👆👆 Double-Click Test

Check whether your mouse double-clicks reliably, measure your double-click speed, and spot signs of an unintended "ghost" double-click caused by a worn-out button switch.

How This Test Works

A double-click is two clicks made close enough together in time that your operating system treats them as one action.

  1. Double-click inside the box below, just as you normally would to open a file or folder.
  2. We measure the exact time gap between your two clicks, in milliseconds.
  3. Repeat a few times to see your average double-click speed and consistency.
  4. If a gap comes back extremely short (under ~60ms — faster than a human can deliberately click), it's flagged as possible button chatter rather than a genuine double-click.
Why this matters: A reliable double-click depends on both your clicking speed and a healthy mouse switch. If your intervals are consistently very short (well under 60ms) without you clicking unusually fast, or if single clicks sometimes register as double-clicks on their own, your mouse button may be "chattering" due to wear — the same issue tested in more depth on the Hold & Drag Test page. Most operating systems also let you adjust the double-click speed threshold in your mouse settings if double-clicks feel too fast or too slow to register.
