What Is the Size of a Rough Opening for a 36-Inch Pre-Hung Door?

The rough opening for a pre-hung 36-inch door is 38.5 by 82 inches. The rough aperture should be one inch wider than the door’s frame and three-quarters of an inch taller than the door itself.

A pre-hung door includes an attached frame. Many carpenters use pre-hung doors because they reduce installation time. They are slightly more expensive than door slabs with the frame connected separately. In a rough opening, the door and frame are placed. It consists of a vertical wall stud on either side of the door and a header, which spans the top of the aperture.

A carpenter instals shims, which are thin strips of wood, between the door frame and wall studs to ensure that the door is hung accurately. Shims are required since most frame openings are not completely square. The door would not close correctly without shims. The door is then levelled and affixed to the frame with small finishing nails.

The installation of a pre-hung door involves simple equipment and a few essential components. This project can be accomplished by anyone with fundamental carpentry skills.
