Painting Smarter

Buying exactly the amount of paint you need prevents waste and saves money. Our calculator accounts for standard surface areas subtracted by openings like doors and windows to give you a clinical estimate.

Coverage Estimates

Standard wall paint typically covers 350 to 400 square feet per gallon. If you're painting porous surfaces like high-texture plaster or brick, you might need up to 20% more paint.
