CPS Test (Click Speed Test)

What a CPS test measures

CPS stands for clicks per second. This click speed test counts how many times you press during a round you choose, then divides that total by the length of the round. You can run it with the mouse or switch to the spacebar, which turns the same page into a spacebar counter. It's free, there's nothing to install or sign up for, and your scores stay in your own browser rather than on a server.

People land here for different reasons — a game that rewards fast clicking, a new mouse they want to feel out, or plain curiosity about what their hand can do. In every case, one round tells you very little. A handful of rounds under the same conditions tells you a lot.

How to play

1. Pick a duration. 1, 5, 10, 30, 60 or 100 seconds.
2. Pick an input. Mouse clicks or spacebar presses.
3. Start and go. The clock begins on your first real press, not when you hit start, so the seconds you spend settling your hand cost you nothing.
4. Read the result. You get clicks per second to one decimal place plus the raw click total. Beat your previous best for that duration and input and the new score is saved.

A few rules worth knowing:

• Only the left button counts. Right, middle and side buttons are ignored.
• Every finger is tracked separately, so alternating two fingers (butterfly clicking) is counted exactly as you do it.
• In spacebar mode, auto-repeat from holding the key down is thrown away. Only genuine press-and-release actions count.
• For a moment after the round ends, input is ignored. That stops a still-clicking hand from hitting "play again" and starting a round you weren't ready for.

How scores are stored

Your best is kept separately for each duration and each input method, so a 10-second mouse score never overwrites a 10-second spacebar score or a 1-second burst. It lives in the browser you played in, which means a private window or a second device starts empty, and clearing this site's data wipes it.

That's also why this page won't tell you whether you beat "the average". The averages floating around online were measured over different durations on different hardware, and none of them can be checked. Your own record, measured at the same duration, with the same input, on the same mouse, is a baseline you can actually trust.

Getting faster

• Choose a duration and train it. A one-second burst and a sixty-second grind are different skills. Pick the one you care about instead of splitting your practice.
• Click with the finger, not the arm. Moving the whole arm burns out fast. Rest the wrist on the desk or mat and keep the motion to short movements of the fingertip.
• Try alternating two fingers. Index and middle alternating usually holds up better than a single finger once rounds run past thirty seconds.
• Loosen your grip. Squeezing the mouse stops the button travelling all the way down, and you get misses. If your click total feels lower than the effort you put in, this is usually why.
• Stop if your wrist hurts. Jitter clicking — tensing the arm so the finger vibrates — does push the number up, and it is hard on the wrist and forearm. No score is worth an injury.
• Keep the setup constant. Change the mouse, the chair height, your posture or the duration and the number moves. If you want a comparison, change nothing.

Common snags

The timer isn't moving. It waits for your first press. One click and it runs.

My phone gives a different number. Touchscreens and mice register presses differently, so the same person scores differently on each. Compare runs on one device rather than across devices.

What about autoclickers? The number goes up and the measurement stops meaning anything about your hand. Nothing is uploaded and there's no leaderboard here, so the only score worth keeping is one you measured honestly.

My best score vanished. Either the browser's site data was cleared, or you opened the page in a different browser or on a different device.

Other tests to try

Clicking fast and reacting fast are not the same skill. To see how quickly you respond the moment a signal changes, take the reaction time test — it runs five attempts and averages them. If you want help making sense of the milliseconds it gives you, we wrote a longer explainer on reading those numbers.

For speed plus precision, the aim trainer puts thirty targets in front of you and tracks both hit time and accuracy. And when your hand needs a rest, the bulls and cows number puzzle swaps reflexes for deduction. Other brain tests, like a memory test, are on the list for later.

CPS Test FAQ

What does a CPS test measure?

CPS stands for clicks per second. The test divides the total number of clicks you make by the length of the round, and the result screen shows both the total and the clicks-per-second figure.

What is a good CPS score?

Averages quoted online come from sources that can't be checked, so this page doesn't rank you against them. What it does keep is your own best score for each duration and input method, saved in your browser, which is a far more honest baseline. A 1-second round always looks faster than a 60-second one, even for the same hand.

Can I use the spacebar instead of the mouse?

Yes. Switch the input mode to spacebar and the test counts key presses instead of clicks. Holding the key down does nothing, because auto-repeat is ignored; only real press-and-release actions count.

Which durations can I choose?

1, 5, 10, 30, 60 and 100 seconds. Short rounds show your burst speed, long rounds show whether you can hold it. Best scores are stored separately for each duration and each input method, so they never mix.

The timer doesn't move when I press start. Is it broken?

No. The clock starts on your first real click or key press, not when you press start, so the time you spend getting your hand into position costs you nothing.

Where is my best score saved?

Only in the browser you played in. A private window, another browser or another device each keep their own record, and clearing this site's data removes it. Nothing is sent to a server.

Do autoclickers or jitter clicking count?

A macro or a mouse with a turbo button will raise the number, but it stops being a measure of your hand. There's no leaderboard here and nothing is uploaded, so the only score worth having is one measured the same way every time. Jitter clicking is hard on the wrist, so keep those rounds short.

Does it work on a phone?

Yes. Taps are counted the same way, and if you alternate two fingers each one is tracked separately. Touchscreens and mice behave differently, so compare runs on the same device rather than across devices.
