Painting

Know how many gallons before you shop.

All three calculators use the same coverage math — area × coats ÷ coverage rate — the difference is how you tell us the area. Pick the one that matches what you already know.

Paint CalculatorGallons needed from a flat area you already know.Room Paint CalculatorGallons for a full room — dimensions, doors and windows.Wall Paint CalculatorGallons for a single wall or accent wall.

Which one do I need?

Room, wall, or already-measured area.

Use the room paint calculator for a full room — it subtracts doors and windows for you. Use the wall paint calculator for a single wall or accent wall. If you already know the exact square footage you're painting, the plain paint calculator skips the room math entirely.
