Calculate exactly how much paint you need for your project
This calculator estimates paint coverage by calculating total wall area, subtracting doors and windows, and accounting for the number of coats and paint quality.
Standard coverage rates: Most paints cover 350-400 square feet per gallon on smooth, previously painted walls. New or dark colors may require more coats.
Tips: Always buy 10-15% extra for touch-ups and waste. Two coats are recommended for best results and color coverage.
