The History and Science of Typing Speed

The average person types around 40 words per minute. A professional typist hits 80–100. The world record is 216 WPM, set by Stella Pajunas on an IBM electric typewriter in 1946. But what counts as a “word”? Why do we measure speed this way at all? And does typing faster actually make you more productive? The answers are rooted in over a century of mechanical engineering, cognitive science, and office culture.

How WPM is calculated

Words per minute sounds simple, but “word” doesn't mean what you think. The standard WPM formula uses a standardised word length of 5 characters (including spaces). This convention dates back to typewriting competitions in the early 1900s, when judges needed a fair way to compare typists working with different texts.

Gross WPM = (Total characters typed / 5) / Minutes

Net WPM   = Gross WPM - (Uncorrected errors / Minutes)

Example:
  You type 300 characters in 1 minute with 2 errors.
  Gross WPM = (300 / 5) / 1 = 60 WPM
  Net WPM   = 60 - (2 / 1)  = 58 WPM

The 5-character standard means that typing “I am a cat” (10 characters including spaces) counts as 2 “words,” even though it's four actual English words. Conversely, “extraordinary” (13 characters) counts as 2.6 words. This normalisation lets you fairly compare typing in different languages and contexts.

The QWERTY story

The QWERTY layout was designed by Christopher Latham Sholes for the Remington No. 1 typewriter in 1873. The popular myth says QWERTY was designed to slow typists down to prevent jamming. The reality is more nuanced.

Early typewriters had mechanical arms (typebars) that would physically collide if adjacent keys were pressed in rapid succession. Sholes arranged the keys so that commonly paired letters were separated on the keyboard — not to slow typists, but to reduce the chance of jams. The constraint was mechanical, not about speed.

Alternatives that never won

• Dvorak (1936) — Designed by August Dvorak to minimise finger travel. Vowels on the left home row, common consonants on the right. Studies show a 4–8% speed improvement for trained typists, but the advantage is too small to overcome the switching cost.
• Colemak (2006) — A modern compromise: changes only 17 keys from QWERTY. Easier to learn than Dvorak because most shortcut keys (Ctrl+C, Ctrl+V) stay in place.
• Workman (2010) — Optimised specifically for programming, placing common punctuation characters in easier-to-reach positions.

QWERTY persists because of path dependence — once billions of people learn a layout, the cost of switching exceeds the marginal speed gain. Every alternative layout faces the same chicken-and-egg problem: nobody switches because nobody else has switched.

Keyboard switch types and speed

The physical mechanism under each key affects both typing speed and comfort. Three technologies dominate:

Mechanical switches register a keypress at the actuation point — typically halfway through the key travel — so you don't need to bottom out. This is why mechanical keyboard users often report faster typing: the keys register before they reach the bottom, reducing the total finger travel distance by up to 50%.

Optical switches go further by replacing the physical metal contact with a light beam. When the stem drops far enough to break the beam, the keypress registers. No metal contact means no debounce delay (the 5–10ms pause mechanical switches need to avoid registering one press as two).

Touch typing: the method behind the speed

Touch typing means typing without looking at the keyboard, using all ten fingers with each assigned to specific keys. The home row position (fingers resting on ASDF and JKL;) was formalised by Frank Edward McGurrin in 1888, who famously won a typing contest against a four-finger “hunt and peck” typist.

Research consistently shows that touch typists average 50–80 WPM, while hunt-and-peck typists average 20–40 WPM. But the speed gap narrows with experience — a study at Aalto University (2018) found that some self-taught typists who used only 6 fingers reached speeds comparable to trained touch typists. The key variable wasn't the number of fingers but consistent finger-to-key mapping — using the same finger for the same key every time, regardless of which finger it is.

Does typing speed matter for productivity?

The intuitive answer is yes — type faster, produce more. But research paints a more nuanced picture:

• For transcription (data entry, dictation) — speed is directly proportional to output. Faster is strictly better.
• For creative writing — thinking speed, not typing speed, is the bottleneck. Most writers compose at 20–30 WPM regardless of their maximum typing speed.
• For programming — a 2019 JetBrains survey found that developers spend only 30–40% of their time actually typing code. The rest is reading, thinking, debugging, and navigating. Doubling your typing speed might improve your coding output by 15–20%.
• For communication (email, chat) — typing speed has a measurable impact. Slack and Teams have made rapid text communication a core job skill.

Typing speed is like running speed for a football player — it helps, but the game is won by reading the field, making decisions, and being in the right position. The fastest typist isn't the most productive developer any more than the fastest runner is the best quarterback.
