How the counter works
Choose Free or a round of 10, 30 or 60 seconds and press Start. The counter moves focus into the panel and waits; the first press of the space bar starts the clock and counts as one. The big number in the panel grows with every press, the caption shows the seconds left in a timed round or the time elapsed in a free count. A timed round stops by itself, and the result card shows the count, the rate per second and your best for that round on this device. A free count runs until you press Stop.
The space bar is read on the whole page while the counter runs, not only on the panel, so it does not matter where the focus ends up. Auto-repeat from holding the bar down is ignored, and the browser's own use of Space, scrolling the page and activating a focused button, is held back so a fast round cannot scroll you away or stop itself. On a touch screen, a tap on the panel counts as a press.
The preview panel above the button draws one bar per second of your last round, so you can see whether you started fast and slowed down or kept a rhythm to the end.
What the result means
The result is the number of presses. For a timed round the context line adds presses per second and your best for that round length; for a free count it adds the rate and the time it ran.
- 50 to 70 in 10 seconds. A normal thumb. Enough for any game or typing rhythm.
- 70 to 90. A fast thumb or two thumbs alternating.
- Above 100. The tricks of click-speed games, or a mechanical keyboard with very light switches. Enjoy, and rest the hand afterwards.
- A count that stops rising while you keep pressing. Either the key is not registering every press, which the keyboard test will show, or the operating system's key repeat started because the bar was held rather than tapped.
- A second round noticeably lower than the first. Fatigue. Rest between attempts; a sore thumb is the only thing a spacebar counter can damage.
Getting a higher count
Rest the heel of the hand on the desk and tap from the thumb joint, not the wrist. Alternating two thumbs roughly doubles the count once the rhythm is even. Light switches and a short travel help; a laptop keyboard with a deep, rubbery bar is the slowest. Keep rounds short and stop when the thumb aches. If a keyboard drops presses at speed, that is its debounce or its scanning rate, not you; the keyboard test shows which keys register and how many held at once.
When the space bar itself is the problem
A space bar that needs a hard press at one end, rattles, or registers only every other tap has a worn stabiliser or switch. On a mechanical keyboard the stabiliser can be cleaned and lubricated and the switch replaced; on a laptop the whole keyboard is usually swapped. A new keyboard with a space bar that misses presses is defective and should be exchanged within the return window; a worn one under warranty is a repair claim, and a screenshot of the keyboard test with the bar left dark after pressing it is the evidence a service centre wants.
Frequently asked questions
How many spacebar presses in 10 seconds is good?
Around fifty to seventy with one thumb is typical, which is five to seven presses a second. Two thumbs alternating push past ninety, and the tricks from click-speed games, such as vibrating the whole hand, can reach one hundred and twenty. The 30 and 60 second rounds fall off from there because nobody keeps that pace.
Can I use another key, or tap on my phone?
Only the space bar counts on a keyboard, because that is the game. On a phone or tablet, tapping the counter panel counts as a press, so the same rounds work with a thumb on the screen. A mouse click on the panel does not count.
Why did the page not scroll when I pressed Space?
While the counter runs, the page holds back the space bar's usual job of scrolling and of activating a focused button, so a fast round does not scroll you away or stop the count. Press Stop, or wait for the round to end, and Space behaves normally again.
Does the counter accept key repeat when I hold the bar down?
No. Holding the space bar makes the operating system repeat the key many times a second, and those repeats are ignored; only a fresh press counts. That keeps the score about your thumb, not about the repeat rate setting.
Where is the best score kept?
In your browser's local storage on this device, one number per timed round. It never leaves the device, is not sent anywhere, and is gone if you clear site data or use a private window. The free count keeps no record because it has no fixed length.
