Mouse Test & CPS Test

Point at the button area and click single clicks at a normal pace for a minute. Every time the same button is pressed twice within 80 ms, the page lists it as a suspicious double click with its timing. Several of these mean the switch is worn.

Choose a length (1, 5, 10, 30 or 60 seconds) and click the box as fast as you can; the timer starts with your first click. You get clicks per second, your best and average for that length, the time between clicks and a chart of your click timing. Best scores are kept in this browser only.

Around 6–7 clicks per second is typical. Above 10 is fast, and techniques like jitter or butterfly clicking can go higher. Very short gaps between clicks (under about 30 ms) usually come from a switch double clicking rather than from your finger.

The browser tells the page each time the mouse reports movement, including reports it groups together. Moving the mouse quickly gives enough reports to estimate the rate. It is an estimate: the browser, the system and the screen can merge or cap reports, so a 4000 or 8000 Hz mouse may read lower.

Many mice send Back and Forward as buttons 4 and 5, which the page shows. Some mice instead send keyboard shortcuts or need their own software to map them; then nothing shows here and the keyboard test may show the key instead.

Pointer lock hides the cursor and shows the raw movement the mouse sends, which games use. With a pen or touch screen the page shows the pointer type, pressure, tilt and how many fingers touch at once.

No. Clicks and movements are processed in your browser only; nothing is uploaded. Your best CPS scores are saved in this browser’s storage.
