Click Speed Test

How to use it

1. Choose the Test length and the Input you want to use.
2. Press for the first time to start the timer, then press as fast as you can.
3. When time is up, read Clicks per second, the Average gap between clicks and the Jitter.
4. Press Try again to repeat the test and compare your results.

What the rate means

Clicks per second (CPS) is the number of presses counted in the test divided by the length of the test in seconds. The first press starts the timer, and every press up to the end of the test counts. A 10-second test with 62 presses gives a rate of 6.20 clicks per second.

CPS = clicks counted ÷ test length in seconds.

Gaps, jitter and rhythm

A gap is the time between two presses, measured in milliseconds with the browser's high-resolution clock. The average gap is the mean of all gaps. Jitter is their standard deviation: how far the gaps spread from that average. A steady rhythm has a low jitter even at a high speed. Methods such as butterfly clicking (fast alternating taps with two fingers) or jitter clicking (shaking the hand) make the rhythm less even, so they usually show more jitter.

Switch bounce and double registration

A mechanical switch can close more than once when it is pressed. The extra closures show up as gaps of a few milliseconds, which this test counts separately so that you can see them. Such gaps are not clicks you made. Many gaps under 30 ms can mean that a switch is worn.

What the browser measures

The browser sees a press when the page receives it. Mouse software that sends clicks in bursts, or a slow device, can change the figures, so the result measures the page as much as the mouse. Repeat the test a few times before you draw a conclusion.
