Paint & Stain Calculators
Interior paint, exterior paint, and fence stain coverage calculators.
Paint coverage varies by surface type: smooth drywall covers around 400 sq ft per gallon, rough or porous surfaces closer to 300 sq ft. These calculators account for doors, windows, ceiling height, and the number of coats so you buy exactly what you need.
