These instructions on measuring, making and installing a shed door are suited to the Buildeazy free plan 'How to build a 8'x10' storage shed'
but the same principles can be applied to many shed designs.
Info: The rough opening
The rough opening fig.1a is the opening in a wall frame that allows for a door (or window).
The rough opening is trimmed (surrounded) by framing lumber which consists of trimmer studs on the sides and header (lintel) at the top.
The rough opening must be big enough to accommodate the door, the door jamb and a little bit to spare.
The jamb is the frame or trim that surrounds the door.
