Framing & Lumber Calculators
Framing quantities come from spacing and span, and framing cost comes from board feet. These calculators keep the two separate so a spacing change shows up as a lumber cost, not a guess.
Topics in Framing & Lumber Calculators
- Wall Framing Calculators (2 calculators)
Stud count is spacing, openings and corners — not wall length divided by 16. The spacing comparison prices what moving to 24 in. on center actually saves.
- Floor Framing Calculators (2 calculators)
Span tables decide the member, and the member decides the price. Both calculators here start from the span you have rather than the joist you hoped to use.
- Roof Framing Calculators (2 calculators)
Pitch turns a run into a rafter length, and a span into a truss order. Stick framing and trusses are priced from the same roof here.
- Lumber Takeoff Calculators (3 calculators)
Whole-assembly takeoffs: board feet priced at today’s rate, a full garage shell, and the stringer layout that turns a rise into cut lumber.
