Also, what do jack studs do? Jack studs and king studs Jacks, sometimes called trimmers, fit under each end of a header, and they transfer the load that the header carries down to the bottom plate and the framing beneath. Nailed to the jacks are full-height studs called king studs; they support the assembly between the plates.

How do you put a header on jack studs?
The header rests on two "jack" studs abutted by two "king" studs. Leave the area beneath the header open when framing in a door, or add the "cripple" studs at the bottom of the sill if framing in a window. Add cripple studs above the door or window opening set at the same framing intervals used in the walls.
