== Typical Wall Framing ==== Frame a Doorway ==* When framing up the wall, mark the location for the door rough opening. That opening should be 2.5 inches wider and 1 3/4 inches higher than the door itself. As an example, a 30-inch door will have a rough opening of 32.5 inches by 6 feet 9 3/4 inches.* Saw through the top of the sole plate (bottom horizontal framing member of the wall) at the inside edges of the king studs (the regular length studs to which header members are attached). * Measure and cut two jack studs (studs that do not run the full height of the floor, used to support heavier framing at both sides of a door, window, or other opening) so they are 1 and 3/4 inches longer than the height of the door.
