Double Click Test

Check whether one mouse press is registering twice with this mouse double click test. Test one button at a time, inspect the intervals, then retest after a simple environment change.

Runs locally in your browser — raw events are not uploaded.

Mouse double click test

Methodology 0.1-preview · browser-observed events only
● Events stay in this page
Choose one button. Auto locks to the first mouse press.
Press once at a time

Do not intentionally double-click. Only complete mouse down/up pairs from one button are analysed.

Collecting observations

What this test measures

Intervals only use consecutive, same-button mouse pointerdown events with a matching pointerup.

A deliberate test, not a speed game

How this double click tester works

Press once at a time inside the test area. The tool compares successive mouse button-down events for the same button, so left and right clicks never get mixed together.

1

Choose a button

Use Auto to lock the first button you press, or select Left, Right or Middle before starting.

2

Collect 25 presses

Keep a natural pace. Touch, pen and keyboard-activated clicks do not enter the sample.

3

Retest with one change

If repeated input is observed, change browser, port, receiver position or computer and run another round.

What this can and cannot tell you.

This page observes browser events; it cannot inspect a mouse switch, identify your mouse model, or confirm an electrical fault. A clean round does not exclude an intermittent problem. On a phone or tablet, a detected pointer is labelled “mouse-like input” because browsers cannot reliably identify the physical device.

Double click checker FAQ

Does a fast interval mean my mouse is broken?

No. It is an observation that should be retested after changing one environment factor. Software mappings, connections and a specific app can also affect what you see.

Why is my touch screen not counted?

Touch and pen input do not test a mouse switch. You can still browse this page; connect a mouse and click in the test area to begin.

Does this save my clicks?

No. Raw browser events and checklist choices stay in page memory and disappear when you refresh.
