How to frame an inside corner

When you’re framing a wall, inside corners can throw a curve at you. (I know, we’re stretching it, but couldn’t resist.) In addition to building a strong wall, you need to provide a nailing surface for the drywall or other wall finish.

If you simply erect one wall, and then erect the next one perpendicular to it, you won’t have a place to nail.

Over the years, carpenters have come to rely on a variety of methods.

The three-stud corner

This provides a very sturdy corner, and it leaves enough of an overhang (when dealing with 2x4s) for a drywall nailer. But it has a couple of drawbacks. For exterior walls, it doesn’t allow for insulation in the corner. And if you have to run wires through it, drilling is going to be a big – and a tricky – task.

The almost-three-stud-corner

By sandwiching short lengths of blocking between two studs, you allow a gap for wiring and for some insulation. But… is this really necessary?

The two-stud return

This method works for whatever dimension lumber you’re working with, allows for a nailer, and allows for some insulation.
