Rough Openings for Interior Doors | House Designs

Rough openings, also known as construction openings, are the opening in a wall or framing where an architectural element, such as a window, door, stairwell, fireplace or other dimensionally stable component, is framed. It is generally required that the framing portion of the rough openings be compatible with the size of the actual element.

For interior doors, these rough openings need to be accurately measured and cut so that the door will fit snugly into the opening. The industry standard is to measure the interior door dimensions and add two inches to each side for correct sizing of the rough opening.

You should account for the necessary space for casing on each side and any hardware used for closing, such as striking plates and thresholds. It is also important to account for any additional trim, such as baseboards, when measuring for the opening accordingly.
