## How do you square a corner wall?

Understand the 3-4-5 method.

## How close can a door be to the corner of a house?

Try not to go any closer than 3″ on rough framed walls. You will lose 1/2″ for the drywall, leaving you only a little over an inch after installing the jambs and casing. That is pretty close, and will show up any out-of-level corner. 4″ is a safer bet.

## Are there studs in wall corners?

Studs exist to hold up drywall on interior walls and wood sheathing on exterior walls. This means you will always find a stud, header, or footer on the top, bottom, or corners of walls.

## How many studs are in a corner?

Multiply the total wall length (in feet) by 0.75 (for 16-inch on-center stud spacing). Add three studs for each 90-degree corner. Add four studs for each 45-degree corner. Add two studs for each wall intersection (where another wall abuts the wall you are estimating).
