The USS Enterprise (NCC-1701-C) was a 24th century Federation Ambassador-class starship operated by Starfleet. It was the fourth Federation starship to bear the name Enterprise. In 2344, Captain Rachel Garrett served as the ship's commanding officer.
Not as much effort was put into the design of the Enterprise-C as was the case for the "stars" of Star Trek such as the Enterprise-D or -E. Therefore, there is only rudimentary information about the ship's construction, such as the drawings of the outer hull. As a first step in calculating the size, I added decks to the original blueprint of the Enterprise-C.

According to this blueprint the ship has 37 decks.
- The premise for all my deck calculations: a deck is 2.5m + 0.5m for EPS cables, power cables, ... = 3m height for a deck.
- My calculations follow a purely mathematical approach. I do not compare bridge modules or disk heights with each other. I always pull in decks based on the rows of windows and then calculate a physically plausible room height.
Now I checked whether this also matches the external appearance of the Enterprise-C in terms of the windows and the shuttle bays. The number of 37 decks fits this assumption very well.
With a deck height of 3m, this results in a total length of 491.5m.
The official length of 524.25m is therefore a bit too large. This is mainly because the producers issued the instruction that the Enterprise-C should simply have a length between the Enterprise-D and the Excelsior.
This size chart also contains the wrong size of the Excelsior class. If you just consider that the Excelsior class has 32 decks, then it already appears too small on the size chart.
The size of the Oberth class was also determined somewhat arbitrarily.
