Okay, so I was wondering on the average size for what would constitute a normal spaceship in a sci-fi setting, so decided to look it up. I looked up Star Trek's USS Enterprise ship measurements as I figured that to be as good a template as any to build upon. The size however of the final version turned out to be between 610-910 meters, depending on the design, of which there were several.
So really my question is, how big would a large warship normally be? I figure anything in the high kilometer range would be the equivalent of a planetoid, which is too big, requiring too much energy and resources to run it. Of course, maybe I am being too nitpicky and none of this really matters. My character Briia is part of one of several space fleets of spaceships for her people and I was trying to figure out an estimate on the size of their war crafts. Since I am in the U.S. and do not use the metric system, I am less familiar with it since we normally use the English system of measurement.
Comments appreciated here.
