How it works

Enter your wall length, height, stud spacing, lumber size, plate layers, and prices. The calculator counts layout studs plus end or corner studs, converts top and bottom plates into stock boards, estimates fire-block rows and pieces for taller walls, and totals board feet and cost. Switch to Project Mode to enter several walls and see rolled-up studs, plates, and cost for the full job.
