What Does a 30 × 80 Door Mean?
A 30 × 80 door is commonly identified by a nominal width of 30 inches and a nominal height of 80 inches. This size is commonly encountered in residential interior door applications.
The nominal size is useful for identifying a door product, but it does not necessarily represent the exact outside dimensions of the entire prehung unit.
30 × 80 Door Actual Dimensions
The actual dimensions depend on whether you are measuring the door slab, the prehung unit, the frame, or another part of the assembly. Manufacturer specifications should be used for exact measurements.

There is no single rough-opening dimension that applies to every 30 × 80 door product. The required opening depends on the specific prehung unit and manufacturer's installation requirements.
