King Stud - Full-Height Stud at Wall Openings Guide

A king stud is the full-height wall stud that runs alongside a door, window, or other framed opening.

What It Is

A king stud forms the outside edge of a rough opening and works with the jack stud and header to carry loads around that opening. It runs continuously from the bottom plate to the top plate, helping keep the wall straight and giving the opening a stable nailing surface.

Because it is part of the wall framing layout, its position affects rough opening width, sheathing attachment, and how the header assembly is fastened. In load-bearing walls, a damaged or missing king stud can weaken the opening and the surrounding wall section.

Where It Is Used

King studs are used at doors, windows, cased openings, and other framed interruptions in stud walls. They appear in both interior and exterior framing wherever a header and side support are needed.

How to Identify One

Look for the full-height stud on the outer side of a rough opening. Unlike the jack stud, it does not stop under the header and instead continues all the way to the top plate.

Replacement

Replacement is needed when the stud is rotted, badly split, cut for an oversized utility run, or altered during previous remodeling. If the wall is load-bearing, repairs should be done with temporary support in place so the opening does not move while the framing is restored.
