When framing for a 9′ X 7′ garage door, do you make the rough opening 9′ X 7′ or do you allow extra for trim so that the finished opening is 9′ X 7′? Thanks, Stanley. Nail or screw 2 x 6 jambs to the framing on the top first and then the sides of the rough opening. After installing the jambs, your garage door opening should now be the same size as the garage door.
