Door Opening Width. The width can vary from 12 to 48 inches. The width of a door's rough opening is the width of the door plus 2 inches. The 2 inches accounts for a 3/4-inch jamb board on each side plus 1/2-inch adjustment space. If you are using pre-hung doors, the opening should be 1 inch to 1 1/2 inch wider than the door and its jambs.
