Estimate how much paint you need for your walls, doors, and windows.
Material estimates are approximate. Actual quantities may vary due to waste, site conditions, design changes, material dimensions, labor methods and local pricing. Always verify with a qualified contractor or supplier before purchasing materials.
Net Wall Area = (Wall Length × Height) - (Doors × 21) - (Windows × 15). Gallons = (Net Area × Coats) / 350.
Result: Net area: 393 sq ft, Paint: 2.25 gallons
A gallon of paint typically covers 350-400 sq ft for one coat.
Primer is recommended for new drywall, dark colors, or stained surfaces.
It is recommended to buy 10-15% extra paint beyond the calculated amount to account for spillage, waste, and having matching paint for future touch-ups.
Darker colors and flat finishes often require more coats for full coverage, while lighter colors and glossy finishes typically provide better coverage with fewer coats applied.
