Why should pay attention to the Swage size?

Take metal door as an example,if the hinge swage size is too small,when the door is closed,the gap between door panel and door jamb will be too big which does not meet for security and fire rated requirement.

If the hinge swage size is too big,the door panel is like moving horizontally，which cause door panel may hit the jamb or the other panel and cannot close properly.
