Spacebar counter

Pick a time limit and start pressing Space. The counter shows three numbers live: presses so far, presses per second (SPS) and the time left. When the time runs out, you get a chart that shows how many presses you made in each second, so you can see whether you started fast and faded or kept a steady pace.

The unlimited mode has no timer. It simply counts every press, which is handy if you want to count something by hand or test how long you can keep going. Press Esc or the Restart button to set it back to zero.

On a phone or tablet there is no space bar to press, so tap the big button instead. Every tap counts as one press.

Mode	Good for
5 seconds	A pure speed burst; the most common way to compare with friends
10–15 seconds	Speed with a little stamina
30–60 seconds	Endurance: can you hold your pace?
Unlimited	Free counting with no clock

Short tests always give a higher SPS than long ones, because your hand tires. Compare scores within the same mode only. That is why the leaderboard keeps a separate list for each length.

When you hold a key down, your computer starts repeating it after a short delay. Hold Space in a text box and you get a long row of spaces. A naive counter would count each of those repeats and hand you an impossible score.

This counter ignores auto-repeat. It counts a press only when the key actually goes down again after being released, so holding Space does nothing. Your score reflects how fast you really move your finger.

Worked example: you choose 10 seconds and press 58 times. Your score is 58 ÷ 10 = 5.8 presses per second. In the 5-second mode the same speed would show as 29 presses.

• Use your thumb or alternate two fingers. Some people tap with one thumb, others alternate both thumbs or two fingers. Try each and keep what scores best for you.
• Keep the motion small. Lift your finger only as far as the key needs to reset; big swings waste time.
• Relax your wrist and shoulder. Tension builds up quickly and slows you down in the 30- and 60-second modes.
• Warm up with a few short rounds before a serious attempt.
• Mind your keyboard. A long space bar can feel different at its ends than in the middle. Find the spot where it presses most evenly.

Take breaks. Fast repetitive tapping for a long time can strain your hand and wrist; stop if it hurts.

If the count seems lower than your taps, the switch under the space bar may be sticking or dirty. If it jumps by two on a single press, the switch may be chattering. To check, open the keyboard test: it shows every key event and flags suspected double presses.

Want to test other kinds of speed? Try the CPS test for mouse clicks, the typing speed test for words per minute, or the reaction time test for reflexes.
