The Typewriter That Defined QWERTY - A 150-Year History of Keyboards and Typing Speed

On whatever device you are reading this article, the top-left row of the keyboard almost certainly reads "QWERTY." This layout was designed in 1873 and has remained the world standard for over 150 years. Even smartphone software keyboards follow it. Why has a layout born from the mechanical constraints of the 19th century survived into the touchscreen era? Tracing the history of text input through the lens of "how many characters can you type per minute" reveals a fascinating story woven from technology and human habit.

Sholes's Typewriter and the Birth of QWERTY

In 1868, American newspaper editor Christopher Latham Sholes, along with Carlos Glidden and others, patented a typewriter. The early prototype had a piano-like two-row key layout with the alphabet in order. But this arrangement had a fatal flaw.

Typewriters of the era used an "upstrike" mechanism in which type bars swung upward to strike the paper from below. When adjacent keys were pressed in rapid succession, the next type bar would rise before the previous one had returned, causing the bars to jam. To avoid this mechanical jamming, Sholes sought a layout that physically separated letter pairs frequently typed in sequence.

In 1873, the Remington arms company commercialized Sholes's typewriter, selling it as the "Sholes & Glidden Type-Writer." The layout it shipped with was the prototype of today's QWERTY. The price was $125 - extremely expensive considering the average annual income at the time was about $500.

The "Designed to Slow You Down" Myth - Fact or Fiction?

A widely circulated claim about QWERTY is that it was "deliberately designed to slow down typing." However, this theory does not withstand historical scrutiny.

Research by Professor Koichi Yasuoka of Kyoto University and others suggests that telegraph operators had a major influence on the QWERTY layout. One of the typewriter's primary uses at the time was recording incoming telegraph messages. For operators transcribing Morse code, it was important that certain letter combinations (for example, letters likely to follow "Z") be in easy-to-reach positions.

In other words, QWERTY was not designed "to be slow" but was a compromise "to keep the machine from breaking while maintaining practical speed."

The Dvorak Layout - A Scientifically Designed Rival

In 1936, Professor August Dvorak of the University of Washington patented a new key layout based on a scientific analysis of English letter frequency and finger movement. The Dvorak Simplified Keyboard was designed on the following principles.

The most frequently used letters are concentrated on the home row (middle row). About 70% of English text can be typed using only home-row keys. For QWERTY, this figure is only about 32%. Letters are also arranged so that the left and right hands alternate keystrokes, preventing one hand from bearing a disproportionate load.

In theory, Dvorak is overwhelmingly more efficient, yet the actual difference in typing speed is surprisingly small, as numerous experiments have shown. A 1956 study by the U.S. General Services Administration (GSA) found no significant productivity improvement when QWERTY typists were retrained on Dvorak. Human fingers have a physical speed ceiling, and layout efficiency differences become negligible near that ceiling.

Japanese Input Efficiency - Romaji vs. Kana

Japanese text input faces a "character efficiency" problem entirely different from that of English-speaking countries. As the difference between full-width and half-width characters illustrates, each Japanese character carries more information than an English letter. There are two main methods for typing Japanese on a keyboard: romaji input and kana input.

Romaji input requires an average of 1.7 keystrokes per Japanese character. Contracted sounds like "kyo" need 3 keystrokes, and the double consonant "っ" is expressed by repeating the consonant. Kana input, on the other hand, generally requires just 1 keystroke per character, though voiced and semi-voiced marks need extra keystrokes, and the larger number of keys increases finger travel distance.

In terms of theoretical maximum input speed, kana input surpasses romaji. In practice, however, romaji input users are the overwhelming majority (an estimated 85% or more). The decisive advantages are that it reuses the English key layout and requires memorizing fewer keys. Given the complexity of Japanese writing rules, the choice of input method cannot be decided by speed alone.

The Flick Input Revolution - Text Input in the Smartphone Era

In 2008, "flick input" was introduced for Japanese input on the iPhone. Based on the mobile phone's ten-key layout (10 keys for the Japanese syllabary rows a through wa), flicking a key up, down, left, or right reduced the old toggle input (pressing the "a" key 5 times to type "o") to a single gesture.

Skilled flick input users can type 120-150 Japanese characters per minute. This rivals or even exceeds the speed of romaji input on a physical keyboard (about 100-120 characters/min for experienced typists). The ability to operate with one hand and type while looking at the screen are also major advantages.

Voice Input - Character Efficiency Beyond the Keyboard

Voice input has brought the most dramatic speed improvement in the history of text input. The natural speaking rate for Japanese is about 300-400 characters (morae) per minute. With today's improved speech recognition accuracy, practical input speeds reach 200-300 characters per minute.

In English, the average speaking rate is about 150 words per minute (WPM). At an average of 5 characters per word, that is roughly 750 characters per minute. The Guinness-recognized typing speed record is 300 WPM, set by Anthony Ermolin on TypeRacer in 2023 (a 15-second sprint). For sustained typing, Barbara Blackburn's 212 WPM on a Dvorak keyboard in 1985 was long considered the benchmark.

Voice input, however, has constraints that keyboard input does not: ambient noise, privacy concerns, the cumbersome nature of dictating punctuation and line breaks, and the fact that it is poorly suited to "thinking while writing." Editing tasks like those described in techniques for reducing text length are difficult with voice input alone.

Thumb Shift (NICOLA) - A Japanese Optimization

In 1979, Fujitsu introduced the "Thumb Shift Keyboard" (NICOLA layout). Two "thumb shift keys" were placed where the space bar normally sits, and pressing a character key simultaneously with a thumb shift key directly produced voiced or semi-voiced characters.

With JIS kana input, typing "ga" requires two keystrokes ("ka" + voiced mark), but with Thumb Shift it takes just one. Since voiced and semi-voiced characters account for about 20% of Japanese text, this difference accumulates into a significant efficiency gain. The layout was famously used by author Kazuyo Katsuma and many professional writers.

In 2020, however, Fujitsu announced the discontinuation of Thumb Shift keyboards, citing declining demand for the dedicated hardware. An input method supported by passionate users for over 40 years could not overcome the "law of inertia" any more than QWERTY could be displaced. Some users still emulate Thumb Shift via software, but their numbers are shrinking year by year.

Predictive Conversion and Input Efficiency

Apart from physical keystroke speed, predictive text technology has dramatically improved "effective input character count." On smartphone Japanese input, typing just a few characters brings up candidates, and a single tap can confirm a long word or phrase.

For example, typing the 9-character phrase "otsukaresama desu" (お疲れ様です) in full via flick input takes 9 keystrokes, but with predictive conversion, "otsu" (2 keystrokes) + candidate selection (1 tap) completes it in 3 operations - effectively tripling input efficiency.

Google Japanese Input and Apple's Japanese predictive engine combine user input history with large-scale language models to generate candidates. The more you use a phrase, the fewer keystrokes it takes, so individual input efficiency improves over time. This "learning input system" broke through the speed barrier via an approach entirely different from key layout optimization.

Stenotype - Text Input in the World of Shorthand

The stenotype (shorthand typewriter) used in court reporting and real-time captioning achieves astonishing input speeds through an approach completely different from a standard keyboard. A stenotype uses "chord input" - pressing multiple keys simultaneously from a set of 22 - to enter an entire syllable or word in a single stroke.

Skilled court reporters type at 225 WPM or more, comfortably exceeding normal speaking speed (about 150-180 WPM). The National Court Reporters Association certification exam requires 225 WPM for 5 minutes at 95% accuracy or better. Top-level reporters can exceed 300 WPM.

Keyboard Layouts Around the World - QWERTY Is Not Universal

QWERTY is called the world standard, but France uses AZERTY and Germany uses QWERTZ - different layouts. These are based on QWERTY with key positions swapped for letters frequently used in each language.

In 2019, the French government established an improved version of the AZERTY layout as a national standard (NF Z71-300). The traditional AZERTY made it cumbersome to type French accented characters (e, e, e, e, etc.), so keys providing direct access to these characters were added. The nationalization of a keyboard layout is a symbolic event demonstrating that text input is part of a country's cultural infrastructure.

150 Years of Typing Speed - A Numerical Retrospective

From the typewriter of 1873 to voice input in the 2020s, text input speed has improved dramatically over about 150 years. What is fascinating, however, is that keyboard input speed itself had already reached roughly today's level by the 1920s.

Typing contests in the 1920s already produced records exceeding 100 WPM. In other words, keyboard input speed has barely changed in about 100 years. What has changed is the diversification of input devices (flick input, voice input) and improvements in conversion and prediction accuracy that boost effective input efficiency.

The history of text input is also a history of shifting bottlenecks - from "mechanical constraints" to "physical limits of the human body" to "cognitive limits." In the typewriter era, keeping the machine from breaking was the top priority. In the electronic keyboard era, the physical speed of fingers was the ceiling. And in the voice input era, the speed at which a person can think about "what to write" has become the ultimate bottleneck.

The primary reason QWERTY has survived for 150 years is not the layout's efficiency but the inertia of muscle memory acquired by billions of people. No matter how superior a new layout may be, the cost of having the world's typists switch all at once is astronomical. The future of text input may lie not in optimizing key layouts but in input methods that transcend the keyboard altogether - voice, gesture, and eventually brain-computer interfaces.
