Measured in presses per second ยท higher is better
Spacebar Counter
Hit space as fast as you can. Pick a duration, or run it untimed and just count.
Before you start
The median on mouse is 6.80 PPS. Run the test and we will place you against it.
Compared against
Keyboard switch type changes this number as much as skill does. Compare only across the same keyboard.

Curve is a fitted baseline plus 0 first attempts recorded here. The baseline is a curve, not a sample: no part of it is a real person. Baseline is an estimate: centred on the same range as mouse click speed, since both are limited by the same muscles. No published dataset was found for it. Per-device offsets are extrapolated, not measured. The baseline is dropped once a device class holds 5,000 real first attempts. See the full distribution.
Understanding your score
| Band | PPS | What it means |
|---|---|---|
| Exceptional | 12.00 and above | Usually a specific technique rather than raw speed. |
| Very fast | 9.00 to 11.99 | Top few percent. |
| Fast | 7.50 to 8.99 | Clearly above average. |
| Average | 5.50 to 7.49 | Where most results land. |
| Below average | 3.50 to 5.49 | Common on laptop keyboards with long travel. |
| Slow | 3.49 and below | Check that key repeat is not interfering. |
Presses per second, not total presses
The headline number is your total count, because that is what people come here to see. The ranked number is presses per second, because a 60 second run and a 5 second run produce totals that cannot be compared to each other.
Expect your rate to be highest over 5 seconds and to fall as the duration grows. Sustained spacebar pressing is limited by forearm endurance rather than by nerve speed, and most people lose 20 to 30 percent of their opening rate by the end of a 60 second run.
How the count is taken
Only keydown events count, and held keys are ignored. Holding the spacebar down triggers your operating system key repeat, which would otherwise generate a stream of events you did not actually produce. Each press must be a real press and release.
The clock starts on your first press, not when the page loads. There is no reaction time component in this number and no advantage to hovering over the key.
What limits the number
Keyboard travel. A low-travel laptop or optical switch keyboard returns noticeably higher rates than a deep mechanical board with heavy springs. The difference between hardware is comparable to the difference between people.
Technique. Alternating two fingers or two thumbs beats a single finger by a wide margin. Some people brace the hand and vibrate the whole forearm, which produces the very high results and is hard on the wrist.
Endurance. Past about 15 seconds the limiting factor stops being how fast you can move and becomes how long you can keep moving that fast.
What the browser can and cannot see
A key press reaches this page as a keydown event with a timestamp. What the page never learns is when the switch physically closed. Between those two moments sit the keyboard controller, USB polling, the operating system input stack, and the browser event loop, and together they add a small, mostly constant delay.
Because the delay is roughly constant it barely affects a rate measured over ten seconds. It would badly affect a single-press latency measurement, which is why this page reports a rate and not a latency.
Browsers also deliberately reduce the precision of event timestamps as a defence against timing-based fingerprinting. That coarsening is far smaller than the gap between two human presses, so it does not affect the count.
Questions
- Does keyboard latency affect my presses per second?
- Barely. Input latency is roughly constant, so it shifts every press by the same small amount and largely cancels out over a ten second run. It would matter for a single-press latency test, which is not what this measures.
- What is a good spacebar speed?
- Around 6 to 7 presses per second is typical over 10 seconds. Above 9 is genuinely fast. Above 12 usually means a specific technique such as vibrating the forearm rather than pressing with a finger.
- Does holding the spacebar down count?
- No. Only real key presses register. Key repeat from a held key is filtered out, so you cannot inflate the count by holding.
- Why is my rate lower over 60 seconds?
- Because sustaining it is a stamina problem, not a speed problem. Most people lose a fifth to a third of their opening rate over a minute. That is normal and it is why the durations are ranked separately.
