Why Are Keyboards Not in ABC Order?

Early mechanical typewriters had metal arms that swung up to strike a ribbon and print a letter. If you typed two nearby keys quickly, the arms could collide and get stuck. The QWERTY layout was designed to place commonly paired letters far apart on the keyboard to reduce how often this happened.

Christopher Latham Sholes, the inventor of the first commercial typewriter, developed the QWERTY layout around 1873. His typewriter was manufactured and sold by Remington, which helped spread the layout widely across offices and businesses.

The evidence is mixed. QWERTY does separate some common letter pairs, but it was probably not a perfectly scientific arrangement. It likely evolved through trial and error rather than a detailed study of English letter frequency.

By the time computers replaced typewriters, QWERTY was already deeply embedded. Millions of people had learned to type on it. Businesses relied on it. Teaching everyone a new layout would have been enormously disruptive, so the layout simply carried over.

Yes. The Dvorak layout was designed in the 1930s to be more efficient, putting the most common letters on the home row. Some studies suggest it reduces finger movement. However, most people never switch because relearning takes significant time and the practical benefits are modest for casual typists.
