Paint Calculators
Estimate paint quantities and project costs before you start rolling. These calculators cover gallon counts by room size, number of coats, and coverage rate, plus full project cost estimates that include primer, supplies, and optional labor. Use them to buy the right amount of paint and avoid mid-project trips to the store. A standard gallon covers 350 to 400 square feet on a smooth wall with one coat. Textured walls and ceilings cut that to 300 square feet or less. Getting the count right before checkout saves both money and time.
