How the math works

Perimeter: 2 × (10 + 12) = 44 ft
Wall area: 44 × 8 ft = 352 sq ft
Ceiling: 10 × 12 = 120 sq ft
Total × 1.10 waste = 519.2 sq ft
4x8 sheets: ÷ 32 = 17; 4x12 sheets: ÷ 48 = 11

Don’t subtract doors and windows on small rooms — the cut-offs rarely get reused. On big rooms subtract openings over 50 sq ft.

Trade pro tips

Hang the ceiling first, then walls top row first so the factory edge meets the ceiling.
Use 1/2" on walls; 5/8" or 1/2" ceiling board on ceilings framed 24" OC.
Stagger end joints and keep them off door and window corners.
