CPS test: click speed test

1. Pick the length of the test: 1, 5, 10, 30 or 60 seconds.
2. Click the box. Your first click starts the timer and counts.
3. Keep clicking as fast as you can until the time runs out.
4. Read your clicks per second. Press Copy link or Share to race a friend.

A short test shows your top speed, and a long one shows how long you can keep it up. Your best score for each length stays in this browser.

The browser times each click to the millisecond with its own event clock, so a slow screen never adds or loses a click. A click counts when the button goes down, not when it comes up.

Clicks less than 20 ms apart do not count. That is 50 clicks a second: no finger is that fast, but an autoclicker, a macro or a worn mouse button that bounces is. When many clicks come that fast, the page shows the score and does not save it.

• Rest your hand on the mouse and click with the tip of your finger, from the knuckle.
• Keep the mouse still: a mouse that slides makes you miss the box.
• On a phone, tap with two fingers in turn.
• Stop when your hand gets tired or sore.

Test the spacebar too with the spacebar clicker, or your reflexes with the reaction time test.
