Double Click Test

How to use it

1. 1

   Click the pad ten times, slowly and deliberately, leaving a clear gap between clicks.

2. 2

   Type 10 into "Clicks you meant to make". The page then shows how many extra presses arrived.

3. 3

   Read the list. Every press appears with the gap since the one before it, so an unintended press shows up as a very small gap.

4. 4

   Repeat a few times. A failing switch is usually intermittent, so one clean run proves less than three do.

Reading the list

The useful comparison is the one you make yourself: presses received against clicks intended. If you clicked ten times and the page logged twelve presses, two arrived that you did not make, and the gaps in the list show where.

This page deliberately does not tell you that a gap below some number of milliseconds is a fault. No manufacturer publishes such a threshold, and operating systems differ in what they treat as a double click, so any line drawn here would be invented. What the page can say honestly is what arrived and when.

What it cannot tell you

A browser sees events, not switch contacts. A fast, deliberate double click from a steady hand and a bouncing switch look the same in the log, which is why the count you provide matters. It also cannot repair a switch: a mouse that doubles consistently usually needs the switch replaced, and cleaning helps only when dust is the cause.

To check the buttons themselves, use the Mouse Tester; for how fast you can click on purpose, the Click Speed Test.
