Wall

Rough-opening sizes. "From start" is the distance from the start of the wall to the left edge of the rough opening (for a T-wall, to the face of the partition). Header sizes are your choice for estimating lumber — size load-bearing headers from your local code's header table or an engineer.

Layout marks
Hook the tape on the start of the wall and mark the near edge of each stud at: 15 1/4, 31 1/4, 47 1/4, 63 1/4, 79 1/4, 95 1/4 in (centres at 16″ multiples). Marks inside an opening become cripples; marks that land on a king or jack stud are skipped.
Planning estimate only. Header sizes, stud grades, load paths and fire blocking depend on loads, species, grade and your local building code. Verify with your building department or a licensed professional before you buy or build.
