The nineteenth century

Before the 1880s, piano keyboards were generally smaller than today. Different sizes were available. There were pianos specifically marketed as being suited to women.
However, in the late 1800s, there was a push by piano manufacturers to increase piano sales by building large concert halls to attract audiences. The manufacturers hosted performances by well-known European virtuosos of the day, such as Franz Liszt. These halls required larger, more powerful instruments.

The keyboard configuration designed for the late nineteenth century male virtuosos, with no consideration given to the needs of the rest of the population, is what we have today.

Josef Hofmann

Josef Hofmann, a famous virtuoso in the early 20th century, had Steinway make him a keyboard with slightly narrower keys. In fact, the octave width was just 0.5 cm less than normal. (For further information, go to

Expressed as a fraction, the keyboard width was 31/32 of the standard width, approximately half way between the DS6.0® (15/16) and today’s ‘standard’ keyboard with 6.5 inch octave.  While his hand span was not particularly small, it was undoubtedly smaller than many other famous male concert pianists at the time. But his hands were larger than the majority of adult women today! It is interesting that even HE wanted ‘larger hands’.

Steinbuhler keyboards

Fortunately, over the last decade or so, one small manufacturer in the US (Steinbuhler & Company) has recognised and promoted the need for narrower keys. In particular, this development takes advantage of the full sound of the modern piano while fitting them with keyboards that are ergonomically suited to smaller hands. This “retro-fitting” gives the pianist 88 narrower keys that make no difference to the sound of their instrument. Other manufacturers that will make a smaller keyboard on commission include Laukhuff and Kluge. (See: Manufacturers & technicians)

Thus, gradually, but far too slowly, pianists are getting a choice. We don’t expect women and children to wear men’s clothes or ride the same sized bicycle or ski on large skis. Nor, indeed, do we expect them to play exactly the same sized violin or cello. All of us have a choice of size for those things, so why do we not also have a choice of size for piano keyboards?
