Spacebar Counter

Count how many times you can hit the spacebar against the clock. The same clicks-per-second test, narrowed to a single key — no mouse, just the space bar.

Spacebar counter

Press Space to start0presses0.0 per second · 10s run

Press the Space bar to begin. The clock starts on your first press and stops itself automatically after 10 seconds — no click, tap or start button counts, only the Space bar.

Ready. This is a 10-second test — the clock starts on your first Space bar press.

presses per second, this run

Press the Space bar as fast and as steadily as you can. The clock starts on your first press and stops itself automatically once the duration you picked runs out, so there's no separate start button to find — just press, and the timer handles the rest. Your press count and presses-per-second rate update live while the clock runs, and a per-second bar chart afterwards shows exactly where you sped up, slowed down, or held a steady pace.

Why only the Space bar counts

This is deliberately narrower than a general click speed test. Every press is read as a keyboard event with code equal to "Space" — a mouse click, a screen tap and an Enter-key press on a button all do NOT register here, even though they would all count on a click speed test. That narrowness is the point: if you're checking a specific key's switch — a laptop spacebar you suspect is wearing out, a mechanical keyboard's largest and most-used key, or just want to know your pure one-key press rate without a mouse in the mix — this test isolates exactly that key and nothing else. Holding the key down also doesn't inflate your count: the operating system's own key-repeat, which fires while a key stays pressed, is filtered out so only genuine up-then-down presses are counted.

Picking a duration

A five-second run is close to pure burst speed — however many presses you can land before the timer cuts off, with almost no room for fatigue to matter. A thirty- or sixty-second run instead rewards a rhythm you can hold for the whole window, since early fatigue and any drop in form drags the average down far more than it would on a short burst. Neither length is the "real" test — they answer different questions about how you press, which is why comparing a five-second score against a sixty-second score tells you very little. The duration tabs above are separate, individually bookmarkable pages, so bookmark whichever one you actually practise on and come back to that same page each time.

Reading your result

Your best run in this browser is kept in localStorage, scoped to this exact duration, and shown alongside the date it was set — nothing is sent anywhere, and clearing your browser's site data clears this history too. The per-second bar chart after each run is often more informative than the headline count alone: a flat, even set of bars means a genuinely held rhythm, while a tall first bar followed by a fading tail usually means you burned out early rather than pacing yourself for the whole run. If your bars look erratic rather than gradually declining — spikes and gaps rather than a smooth taper — that pattern is also worth a second look with the keyboard tester's key-log, since it can point at a switch problem rather than a pacing one.

Questions

How is a spacebar counter different from a click speed test?
A click speed test (CPS test) counts a browser click, which fires the same way whether it comes from a mouse, a touchscreen tap or an Enter/Space press on a focused button — it doesn't care which input produced it. This tool counts one specific thing: a physical press of the Space bar, detected as a keyboard event rather than a click. That distinction matters if you're testing a keyboard's spacebar switch specifically — its debounce, its travel, whether it double-fires — rather than testing your general clicking speed with whatever pointing device is in your hand.
Why doesn't tapping the screen count as a press?
Because this test measures the Space bar itself, not a generic tap or click. A touchscreen phone or tablet with no attached keyboard has no physical space bar to press, so there is nothing for this specific test to measure on that device — tapping the widget wouldn't tell you anything about a spacebar switch that doesn't exist. If you connect a Bluetooth or USB keyboard to a touch device, its Space key works exactly the same as it would on a laptop, and the test picks it up the moment you press it.
Why did some of my spacebar presses not get counted?
Two things are filtered out on purpose. Holding the Space bar down triggers the operating system's own key-repeat, which fires repeated keydown events for a single physical press — those are ignored, since they represent one press held rather than several presses made. And a press that lands after the clock has already run out doesn't count, even if you were mid-press when the timer hit zero, because the run has to stop at a fixed, repeatable point rather than accepting one more press depending on exact timing. Neither exclusion should be common in normal use; if your count looks consistently low, check that focus is on the page and not inside a text box, since a press typed into a form field is deliberately not captured.
What's a good spacebar counter score?
It depends heavily on the duration, which is why this tool keeps a separate best for each one rather than a single all-time number. A five-second burst rewards raw finger speed with almost no time for fatigue to set in, so scores there run higher per second than a sixty-second run, where an early pace has to hold up for the whole minute. Most people land somewhere in the same six-to-nine-presses-per-second range that applies to single-finger clicking generally; scores well above that usually come from a deliberate technique — alternating fingers, or bracing the hand so it vibrates against the key — rather than a faster single finger.
Does this test show if my spacebar is going bad?
It can surface one specific symptom: a switch that's starting to double-fire or drop presses under fast, repeated use will show up as an erratic per-second bar chart — bars that spike or flatten out of step with a steady pressing rhythm you know you kept. It isn't a full diagnostic on its own, though. If you suspect a genuinely failing switch, pair this with the keyboard tester's ghosting and key-log checks, which show every individual key event rather than just a running count for one key.
