open door frame
The most simply constructed door frame consists of a head supported by two vertical stiles, without a sill across the bottom. These are called open door frames and are used for interior doors, where a raised threshold at the bottom of the door could hinder access.
closed door frame
Exterior door frames will need to have a sill or threshold; these are called closed door frames. This horizontal piece at the bottom of the frame completes the seal around the door. The door sits on the sill when it’s closed.

sidelight door frame
Luckily, single, double and sidelighted doors usually are made in standard sizes. Unless your house is very old, you should be able to find a replacement door/sidelight unit that will fit perfectly in the existing wall opening
