Framing, Lumber & Stairs

Framing estimates combine a layout with the sizes and spacing of individual members. Wall studs are counted from wall length, on center spacing, corners, openings, and extra framing around doors and windows. Floor joists and beams also depend on span, loading, material grade, and support conditions. A count of boards is useful for ordering, but it does not establish that a member is structurally adequate. Use the approved design and local building requirements for those decisions. Stairs need consistent rise and run across the flight. The total height between finished floors sets the number of risers, while the available horizontal distance limits tread depth. Stringers, balusters, and guard details each answer a separate question. For decking, distinguish the deck surface from the supporting framing. A board foot measures lumber volume; plywood is usually purchased by sheet size. Before placing an order, note actual board dimensions, stock lengths, cuts, and waste. Use the framing tool for layout counts, stair tools for the geometry of a flight, and board foot or lumber tools when comparing quantities of wood.
