Spacebar Speed Test
Mash the spacebar as fast as you can. We count keydown events and bucket them per second so you see both your sustained average and your peak single-second rate.
Press the spacebar as many times as you can.
You have 10seconds once you start. Keystrokes are captured globally — you don’t need to focus a field.
How it works
Pick a window (5, 10, 30, or 60 seconds) and start the test. Only the spacebar counts — other keys are ignored, and we call preventDefault on Space so the page does not scroll while you mash.
The counter ticks on every keydown event, including auto-repeat if you hold the key down. Per-second buckets feed the peak-CPS readout; CPS average is total presses ÷ window seconds.
Finger technique matters. A two-finger alternating tap (left-right-left-right) typically beats one-finger spamming by 30-50% for sustained CPS. Three-finger drumming can push higher but is rarely sustainable.

Frequently asked
What is a good spacebar CPS?
For sustained 10-second runs on a normal keyboard: 7–9 CPS is average, 10–12 is fast, 13+ is exceptional. Peak single-second rates often spike 2–4 above the sustained average. Numbers above 15 sustained almost always involve unconventional techniques or autoclicker assistance.
Does auto-repeat (key held down) count?
Yes — auto-repeat fires real keydown events and we count every one. If your goal is true tap-rate, do not hold the key down. The peak-CPS readout will make it obvious if you are auto-repeating: you will see one steady value rather than the spiky pattern of real taps.
Why is the spacebar specifically tested?
The spacebar is the most pressed key on any keyboard during typing, and its layout (centered, large, hit by the dominant thumb) makes it the canonical benchmark for sustained burst speed. CPS competitions and rhythm-game communities use it for the same reason.
Does my keyboard affect the score?
Yes — mechanical switches with short travel (light linears like reds, silvers) typically allow faster CPS than long-travel switches (browns, blues) or rubber-dome boards. Wireless keyboards on slow USB polling rates can drop key events under hard mashing.
