CPS Test
Count your clicks per second in a 1 to 60 second test, beat your best, and spot a mouse that double-clicks.

Click as fast as you can
Your clicks per second (CPS) appear when the 5 seconds run out.
On a phone or tablet, tap the box. Every finger that touches it counts as a click.
How to use CPS Test
- Pick a test length. 5 seconds is the usual one; 30 and 60 seconds test how long you can keep it up.
- Click in the box as fast as you can. The timer starts with your first click.
- When time runs out, read your clicks per second, your fastest second and the chart of how your speed changed.
- Click the box again to go again. Your best for each length is saved in this browser.
- If the result says clicks came too fast, check your mouse with the Mouse Test.
How it works
The test counts every press in the box: any mouse button, or a finger touching the screen. The timer starts with your first press and stops when the time is up; your score is the number of clicks divided by the seconds. Each press is timed by the browser itself, so a busy computer doesn’t slow your score down, and nothing leaves your device.
| Test length | What it shows |
|---|---|
| 1 second | A short burst: your top speed |
| 5 seconds | The usual test, and the one most CPS scores refer to |
| 10 seconds | The speed you can hold for a while |
| 30 and 60 seconds | Endurance: how much you slow down as your hand tires |
Reading the result
- Clicks per second (CPS): all clicks divided by the test length.
- Fastest second: the most clicks in any one-second stretch. It’s usually higher than your average, because most people start fast and slow down.
- The chart: your speed through the test. A falling line means your hand tired; dips in the middle often mean you changed grip.
- Best in this browser: your top score for each length, saved on this device only.
Clicking techniques
- Normal clicking: one finger, tapping the button.
- Jitter clicking: tensing your arm so your finger vibrates on the button.
- Butterfly clicking: two fingers taking turns on the same button.
- Drag clicking: sliding a finger along the button so the switch bounces. Only some mice do it.
Compare scores made with the same technique over the same length. Fast clicking is hard on your hand: take breaks, and stop if it hurts.
When clicks come too fast
A finger can’t press a button again within 20 milliseconds, so the test points out clicks closer together than that. Unless you were drag clicking, they usually mean a worn or dirty switch is sending two clicks for one press, the same fault that makes a mouse double-click files by itself. The Mouse Test checks each button for it and explains the fix.
Questions
How is CPS calculated?
Clicks divided by seconds. The timer starts with your first click, and every press of a mouse button (or touch on a screen) until time runs out counts: 37 clicks in a 5-second test is 7.4 CPS. Presses are timed by the browser, so a slow page doesn’t change your score.
What is a good CPS?
It depends on how you click: one finger clicking normally is slower than jitter or butterfly clicking, and scores drop in longer tests as your hand tires. Compare scores made the same way over the same test length, starting with your own best.
What is jitter clicking?
Tensing the muscles of your forearm and wrist so your finger vibrates on the button, which clicks much faster than a normal tap. It’s tiring, so keep sessions short and stop if your hand or wrist hurts.
What is butterfly clicking?
Clicking one button with two fingers, usually index and middle, one after the other. Each finger’s press counts, so you click about twice as fast as with one finger. Some games and servers limit it.
What is drag clicking?
Sliding a finger along the button so friction makes the switch bounce and send many clicks from one movement. It only works on some mice. It’s the same bounce a worn switch makes when a mouse double-clicks by itself, which is why the test points out clicks under 20 ms apart.
