Mechanical Keyboard CPS Test
One real passage reveals your typing speed, accuracy and key feel — and puts two keyboards on the same ruler.

概要
Most CPS tests measure one thing: how fast you can mash a single key. This one measures how you actually type. You type a real passage — with spaces, punctuation, capitals and movement between keys — at your normal speed. Because the input is identical every run, your results are comparable across sessions and across mechanical keyboards; because the text is real, the number reflects real use. Read three things: speed (CPS / KPS), accuracy, and how the mechanical keyboard feels.
使用方法
- Pick a test duration — 10 seconds is easiest to repeat; keep it fixed, because baseline comparisons only work at the same duration.
- Choose the keyboard layout you are testing (65%, esports, numpad or full size). This only changes the keyboard drawn on screen, not the physical board under your hands.
- Press Start, then type the passage at your normal speed — it loops automatically.
- Watch the second-by-second bars (your rhythm) and the accuracy figure next to them: fast but inaccurate is not efficient.
- Type the same passage on a second mechanical keyboard, export both result cards and compare them side by side.
- After changing a mechanical keyboard setting (debounce level, wired vs wireless), retest. Run each board two or three times and compare your best run.
機能詳細
Why this number is more trustworthy than mashing
Other CPS tests ask you to hammer one key, which measures your single-key limit — nothing to do with how you actually type. Here you type a real passage: spaces, punctuation, capitals, movement between keys. The same motions you use writing mail, chatting or coding. Because the input is identical every run, two sessions and two mechanical keyboards are directly comparable; because the text is real, it is closer to real use.
Three dimensions, not one number
· Speed (CPS / KPS): how many key presses per second you manage to register.
· Accuracy: how many of the characters you typed were correct (correct characters ÷ characters typed, including mistakes you retyped). High speed with a pile of errors is not high output — and mashing cannot show you this at all.
· Feel: read it in two places. First, the second-by-second bars are your typing rhythm — a steady row means you are flowing, spikes and dips mean you are rushing, hesitating or getting blocked. Second, type the same passage on both mechanical keyboards: which one tires your fingers first? Rhythm and fatigue together are the mechanical keyboard's feel.
(Stamina is a bonus: run 30 seconds, then 60. If the second half collapses, that is fatigue, not a fast mechanical keyboard.)
After switching mechanical keyboards: does it suit you? (compare with your daily average)
· CPS within ±5% and accuracy down ≤1%: effectively the same feel — it works straight away, no adaptation needed.
· CPS off by 6–15% and accuracy down 2–5%: a clear difference. Give it a few days before deciding.
· CPS off by more than 15% and accuracy down more than 5%: too far from the feel you are used to — do not switch to it for daily work right away.
· Drift means adaptation cost, not quality: faster with steady accuracy usually suits your hands better, while slower speed or falling accuracy is the warning sign. If runs are wildly inconsistent, repeat first — a single jump is more likely your own warm-up than the hardware.
These bands are rules of thumb, not statistically significant thresholds.
For the technically curious
Debounce delay, polling rate, scan rate, key travel and actuation force all influence how a board responds. This page measures none of them — it shows you the outcome instead of the signal. For millisecond-level numbers, use a dedicated latency test; to find out whether fast fingers actually get through, stay here.
What this test is not
It measures speed, accuracy and rhythm on real text, but it is not a full typing assessment — no long-form WPM score, no error-correction or proofreading strategy score, no vocabulary or grammar dimension. It also cannot tell you your key travel in millimetres, your debounce setting in milliseconds or your input lag. It is a comparison ruler, not an instrument. Run each mechanical keyboard two or three times and compare your best run, because a single run naturally varies by around 10% either way.
ベンチマーク
Build your own baseline first. Before switching mechanical keyboards, run two or three tests on the board you are most used to and keep your best run — that is your daily average. Every time you change keyboards or settings, retest under the same passage, same duration and same physical placement, then compare against that number. The table below measures how far you drift from your own baseline, not how you compare with a global average.
| Verdict | CPS (vs your daily average) | Accuracy (vs your daily average) |
|---|---|---|
| Suitable | Within ±5% | Down ≤1%, or equal / better |
| Needs time to adapt | Off by 6–15% | Down 2–5% |
| Not suitable | Off by more than 15% | Down more than 5% |

よくある質問
Is this just a key speed test? Can I score high by mashing?
No. Mashing one key really fast does produce a big CPS number, but that is your single-key limit and has nothing to do with your normal typing. Here you type a real passage at your usual speed — with spaces, punctuation, capitals and movement between keys — and accuracy is recorded at the same time: high speed with a pile of typos is not high output. So what we record is how your current keyboard performs under real input: speed, accuracy and comfort. When you buy a new keyboard, or after this one has seen a lot of use, compare the two data sets and the real change shows up.
What does CPS mean in a keyboard test?
CPS stands for clicks per second, borrowed from mouse testing. On a keyboard it means key presses per second. Many people say KPS (keys per second) instead — it is the same measurement, and the number on this page is both.
What is a good CPS score?
There is no single answer — the same person can swing by around 10% between boards, or even between days. That is why the table below is not a global average but a comparison against your own baseline: run two or three tests on the keyboard you are most used to, keep your best run as your daily average, then retest after switching and look at the drift. If you only want a rough community reference: on a 10-second test, relaxed single-key tapping lands around 6–7 per second — but that measures one key, not your performance on real text.
Is this a typing speed test? How is it different from a WPM test?
Partly. It measures your key speed, accuracy and rhythm on real text, but it is not a full typing assessment: no long-form WPM score, no error-correction or proofreading strategy score, no vocabulary or grammar dimension. Think of it as your raw input performance on your current keyboard, not a typing certificate.
What affects my CPS?
Three main things. 1) The keyboard: different switches have different pre-travel, actuation force and return speed, which changes both your speed and the feel. 2) Keyboard condition: ageing, dust and oxidised contacts make keys sluggish or double-fire, so the number drops or becomes erratic. 3) Keyboard settings: mechanical boards often expose a debounce level that filters contact bounce — set too high it swallows fast repeated presses, set too low you get duplicate input, and both distort your reading. Run a test when a new keyboard arrives, compare it against your old one, then keep it as your baseline.
Why did my CPS jump a lot after switching to a mechanical keyboard?
Most mechanical keyboards trigger faster — shorter pre-travel, snappier return — so your reading on the same passage goes up, and that is usually genuinely better response. But rule out one false rise: if the debounce level is set very low, a slow or half press can let contact bounce register as two inputs, counting one press twice and inflating the number. The check takes seconds: type a line at your normal speed in any text field and look for duplicated characters. If there are duplicates, that is key chatter, not a faster board — raise the debounce level.
Why is my CPS different on a 65% keyboard than on a full-size one?
If these are two different physical keyboards, the difference can come from the hardware (switches, pre-travel, layout) and also from placement: a 65% board is shorter, so a full-size keyboard usually gets pushed to the right to make room for the mouse, which quietly changes your wrist angle and where your left hand lands. Comfort shifts and takes time to adapt to. Test each keyboard where you actually use it, and keep the position fixed before comparing. One note: the layout switch in this page only changes the keyboard drawn on screen to help you follow the key positions — it does not change the board under your hands. To compare two keyboards, test the two physical boards separately.
Why is my score lower on letter keys than on the spacebar?
The spacebar is wide and forgiving, and you can hit it with your thumb or either hand. Smaller keys need more aim, and aiming costs time. The same effect explains why your score changes between keyboards.
Can you measure my debounce delay or input lag?
No — and be careful with pages that claim to. Debounce delay, polling rate, scan rate and input lag are millisecond-level hardware properties that need dedicated instrumentation. This page shows you the outcome instead: if fast fingers do not get through, something along the chain is eating input.
Can you tell me my key travel in millimetres?
No. Travel, actuation point and actuation force must be measured on the hardware itself. What this test can do is show you, from your own numbers, which of two keyboards is friendlier to your hands.
Why does my score change so much between runs?
Because you do. Warm-up, fatigue and attention move a single run by around 10%. Run each keyboard two or three times and compare your best run rather than a single attempt.
If my score jumps, does that mean my keyboard is faulty?
Not necessarily. A steady rise on a second keyboard usually means it suits your hands better. But a sudden, unstable jump is worth a 30-second sanity check: type in any text field and look for duplicated characters, which points to key chatter rather than a faster board.
I only have one keyboard — is this still useful?
Yes. You get a personal baseline: retest after changing debounce level, switching from wireless to wired, or breaking in new switches, and see whether the number moved. Regular retests also reveal ageing.
What is the fastest CPS ever recorded?
Competitive players using jitter or butterfly techniques reach roughly 15–20 CPS, far above the 6–7 casual average. That is a technique limit, not a keyboard limit.
Is this the same as a button mashing test?
Essentially, yes. Button mashing, tap speed and CPS all describe how fast you can press; the difference here is that you get an exact number, on a fixed passage and with accuracy recorded, that you can compare across keyboards.
Why do I have to type the same passage every time?
Because that is what makes the comparison valid. Mashing randomly changes the input every run, so two results are not comparable. A fixed passage removes that variable — which is also why the result cards are worth keeping.
Do osu! or StarCraft players use this?
Yes. In rhythm and RTS communities the same measurement is called a KPS test (keys per second), used to benchmark stream speed, singletapping and double tapping. The number here is the same one.
