Metal stud & track calculator

Formulas

• Base stud count = ceil(wallLength_in / spacing_in) + 1
• Openings add = (doors + windows) × 2 (king + jack; cripples not included — add manually for large openings)
• Corner add = outsideCorners × 2 + insideCorners × 3
• Stud count = ceil((base + openings + corners) × (1 + stud_waste))
• Stud LF total = stud_count × wall_height
• Track LF = wallLength × 2 × (1 + track_waste) (when top+bottom track is selected)
• Track pieces = ceil(track_LF / 10) (standard 10-ft stick)
• Steel weight (lbs) = stud_count × wall_height × PLF(gauge)

PLF values used (3-5/8" stud)

• 25 ga: 0.54 lb/ft
• 20 EQ ga: 0.72 lb/ft
• 20 ga: 0.85 lb/ft
• 18 ga: 1.10 lb/ft
• 16 ga: 1.38 lb/ft

What this does NOT account for

• Head-of-wall deflection track (slotted, double-leg) — bill separately.
• Jamb stud doublers, header boxes, and sill studs for oversize openings.
• Bridging, clips, anchors, fasteners, and powder-actuated pins.
• Shaft wall C-H studs or CT-stud composite systems.
