Good morning..

So Donny if you have a straight, short, flat metal or wood ruler it would be simple to measure an octave span on the Pa800. Place one end of the ruler at the lower end of, for example, the middle C key and measure it up to the outer edge of the B key and if it measures 6.5 inches then it would be considered an 165mm octave span keybed and therefore would indeed have the larger conventional standardized key width size. Larger than Yammies 160mm octave span that they have on their arrangers and synth action workstations in other words. And what I consider to be 'true' full size keys if indeed the Korg has an 165mm octave span keybed.

Best,
Mike
