Nail or screw 2 x 6 jambs to the framing on the top first and then the sides of the rough opening.

However if you are putting bricks thick river rock stones marble or anything else on both sides that is more than 1 thick you will want the rough opening the same.
If the door is 7 tall frame the opening 7 1 5.
