Exemple de Calcul Étape par Étape

Scénario: Hanging 4x8 drywall in a 12 ft × 16 ft room with 8 ft ceilings, 1 door, 2 windows, and drywall on ceiling.

01

Wall Area: 2 × (16 + 12) × 8 = 448 sq ft gross.

02

Deduct Openings: 1 door (20 sq ft) + 2 windows (30 sq ft) = 50 sq ft deduction -> 398 sq ft net wall.

03

Ceiling Area: 16 × 12 = 192 sq ft.

04

Total Surface: 398 + 192 = 590 sq ft.

05

Add 10% Waste: 590 × 1.10 = 649 sq ft.

06

Calculate Sheets: 649 ÷ 32 sq ft per sheet = 20.28 -> 21 sheets.

Result: Order 21 sheets of 4x8 drywall, ~672 drywall screws (1 five-lb box), 2 rolls of paper tape, and 12 gallons of joint compound.

Drywall Panel Formula

Total Sheets = ⌈ (Net Wall Area + Ceiling Area) × (1 + Waste %) ÷ Sheet Area ⌉

Net wall area is calculated from perimeter times ceiling height minus door and window cutouts. Adding optional ceiling area yields total surface area. Factoring in a 10% waste buffer and dividing by panel size (32 sq ft for 4x8) yields total sheets.

Variables de la Formule

Net Wall Area — Perimeter × Height minus opening deductions
Sheet Area — Square footage per panel (32 sq ft for 4x8, 40 for 4x10, 48 for 4x12)
Fasteners — ~32 screws per 4x8 sheet (screws spaced 12" on ceiling, 16" on walls)

Hypothèses de Calcul

  • Standard 4x8 sheet covers 32 sq ft.
  • Approximately 32 coarse-thread drywall screws (1-1/4") are required per 4x8 sheet.
  • Approximately 0.05 gallons of joint compound is needed per square foot across taping and 3 finish coats.
Trade FAQ

Foire Aux Questions

Questions fréquentes sur les projets de rénovationCalculateur de Plaques de Plâtre (Placo)

Should I hang drywall vertically or horizontally?

In residential construction, hanging drywall horizontally (perpendicular to wall studs) is recommended. It creates fewer seams to tape and finishes flatter across stud variations.

What thickness drywall should I use?

1/2-inch drywall is the standard for interior residential walls and 16-inch on-center ceiling joists. 5/8-inch Type X fire-rated drywall is required by building code for attached garages and firewall partitions.

How many drywall screws do I need per sheet?

Plan for approximately 32 screws per 4x8 sheet. Screws should be spaced 12 inches apart on ceilings and 16 inches apart on vertical wall studs.
