Tonkan,

I did some measuring and some research.
Yamaha Pianos (acoustic and digital including all 88 note weighted actions) are 165mm to the octave.
Yamaha Organs (antique and comtemporary) are 160mm to the octave.
Yamaha Synthesizer, portable keyboards etc are all 160mm to the octave.
The Tyros keyboard is 160mm to the octave.
The PSR2000 keyboard is 160mm to the octave.
The DX7 keyboard is 160mm to the octave.
This is full size! If some other manufacturer wants to make their keys bigger, that's fine.

Regards,
