John Martellaro at MacObserver got his protractor out and used those drawings that the City of Cupertino
Given that comforting sanity check, I measured the diameter of the Apple spaceship as 1615 ft, plus or minus a few ft., depending on where one places the ruler. That’s a radius of 807.5 ft.
The outside measurement on the plans is 760′ but the large outside shader structures could account for the additional size.
Interestingly, that is a bigger footprint than the world’s largest office building, the Pentagon, which at five stories tall, two basement levels and with a smaller courtyard, still has significantly more usable square footage.

Update: Obama Pacman notes that Apple could install 3 full sized Football fields in the courtyard (below).
