(Possible Spoilers)
It was just revealed that the First Order Star Destroyers are actually a new class of star Destroyer and the Finalizer was the first of the class. It was also revealed that they are almost twice the length of a Imperial Class. With a Imperial Class being 1,600 meters and the resurgent class being 2,915.81 meters. So if FFG makes one for armada it should be around 14 to 15 inches, or around the same length of the CR90 in X Wing.
