Is an 8-foot door unheard of in WWII Germany? Just getting an eyeball on it, it seems that the doorways and windows are a bit over-sized, but it could just be me. There are door jamb and window jamb inserts provided that do shore up the openings about a 16th of an inch all the way around.

The door measures 2.75 inches, which converts out to a little over 8ft in 1/1. The door handle comes in around 3' 7", which seems a little high to me.
Anyway, what do you think? Too large a door? I'm not trying to nit pick, simply trying to figure out if I'm going to have to do a little converting!
