Total square footage—

Sheets needed (4x8 = 32 sq ft, +10% waste)—

Drywall screws (estimate)—

Joint compound (5-gal buckets)—

Joint tape (250 ft rolls)—

Always round up to nearest full sheet. Standard rule of thumb: ~1 lb of screws per 500 sq ft, 1 bucket of mud per ~500 sq ft, and 1 roll of tape per ~500 sq ft of drywall.
