Ok Bruce, you've aroused my curiosity. Here's measurements on keyboards
around my place ---
C to C inclusive measured over 5 octaves:
Yahama AN1x - 32 1/2"
Korg 01/W Pro - 32 1/2"
Ensoniq KT-76 - 33 7/16"
Mehlin & Sons Upright Grand (about 100 years old, real ivory keys) - 33 1/4"
General Music CD10 (home type keyboard with speakers) - 33 5/16"
Sorry for the English measurements (for the rest of the logical Metric
world) but I didn't have a tape that has both systems.
So, it seems you have questioned a standard which is not a standard. Notice
how the Japanese companies have the narrower width. (General Music is based
in Italy although that particular board could have been made anywhere.)
Would anyone else like to contribute measurements? How about a history of
how the width of piano keys came about?
