Click Speed Test — CPS Test

What the Click Speed Test measures

It counts how many click events the box registers while the timer runs (5, 10, 15 or 30 seconds, your choice) and divides that by the time that really elapsed. The result is CPS, clicks per second. After you press Start test there is a 3-2-1 countdown, so the click that starts the test doesn't count, and the timer only starts when the box goes live.

How a run works

1. 01

   Pick a duration

   Shorter runs reward a fast burst; longer ones show whether you can hold the pace. You can only change it between runs.

2. 02

   Press Start test and wait for the countdown

   You get three seconds to get your hand ready. Nothing is counted yet.

3. 03

   Click inside the box

   Every click event counts. The live readout shows your clicks, the time left and a running CPS.

4. 04

   Read the result

   You get the total clicks, the CPS and the duration that was actually measured. Your best score is kept in this browser only, as a single figure shared by all four durations.

Reading your score

The formula is plain: clicks divided by seconds. Sixty-two clicks in a measured 10.01 seconds is 6.19 CPS. The duration in the result is the one measured with performance.now(), which is why it can read 10.01 s instead of exactly 10.

Compare like with like. A 5-second run tends to give a higher CPS than a 30-second one because a burst is hard to keep up, so only compare scores with the same duration, on the same device and with the same way of clicking. Scores also vary from one attempt to the next, so a single run is a snapshot, not a rating.

That also applies to “Your best”. It is one value for all four durations, not one per duration, so a 5-second burst will often hold it and a 30-second run may never beat it. If you want to track progress, write down the duration next to each score you keep.

If a score looks impossibly high for how you clicked, one press may be registering twice. The Mouse Test shows the raw presses, and the double-click guide explains how to tell a button that registers an extra click from a quick double click of your own.

What this score is not

CPS here means one thing: how many click events your browser registered, divided by the measured duration. It isn't your mouse's polling rate, DPI or switch speed, and it says nothing about the hardware itself. The box is a standard button, so anything that produces a click event counts: a mouse, a trackpad tap, a touch, or Space or Enter while the box has focus. Results differ between browsers, input methods and devices, so a trackpad score and a mouse score are not comparable.

What to do next

For fair comparisons, choose one duration and keep it, rest your hand between runs and use the same device. If the numbers jump around or look wrong, check the buttons with the Mouse Test. To see how quickly you respond to something appearing on screen, rather than how fast you can repeat an action, try the Reaction Time Test.
