piano sizes?

Ernest Burden · August 24th, 2003

This may have been covered before, but I have never found an adequate answer, the question of how big a piano is.

First of all, not all pianos of a 'class' are the same size, so there isn't ONE correct answer. I have found various CAD symbols and some 3D models, but they vary enough that I cannot tell who's right, and their keyboards are often layed out wrong. I have some plan photos that are my best hope...

So all I really want to know is this: How wide is an octave, CL to CL, on a grand piano? I
have counted that on grands (from photos, I don't have one handy) there are 7 full octaves (Bflat to Bflat) plus one key at the bass end and two keys at the other--starting at low A and ending at high C. If I know the width of a standard octave I can size any image and build my model over it.

Or if anyone can point me to a detailed, accurate plan, I would appreciate it.

Thanks in advance

Maybe either of these will help?

Maybe not quite what you are looking for, but doesn't hurt to try.

width of an octave is exactly 16 cm.
