Typically an overhead door is the same size as the rough opening. Adding the jambs and the weather strips provide the overlap. You can get a 14' x 8' steel door that is not a special order door, will be the same price as a 16' x 8'. The door will overlap the opening 3" on each side, which isn't a big deal. I'm a door installer in Ohio. In my area, a door like that which would be 2" thick, fully insulated, steel front and back, would be $1250 installed, so $2500 for two doors, US dollars. Some of the manufacturers still make wood doors, but they are very expensive and after a few years develop a sag in the middle.
