I want to find out the general size of the ships in the Imperial Navy, but I can't find any proper figures anywhere. Do canon figures exist? Forums, fanfics and other such sources range the largest of them from anywhere around 10km to 25km. Does anyone know?

2947072 I recall, though I could be wrong, one of the Primarchs having a flagship nearly 60 kilometers long.

Hope this helps. Larger ships exist, but none over 50km or so, and even they are one-offs. The largest produced pattern is something like 30km.

You can find some approximations and size charts, just Google it.

rouge trader has some ship stats.
