Frequently asked
- How many studs do I need for a wall?
- Divide the wall length in inches by the stud spacing (16" or 24"), add one, then add about two studs per corner, wall intersection, and door or window opening, plus 10% waste.
- How many plates does a wall need?
- A standard wall has one bottom plate and a doubled top plate — three times the wall length in linear feet.
