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. Measure the width and height of your door opening in feet and inches. This determines the size of door needed. The rough opening measure the same size as the door.

While building a new garage it is better to check available sizes, make a selection and create a rough opening according to manufacturer specifications. Well, normal garage doors measure 8 x 7 feet, 9 x 7 feet and 10 x 7 feet all around. When you build a garage make it bigger as well as the rough opening so it can accommodate bigger vehicles. While garage doors close against rough openings, other types of residential doors fit inside the opening. Therefore, before determining a rough opening for the garage door, you need to decide upon the jamb material you’ll use.
If you are building a garage, the rough opening should be the same size as the door you wish to install. The door will be placed on the inside of the opening and weather strip can be used to prevent rain and wind from penetrating any gaps.
