Does this include corners?
This is a basic calculation for a straight wall. You should add extra studs for corners, windows, and doors (typically 2-4 extra per opening).
For a 10ft wall at 16" OC, you need 9 studs and approximately 3 x 10ft boards for plates.
Using 16" spacing instead of 24" changes the stud count by approximately3 studs.
Always order 10-15% extra lumber to account for warped boards and cuts. For this project, order 11 studs to be safe.
