Studs = ceil(length ÷ spacing) + 1, plus 2 per corner and 2 per door for kings/jacks. Plates = 3 runs (double top) or 2, in 16-ft boards.
Enter wall length and height, set spacing and openings studs, plates, sheets, mud, and tape price themselves live.
Net drywall = wall area × sides − door/window deductions (21 / 15 sq ft), plus 10% cutting waste.
One 4.5-gal mud bucket and one 250-ft tape roll cover ~500 sq ft of board each.
Sheets = area ÷ 32 (4×8)
Wall area is 2 x (12+16) x 8 = 448 sq ft. After deducting a door (21 sq ft) and two windows (30 sq ft) and adding 10% cutting waste, you need about 13 4x8 sheets per side.
31 studs for the run (40x12/16 rounded up, plus one), plus 2 per corner and 2 per door for kings and jacks — 43 total for a 40-ft wall with 4 corners and 2 doors.
Budget one 4.5-gallon bucket of mud and one 250-ft roll of tape per 500 sq ft of installed board.
10% cutting waste on the net board area, after deducting 21 sq ft per door and 15 sq ft per window.
Plates run three times the wall length — one bottom plate plus a doubled top plate — or two runs where a single top plate is allowed, figured in 16-ft boards.
