What is a Spacebar Speed Test?
A Spacebar Speed Test measures accepted physical Space key presses during a fixed configured duration. Spacebar CPS means accepted Space presses ÷ configured seconds. The first accepted press starts the timer and counts, and every later accepted press requires a release first.
Holding Space and browser auto-repeat do not add presses. Only the Space key is measured; this is not typing or WPM, reaction time, generic Keyboard CPS, an untimed counter, or a game. Browser events also cannot diagnose a keyboard, switch, complete input latency, ghosting, rollover, or a broken key. It is not an ADHD screening, TOVA, clinical continuous performance, attention-assessment, or other medical or psychological test.
How to take the Spacebar Speed Test
- Choose a preset or Custom duration.
- Keep Single Test selected for a normal timed run.
- Press Start test.
- Press and release the physical Space key.
- The first accepted press starts the timer and counts.
- Continue until the configured duration ends.
- Review Spacebar CPS, timing results, History, and Personal Best.
New here? Start with the 10-second default and Single Test. Every accepted press requires keydown followed by keyup. Holding Space or browser repeat does not add presses. Space inside an editable control does not count; Space while idle is not blocked, and the on-screen keycap is only a visual cue.
Choose a duration and test type
1 second
The shortest preset. It enables Best of 5 and is highly sensitive to individual press timing.
5 seconds
A short Single Test.
10 seconds
The default and recommended starting point.
30 seconds
A longer sustained Single Test.
60 seconds
The longest preset for sustained Spacebar pressing.
Custom
Enter whole seconds from 1 to 300. Custom 1 enables Best of 5; every other value uses Single Test.
- Single Test
- One attempt at any valid duration, with one complete result. History and Personal Best are bucketed by duration and variant.
- Best of 5
- Five one-second rounds after one Start. Each round has a one-second preparation; an interrupted series is discarded and one compact summary is saved after Round 5.
For repeat comparisons, use the same duration and test variant. A 1-second Single Test, a 60-second Single Test, and a 1-second Best of 5 series are different test conditions and should not be treated as interchangeable scores.
How to read your Spacebar CPS result
Spacebar CPS = accepted Space presses ÷ configured seconds
45 accepted Space presses in 10 seconds: 45 ÷ 10 = 4.50 Spacebar CPS.
The configured duration—not the interval between the first and last press—is the final denominator. Live Spacebar CPS uses elapsed time for changing in-test feedback. Final Spacebar CPS uses the full configured duration and is the value eligible for a Personal Best; the live rate is not saved as a formal PB.
- Peak 1s Spacebar CPS
- The highest accepted press rate in the existing sliding one-second window, not the overall Spacebar CPS.
- Average Interval and Fastest Interval
- The mean and shortest time between adjacent accepted presses. Both display a dash with fewer than two accepted presses.
- Consistency
- The existing bounded timing-stability score. It is not accuracy, skill, health, or keyboard quality.
- First-half and Second-half CPS
- Accepted press rates in the first and second halves of the configured duration.
- Fatigue Change
- Fatigue Change = (secondHalfCps − firstHalfCps) ÷ firstHalfCps × 100. It is unavailable when firstHalfCps is zero and describes only this attempt, not medical fatigue or ability.
- Per-second chart
- Fixed one-second press buckets across the configured duration; no additional timeline is collected.
How 1-second Best of 5 works
- Select 1 second.
- Select Best of 5.
- Press Start test once.
- Wait through the one-second preparation for Round 1.
- The first accepted Space press starts Round 1 and counts.
- Preparation for the next round starts automatically.
- Continue through Round 5 without pressing Start again.
- After Round 5, one compact series summary is saved.
Release Space before the next accepted press; browser auto-repeat does not count. Blur, a hidden page, pagehide, Reset, or Cancel series discards the unfinished series. The final summary shows every round plus Average, Best, Worst, Standard Deviation, and Range.
Five 1-second rounds produce:
6.00 CPS, 7.00 CPS, 8.00 CPS, 7.00 CPS, 6.00 CPS
- Average CPS = 6.80
- Best CPS = 8.00
- Worst CPS = 6.00
- Range = 2.00

Limits, comfort, and privacy
- Measures
- Accepted physical Space presses, CPS, peak rate, intervals, consistency, half rates, Fatigue Change, per-second counts, and a one-second Best of 5 summary.
- Cannot verify
- Typing speed, WPM, reaction time, hardware condition, switch quality, ghosting, rollover, full latency, skill, macros, automation, or a medical condition.
- Local privacy
- Compact History and Personal Best stay in this browser. Raw events, timestamps, complete per-second arrays, held state, typed content, and identity are not saved.
Formal input requires a physical or connected keyboard event whose code is Space, with keydown followed by keyup. Repeat, other keys, editable targets, touch, pen, mouse input, and a virtual mobile keyboard do not count.
Use a natural, comfortable pace and stop if you feel pain or notable discomfort. ClickMetrik does not guarantee that high-speed repeated pressing is safe and does not provide medical diagnosis or treatment.
