether to repair or replace the mouse.
Why do my mouse side buttons not appear in the test?
Browsers receive side-button presses only when the operating system or mouse driver exposes them as standard Back (3) or Forward (4) inputs. A macro, DPI-shift or vendor-specific mapping may not reach the page, so an unchanged counter does not by itself show that the physical button is broken.
Can I use this mouse test on a touchscreen or trackpad?
The button and wheel counters are intended for a physical mouse. Pointer events can also come from touch or a pen, so this page ignores non-mouse pointer input in its test pads. A trackpad may expose only a primary click and cannot verify the wheel, middle or side buttons of a mouse.
