Framing, Drywall & Roofing
For wall stud & sheathing at 16 ft long × 20 ft high, the estimate includes 10% waste. At 16 in on center, budget 15 studs, 52.8 linear ft of plates and 11 sheathing panels.
Each opening budgets two king and two jack studs, with two header plies bearing 1½″ at each end. Check the framing plan for bearing, header sizing, cripple studs and sill stock.

Use this worksheet for one straight wall measuring 16 feet along its plate and 20 feet from bottom to top. Start by drawing the wall in elevation. Put both ends, each opening and the direction of adjoining walls on that drawing. Label the spacing from the approved framing plan, then mark the centerline of each regular stud. The spacing setting changes a material count. The appropriate spacing depends on the member size, loading and wall design.
Measure the wall in its own plane. The width input represents wall height on this worksheet. A room footprint belongs on a separate sketch showing the individual wall runs. Estimate one wall at a time when walls differ in height or spacing. Keep a list of the shared corners so that the framing required at intersections can be reconciled after all the straight runs have been counted.
At sixteen inches on center, convert the wall length to 192 inches and divide by sixteen. Round the number of intervals up and add one end stud. For this wall the regular layout contains 13 studs before waste. The worksheet applies 10% and rounds to whole pieces, giving 15 studs. Check the layout against the stock length you plan to buy, particularly if the ceiling height changes partway along the run.
The plate allowance covers one bottom plate and two top plates. Three runs times 16 feet, plus the allowance, gives 52.8 linear feet to budget. A linear-foot total is a starting point for the cut list. Place joints according to the project detail and work out how many stock boards the runs actually need. A bundle with enough total footage may still be short of a usable long piece.
Wall area is 16 times 20, giving 320 square feet on one face. Divide the area with waste by thirty-two square feet per four by eight panel and round upward to get 11 panels. Before purchase, draw the sheets over the framing elevation. A wall just taller than a full sheet needs a second course. Short strips may be reusable on another wall if their edges land where the detail requires support.
The International Residential Code framing tables distinguish bearing and nonbearing conditions, supported stories, stud size and unsupported height. Use the locally adopted edition and the project drawings for the actual member selection. Track headers, bearing studs, trimmers, hold-downs and blocking as separate items. Opening schedules and bracing details control those quantities. A percentage added to the straight-wall stock provides a cutting allowance but cannot identify the members required at a particular opening.
At purchase, group the takeoff by species, grade, size, treatment and stock length. Plate material in contact with a slab may carry a different specification from upper plates. Mark delivery bundles so the crew can find the wall packages without moving the entire load. For a new wall supported on a slab or footing, confirm that the supporting work has passed the required inspections. The wall material count can be prepared independently of the foundation and subgrade details.
Enter one straight wall at a time. Stud spacing and member sizes should follow the approved framing plan.
Count both end studs, then separately list corner assemblies, openings, backing and intersecting walls.
The plate estimate includes one bottom plate and two top plates. Check splice locations against stock lengths.
The sheathing estimate covers one wall face in 4 × 8 panels. Review panel joints and cuts before ordering.
At 16 in on center, budget 15 studs, 52.8 linear ft of plates and 11 sheathing panels. The estimate includes 10% waste.
At 16 inches on center, a straight wall uses 16 layout studs including both ends. With 10% allowance the order is 18. At 24 inches on center the corresponding counts are 11 and 13.
Spacing is measured between stud centerlines. Choose the spacing shown on the framing plan, including any closer spacing at individual locations.
With no openings entered, the estimate covers one straight wall. Enter windows and doors to include king and jack stud allowances. Add corners, backing, sills and cripples from the framing plan.
Enter rough opening sizes. The estimator deducts their area from sheathing and estimates displaced studs, king and jack stock, and two-ply header footage. Confirm member sizes and bearing on your framing plan.
