I have several different WIP Enterprise sizes; for a 947' ship I use the 3/4 ratio rule on the hangar model, so the hangar's new dimensions are 122'x3/4 = 91.5' length, etc. The hangar door size fits fairly nice at this scale. I always insert a 24' shuttlecraft per Kirk's dialog in
The Galileo Seven. (Note my curved corridors.

For a ship to fit the 122' length hangar model and also fitting it to the hangar doors again, I found a up-scaled ship size using the 4/3 ratio rule which is 947'x4/3 =1263' which works quite well. YMMV
