Paint Calculator
Add each room you're painting. We'll compute the paintable wall area, factor in coats, and tell you how much paint and primer to buy.
Coverage estimate is 350 sqft per gallon — typical for one coat of latex on a primed wall. Rough or porous surfaces (new drywall, masonry, dark-to-light color change) will use more. Doors are estimated at 21 sqft and windows at 15 sqft each.
