By the end of this article, you will gain a deeper understanding of why the keyboard is not in alphabetical order and appreciate the unique factors that shaped its design.
Historical Development of the QWERTY Keyboard Layout
The QWERTY keyboard layout has its roots in the early days of typewriters. The first commercially successful typewriter, invented by Christopher Latham Sholes in the 1860s, featured a keyboard layout similar to the QWERTY arrangement we are familiar with today.
Initially, typewriters had an alphabetical keyboard layout, but this design had its drawbacks. The mechanical keys were arranged in alphabetical order, making typing at high speeds problematic. The proximity of frequently used letters caused the typewriter’s metal arms to jam when typing quickly, leading to frustration and delays in writing.
To address this issue, Sholes, along with his associate Carlos Glidden, experimented with different keyboard layouts to mitigate the jamming problem. They eventually developed the QWERTY layout, named after the first six letters in the top row of the keyboard.
The QWERTY layout was specifically designed to separate commonly used letters and reduce the likelihood of jamming. The placement of letters was strategically chosen to ensure that typists could type quickly and accurately without frequent intermingling of the mechanical arms.
Sholes received a patent for the typewriter, including the QWERTY keyboard layout, in 1878, leading to its widespread adoption by typewriter manufacturers. The QWERTY layout became the de facto standard, and as typewriters evolved and transitioned into keyboards for computers, the QWERTY layout persisted.
Interestingly, the reasons for the QWERTY layout’s success are partly due to market forces. Once the QWERTY layout gained traction and typewriters became popular, training and familiarity with the QWERTY arrangement made it difficult for individuals and businesses to switch to alternative layouts. This created a network effect, where the standardization of the QWERTY layout perpetuated its dominance.
While the QWERTY layout was initially developed to address mechanical jamming issues, advancements in technology have rendered this concern largely obsolete. Yet, despite the availability of alternative keyboard layouts, the outdated QWERTY layout persists in modern keyboards due to the inertia of tradition and the challenges associated with widespread adoption of new layouts.
The Purpose of the QWERTY Keyboard Layout
The QWERTY keyboard layout, despite its non-alphabetical arrangement, serves several important purposes that have contributed to its longevity and widespread adoption.
One of the key purposes of the QWERTY layout is to enhance typing efficiency. While it may seem counterintuitive at first glance, the non-alphabetical arrangement of keys actually helps to distribute the workload across the typist’s fingers more evenly. Commonly used letters are positioned in easily accessible locations, requiring minimal finger movement. This layout promotes faster typing speeds and reduces fatigue, especially for touch typists who can type without looking at the keys.
The QWERTY layout also takes into account the frequency of letter combinations and words in the English language. By placing commonly occurring letter pairs, such as “th” and “st,” on different sides of the keyboard, there is a reduced chance of typists’ fingers colliding, further improving typing speed and accuracy.
Another purpose of the QWERTY layout is compatibility and familiarization. The widespread use of the QWERTY keyboard layout across different devices, software, and operating systems makes it easier for individuals to switch between devices without having to relearn a new keyboard layout. This compatibility has been a significant factor in maintaining the dominance of the QWERTY layout despite the availability of alternative layouts.
Furthermore, the QWERTY layout also considers the traditional order of letters on typewriter typebars. In older typewriters, the order of letters on the typebars, which struck the paper to produce ink imprints, was arranged in a similar fashion to the QWERTY layout. As a result, the QWERTY arrangement allowed typewriter manufacturers to adapt the existing mechanical components to accommodate the new layout, ensuring a smoother transition from the alphabetical layout.
While the QWERTY layout has its advantages, it is not without its drawbacks. The arrangement of keys can lead to inefficient finger movements, particularly for common letter combinations. This has sparked the development of alternative keyboard layouts, which we will explore in the next section.
In summary, the purpose of the QWERTY keyboard layout is to maximize typing efficiency, minimize finger collisions, ensure compatibility, facilitate familiarization, and leverage existing mechanical components. These factors have contributed to the continued prominence of the QWERTY layout in today’s keyboards.
The Efficiency Debate: QWERTY vs. Alternative Keyboard Layouts
The efficiency of the QWERTY keyboard layout has been a subject of debate for decades. Critics argue that the non-alphabetical arrangement of keys in the QWERTY layout leads to inefficient typing and increased risk of repetitive strain injuries. In response, various alternative keyboard layouts have been proposed and developed.
One prominent alternative layout is the Dvorak Simplified Keyboard (DSK), invented by Dr. August Dvorak and his brother-in-law, Dr. William Dealey, in the 1930s. The Dvorak layout aims to optimize typing efficiency by placing the most commonly used keys on the home row, where the typist’s fingers naturally rest. This arrangement minimizes finger movement and strain, increasing typing speed and reducing the potential for repetitive stress injuries. However, despite its potential benefits, the Dvorak layout has struggled to gain widespread adoption, primarily due to the established dominance of the QWERTY layout.
Another alternative layout that has gained some traction is the Colemak layout. Designed by Shai Coleman in 2006, the Colemak layout seeks to strike a balance between typing efficiency and ease of transition from the QWERTY layout. It rearranges a few key positions from the QWERTY layout while keeping most of the keys in their original positions. This layout aims to improve typing speed and reduce finger movement without requiring users to relearn the keyboard layout from scratch.
Proponents of alternative layouts argue that they offer tangible advantages over the QWERTY layout. Studies have shown that alternative layouts can indeed improve typing speed and reduce errors when users reach a higher level of proficiency. However, the benefits of alternative layouts may vary depending on individual typing styles, preferences, and the amount of time invested in learning and adaptability.
Despite the logical appeal of alternative layouts, the QWERTY layout has remained dominant due to several reasons. First, the QWERTY layout has become deeply ingrained in the muscle memory and typing habits of millions of users worldwide.

The Dvorak Simplified Keyboard (DSK) is an alternative keyboard layout designed to optimize typing efficiency and reduce finger movement and strain. It was invented by Dr. August Dvorak and his brother-in-law, Dr. William Dealey, in the 1930s. The Dvorak layout seeks to improve upon the limitations of the QWERTY layout by placing commonly used keys on the home row, where the typist’s fingers naturally rest.
The Dvorak layout is based on several principles. One key principle is the distribution of letters to minimize finger movement. Commonly used keys, including vowels and the most frequent consonants, are positioned on the home row, allowing for efficient typing without the need for finger stretching or reaching. Letters that tend to appear consecutively, such as “th” and “st,” are placed on opposite hands, further reducing hand and finger strain.
In contrast to the QWERTY layout, the Dvorak layout aims to prioritize the use of the stronger and more dexterous fingers. The strongest fingers (the index and middle fingers) are responsible for the majority of keystrokes, while the weaker fingers (such as the pinky) are assigned fewer and less commonly used keys. This design reduces the risk of overworking the weaker fingers and helps maintain a more natural and comfortable typing rhythm.
Research has shown that the Dvorak layout can lead to increased typing speed and improved accuracy for proficient users. The optimized placement of frequently used keys on the home row reduces finger movement and the need to shift hands, resulting in smoother and faster typing. Additionally, the layout’s emphasis on alternating hands and utilizing stronger fingers contributes to reduced fatigue and potential for repetitive strain injuries.
Despite its potential benefits, the Dvorak layout has faced challenges in achieving widespread adoption. One obstacle is the established dominance of the QWERTY layout that has become deeply ingrained in the muscle memory and typing habits of users worldwide. The inertia and the cost associated with transitioning to a completely different layout have hindered the Dvorak layout’s popularity.
Furthermore, the availability of the Dvorak layout on standard keyboards and devices can be limited, making it less accessible compared to the QWERTY layout. While software-based solutions and custom keyboards exist, the widespread compatibility of the QWERTY layout across devices and operating systems makes it more convenient for users.

It was designed to strike a balance between typing efficiency and ease of transition from the QWERTY layout. The Colemak layout aims to improve typing speed and reduce finger movement while maintaining a level of familiarity for users.
The Colemak layout retains most of the QWERTY layout’s letter positions, making it easier for users to adapt to the new layout. However, it makes a few key rearrangements to optimize efficiency. One notable change is the swapping of the positions of the “A” and “N” keys, which places the most commonly used consonant, “N,” on the home row, and the less frequently used “A” in a less prominent position.
An important principle in the Colemak layout is to keep the frequently used keys on the home row while minimizing finger movement. The layout focuses on utilizing the stronger and more dexterous fingers for commonly used keys, reducing strain on the weaker fingers. Additionally, letter combinations such as “TH” and “ST” are positioned on different hands to promote efficient and comfortable typing.
Due to its similarities to the QWERTY layout, the learning curve for transitioning to Colemak is relatively gentle. Users with a strong foundation in touch typing can adapt to the layout with practice and minimal adjustments. This ease of transition has contributed to the popularity of the Colemak layout among those seeking an alternative to QWERTY.
The Colemak layout has gained recognition for its potential benefits in terms of improved typing speed and reduced finger movement.
