Just a little info, I did a screen cap of the ENterprise D from Jeff Russel's Starship Deminsions, then resized it to match the one in the pic at the top of the page. According to this site, Ent D is 643 meters long and it covers 65 graph squares per the site background. That means each square is about 10 meters. I used this to establish the general (not exact) deminsions of the carrier. They are as follows: Height - 270 meters or 67.5 decks (4meters per deck); Beam - 800 meters (nose to tail); Span - 720 meters (wingtip to wingtip). All in all not nearly as big as I'd hoped, but still rather impressive. It still gets dwarfed by a Romulan Warbird, damn. Little pic to help illustrate the size comparison. (yeah I know it's old)
