Which option correctly states the rough opening width difference for a door framed with metal studs?

• A. 3/4 inch
• B. 3/4 to 1 1/2 inches
• C. 2 1/2 to 3 1/2 inches
• D. 1 1/2 to 2 1/2 inches

Answer: (C)

Rough openings must be wider than the door itself to leave room for the door jamb, shims, and installation tolerances. When metal studs are used, you typically need more clearance because the metal track and jamb assembly add width and don’t provide the same forgiving bite as wood framing. That’s why the recommended width difference for a door framed with metal studs is about 2 1/2 to 3 1/2 inches. This range ensures there’s enough space to plumb and square the frame, install the jambs, and accommodate shims and finish materials on both sides. The smaller options wouldn’t provide enough room and could lead to binding or misalignment.
