The QWERTY Keyboard Was Designed to Slow Typists Down

The familiar arrangement of letters on our keyboards is a direct legacy of the mechanical limitations of the first commercially successful typewriters. Invented by Christopher Latham Sholes, early models featured keys arranged alphabetically. However, the metal arms, or typebars, that swung up to strike the ribbon and paper would frequently collide (Review) and jam when a typist quickly struck adjacent keys. This was a significant flaw that hindered the practicality of the machine. Fast typists would find their rhythm constantly interrupted by the need to manually unstick the jammed typebars, effectively slowing down their overall speed and efficiency.

To solve this mechanical problem, Sholes, with the help of his business associate James Densmore, undertook a redesign. After studying the frequency of letter pairs in the English language, he rearranged the keyboard to place common combinations, like "th," on opposite sides of the keyboard or in positions that required alternating hands. This new layout, which would become known as QWERTY from the first six letters on the top row, was patented in 1878. The goal was less about deliberately slowing down the typist and more about engineering a workaround to a mechanical fault, thereby enabling a more continuous and ultimately faster typing experience by preventing constant interruptions.

The QWERTY layout was sold to E. Remington and Sons, a gunsmith company that began mass-producing the "Sholes & Glidden Type Writer." As these machines became the industry standard, so did their keyboard layout. Even after technological advancements in typewriters and the advent of computers eliminated the issue of jamming typebars, the QWERTY layout has persisted. Decades of ingrained muscle memory and the established infrastructure of training and manufacturing have made it the enduring standard, a fascinating relic of 19th-century mechanical problem-solving that remains at our fingertips today.
