Paint Coverage Calculator

Paint Calc helps you estimate exactly how much paint to buy before starting your next painting project. Choose from three project types: a single accent wall, a full room with four walls, or an overhead ceiling. Enter your dimensions and subtract doors and windows so you only buy paint for the net area you actually paint. Adjust coat count, paint coverage per gallon, and a waste buffer up to 25%. The app instantly calculates total gallons needed and recommends a practical mix of 5-gallon buckets, 1-gallon cans, and quart cans. Use quick-start presets for popular room sizes, save up to 20 custom room scenarios, and reload saved snapshots anytime with one tap.
