In wall framing, what term describes an upright post in the framework of a wall for supporting sheets of lath and plaster or wallboard?

• A. Purlin
• B. Ridge
• C. Stud
• D. Rafter

Answer: (C)

In wall framing, the upright member that runs vertically to support wall coverings is a stud. These vertical members connect the bottom plate to the top plate, carry loads down to the floor and foundation, and provide attachment points for drywall or plaster. They’re typically spaced at regular intervals (often 16 inches on center) and sized as 2x4 or 2x6 lumber. Other terms describe different members: a purlin is a horizontal roof or ceiling support; a ridge is the top horizontal line where roof slopes meet; a rafter is a diagonal roof beam. So the vertical wall member that supports the wall coverings is the stud.
