How does the CPS test work?
Choose 5 or 10 seconds, then click or tap the box as fast as you can. The clock starts on your first click, so getting ready costs nothing, and stops when the time is up. You can use the Space bar instead of a mouse, but whichever you start with is the only input that counts for that run, so you can't add a thumb on Space to a hand on the mouse.
How is CPS calculated?
CPS, clicks per second, is your clicks divided by the seconds of the test: 40 clicks in 5 seconds is 8 CPS. Each click is timed by your browser the moment the button goes down, and only clicks that land before the deadline count. You also see your fastest second: the most clicks you fitted into any one-second stretch, which is usually higher than your average because almost everyone slows down towards the end.
Is 5 or 10 seconds better?
They measure slightly different things. 5 seconds is close to a sprint, so it shows your top speed. 10 seconds includes the point where your hand starts to tire, so it usually comes out a little lower and is a fairer test of how long you can keep the pace up. Compare runs of the same length.
How to click faster
- Relax your hand. A tense arm tires within seconds. Fast clickers rest the hand on the mouse and move only the finger.
- Use small presses. The button only has to go down far enough to click; pressing harder than that wastes time on every click.
- Jitter and butterfly clicking. Gamers use tricks such as tensing the forearm so the finger vibrates (jitter clicking) or alternating two fingers on one button (butterfly clicking). They raise the count, but stop if your hand or wrist hurts.
What can change your result
- The mouse. A mouse ignores its button for a few milliseconds after each click, so that one press can't register as two. On mice where that pause is long, it caps how fast you can go.
- Phone or mouse. Tapping a touchscreen with two fingers is a different movement from clicking, so phone and computer results aren't comparable.
For how quickly you react rather than how often you can click, try the Reaction Time Test; for aiming, the Mouse Accuracy Test.
