Frequently Asked Questions
How many sheets of drywall do I need?▾
Measure total wall and ceiling area in square feet, then divide by sheet size (32 sqft for 4x8, 48 sqft for 4x12). Add 10-15% for waste from cuts and mistakes. A typical 12x12 room with 8-ft ceilings needs about 18 sheets of 4x8 drywall.
How much joint compound do I need?▾
Plan for approximately 0.05 gallons of joint compound per square foot of drywall. A 5-gallon bucket covers about 100 square feet of finished joints. For a standard room, 1-2 buckets is typical.
What thickness drywall should I use?▾
1/2-inch is standard for walls. 5/8-inch is required for ceilings (sag-resistant) and fire-rated walls (Type X). 1/4-inch is used for curved walls. Moisture-resistant (green board) is used in bathrooms and kitchens.
