Calculating drywall installation involves a few key steps. First, measure the total square footage of the walls and ceilings needing drywall. Next, account for waste by adding about 10% to this figure. Divide this total by the standard size of drywall sheets (usually 4x8 feet or 32 square feet per sheet). This gives you the number of sheets needed. Don't forget to consider additional materials like screws, joint compound, and tape.

FAQs & Answers
