Rough carpentry needed to install your door
There are a few basic steps to create your rough opening for your door. Some doors on load bearing walls need a header that will support the weight above the door. The header size is determined by the width of opening and the weight above the doorway. The rough opening should be 2 inches wider then the door size. The height of the rough opening should be framed one and a half inches taller then the door and threshold. The rough opening should be framed plumb and level. When framing you have king studs or full length studs on each side with a 2 x 4 or 6 depending on wall thickness cut for rough opening height fastened to the door opening side. This shorter piece will hold up the header or head piece. In wide openings the shorter support 2 x 4 or 2 x 6 may have to be doubled or tripled to bear the weight the header holds up. Remember your header length will be the rough opening plus 3 inches for every support 2 x 4 or 2 x 6 on a side. If you have one support per side it will be 3 inches longer and if you have two it will be 6 inches longer and so on.
