Method for determining manpower needed to crew a starship based on size

In the setting I'm building up, there are starships ranging from several meters in length to 1.6 kilometers. I'm trying to devise a means to determine what sort of manpower each ship would likely need.

My current method is looking at naval vessels of similar roles to their fictional counterparts (anywhere from World War II to cutting edge modern ships) and scaling their crew by the difference in size of the two ships.

I was curious to hear of other methods for determining crew requirements and to see if the numbers from my method sounded plausible.

.

Example of my method:

• Fictional ship: Heavily armed battleship, with a focus on firepower, length of 600 meters.
• Comparable ship: Yamato-class battleship, length of 256 meters (crew 2400-2700)
• 256/600 = 2.34
• Fictional ship crew: 2.34 * 2500 = 5859 maximum crew
