I am trying to decide how big I want the spaceship in my story to be, and how many people would be onboard.
It's a warship, a capital ship, and my initial thought was "1 kilometre long, about 120 people", but then I started thinking like... is that both too big, and too few people?
I looked up what battleships and such used to have, and apparently it was thousands of people, but things don't necessarily have to be the same in space.
Let's say it's more like somewhere between 500 and 700 metres. Maybe 200 to 300 metres wide. It's a bit spacious, so it's not just everyone crammed together in as small of a space as possible. Decently wide corridors, comfortable enough quarters (maybe four people per room? except officers, of course), cafeteria, gym, rec rooms, medical section, engineering, workshop, hangar bay, etc. Assisted by various drones/robots/droids, and a ship AI, sci-fi style. How many people would you need for that?
