When framing a door with metal studs, the rough opening width should exceed the door width by how much?

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

Answer: (A)

When framing a door, you need a rough opening that is wider than the door itself to accommodate the jamb, shims, and finishing materials so the door can swing freely and stay square. With metal studs, the standard practice is to leave about two and a half to three and a half inches more than the door width. That extra space accounts for the thickness of the jamb assembly, shim adjustments to plumb and square the frame, and the drywall or plaster that will cover the sides. The exact amount within this range depends on the specific door and jamb you’re using and how much finish material you plan to add. Choosing less clearance can make it hard to install and align the door, while this range gives you enough room to work with.
