How Fast Is Your Double Click?
Measure the time interval between your double clicks in milliseconds. Detect whether your mouse registers double clicks reliably and identify switch bounce or debounce problems — all processed locally in your browser.
This test measures the time gap between two consecutive clicks in a double-click action, using PointerEvent timestamps with sub-millisecond precision to detect interval consistency and switch reliability.
The default Windows double-click speed threshold is 500ms. Most users double-click in 80–150ms, while the OS double-click detection window is configurable from 200ms to 900ms.
What Do Your Results Mean?
| Result | Range | Meaning |
|---|---|---|
| Good | Consistent intervals of 50–150ms | Your double-click timing is fast and consistent. Your mouse switch is registering reliably with no bounce or missed clicks. |
| Warning | Intervals vary by more than 50ms between attempts | Inconsistent double-click intervals may indicate an aging mouse switch or incorrect OS double-click speed settings. Check your mouse configuration. |
| Poor | Frequent missed double clicks or intervals under 20ms | Extremely short intervals (under 20ms) suggest switch bounce — your mouse is registering phantom clicks. Intervals that frequently exceed your OS threshold mean double clicks are not being recognized. |
Common Issues & Solutions
Mouse registers single clicks as double clicks (phantom double-click)
This is a classic sign of switch bounce from a worn-out microswitch. Increase the debounce delay in your mouse software, or replace the mouse switch if the problem persists.
Double clicks are not registering in the OS despite fast interval
Your OS double-click speed setting may be too fast. On Windows, go to Settings → Devices → Mouse → Additional mouse options and slow down the double-click speed slider. On macOS, adjust in System Preferences → Mouse.
