The keyboard is an essential component of modern computing, allowing users to interact with their devices and create content with ease. However, the keyboard layout we use today is not the original design. In fact, the first keyboard layouts were designed to slow down the typist’s fingers to prevent keys from jamming together. In this article, we will delve into the history of the keyboard layout, exploring its origins, evolution, and the factors that influenced its design.
Introduction to the Early Typewriters
The first typewriters were invented in the 1860s, with Christopher Sholes, a newspaper editor and printer, developing the first practical typewriter in 1868. Sholes’ early typewriter, called the “Type-Writer,” had a keyboard layout that was designed to accommodate the mechanical limitations of the device. The keys were arranged in a way that would prevent the metal arms or “typebars” that struck the ink onto the paper from colliding and jamming together.
The Sholes and Glidden Type-Writer
The Sholes and Glidden Type-Writer, which was the first commercially produced typewriter, had a keyboard layout that was quite different from the one we use today. The layout was designed to slow down the typist’s fingers, with common letter combinations placed far apart from each other. This was done to prevent the typebars from jamming together, which would cause the machine to malfunction.
Mechanical Limitations
The mechanical limitations of the early typewriters played a significant role in the design of the keyboard layout. The typebars were arranged in a circular pattern, with each key striking the ink onto the paper in a specific location. When a key was pressed, the corresponding typebar would swing up to strike the ink onto the paper. If two keys were pressed in rapid succession, the typebars could collide, causing the machine to jam. To prevent this, the keyboard layout was designed to slow down the typist’s fingers, with common letter combinations placed far apart from each other.
The QWERTY Layout
In 1874, Sholes and his collaborators, Carlos Glidden and Samuel W. Soule, developed a new keyboard layout that would become the standard for modern typewriters. The QWERTY layout, named after the first six keys in the top left letter row, was designed to reduce the likelihood of typebar collisions. The layout placed common letter combinations far apart from each other, with the most common letters and digraphs (combinations of two letters that appear together frequently in words) placed on opposite sides of the keyboard.
Design Principles
The QWERTY layout was designed based on several principles, including:
The placement of common letter combinations far apart from each other to prevent typebar collisions
The placement of the most common letters and digraphs on the home row (the middle row of keys) to reduce finger movement
The placement of the least common letters on the top and bottom rows to reduce finger movement
Adoption and Standardization
The QWERTY layout quickly became the standard for modern typewriters, with most manufacturers adopting the design. The layout was also adopted by early computer manufacturers, who used it as the basis for their keyboard designs. Today, the QWERTY layout remains the most widely used keyboard layout, with over 90% of keyboards using this design.
Alternative Keyboard Layouts
While the QWERTY layout remains the most widely used keyboard layout, there are several alternative layouts that have been developed over the years. These include the Dvorak Simplified Keyboard, the Colemak layout, and the AZERTY layout, among others. Each of these layouts has its own unique design principles and advantages, with some designed to reduce finger movement and others designed to improve typing speed and accuracy.
The Dvorak Simplified Keyboard
The Dvorak Simplified Keyboard, developed in the 1930s by August Dvorak and William Dealey, is a keyboard layout designed to be more efficient and ergonomic than the QWERTY layout. The layout places the most common letters and digraphs in the English language on the home row, with the least common letters on the top and bottom rows. The layout also places common letter combinations together, rather than far apart, to reduce finger movement.
Comparison to QWERTY
The Dvorak Simplified Keyboard has several advantages over the QWERTY layout, including reduced finger movement and improved typing speed and accuracy. However, the layout has not gained widespread adoption, due in part to the difficulty of switching from the QWERTY layout and the lack of support from keyboard manufacturers.
Conclusion
The original keyboard layout, designed to accommodate the mechanical limitations of early typewriters, has evolved over the years to become the QWERTY layout we use today. While alternative keyboard layouts, such as the Dvorak Simplified Keyboard, have been developed to improve typing efficiency and ergonomics, the QWERTY layout remains the most widely used keyboard layout. Understanding the history and design principles of the keyboard layout can help us appreciate the complexity and nuance of this essential component of modern computing. By exploring the evolution of the keyboard layout, we can gain a deeper understanding of the factors that have shaped the design of modern keyboards and the ways in which they can be improved to meet the needs of users.
In terms of key takeaways, it is clear that the keyboard layout has a rich and fascinating history, with the QWERTY layout emerging as the standard due to its ability to reduce typebar collisions and improve typing efficiency. The design principles of the QWERTY layout, including the placement of common letter combinations far apart from each other and the placement of the most common letters on the home row, have had a lasting impact on the development of modern keyboards. As we look to the future of keyboard design, it is essential to consider the ways in which the layout can be improved to meet the needs of users, whether through the adoption of alternative layouts or the development of new designs that prioritize ergonomics and efficiency.

What is the original keyboard layout and how was it designed?
The original keyboard layout, also known as the QWERTY layout, was designed in the 1870s by Christopher Sholes, a newspaper editor and printer. Sholes developed the first practical typewriter, and the QWERTY layout was intended to solve the problem of keys jamming together when pressed in rapid succession. The layout was designed to slow down the typist’s fingers to prevent keys from colliding and jamming, by placing common letter combinations farthest from each other on the keyboard.
The QWERTY layout was not designed with efficiency or ergonomics in mind, but rather as a solution to the mechanical limitations of early typewriters. Despite its inefficiencies, the QWERTY layout became the standard for typewriters and has remained so for computer keyboards. The layout has undergone some modifications over the years, but its basic design has remained the same. Today, the QWERTY layout is still widely used, although alternative layouts such as the Dvorak Simplified Keyboard have been designed to be more efficient and ergonomic.
How did the QWERTY layout become the standard keyboard layout?
The QWERTY layout became the standard keyboard layout due to a combination of historical and practical factors. When the first typewriters were introduced, the QWERTY layout was the only game in town, and it became the de facto standard. As more typewriters were manufactured and sold, the QWERTY layout became the norm, and manufacturers had little incentive to change it. Additionally, the QWERTY layout was reinforced by the widespread use of typewriters in schools and businesses, where it was taught as the standard keyboard layout.
The QWERTY layout’s dominance was further cemented by the advent of personal computers in the 1970s and 1980s. Computer manufacturers adopted the QWERTY layout as the standard keyboard layout, and it has remained so to this day. While alternative keyboard layouts have been proposed and implemented, the QWERTY layout remains the most widely used and accepted layout.
