Modern piano keyboards ordinarily have an octave span of 164â165 mm; resulting in the width of black keys averaging 13.7 mm and white keys about 23.5 mm wide at the base, disregarding space between keys. Several reduced-size standards have been proposed and marketed.
Hereâs a simple piano keyboard diagram (below this paragraph). The white keys are all labeled. If you look closely, you will realize that the same note names are being repeated over and over. These notes are A, B, C, D, E, F and G. Whether itâs a 49, 61, 76 or 88 key keyboard, this is the note pattern of a piano.
