Paint Coverage Calculator
Calculate how much area a given amount of paint covers.
How It Works
Area covered = Paint volume × Coverage rate.
Example
5 gallons at 350 sq ft/gal covers 1,750 sq ft with one coat.
Frequently Asked Questions
How many sq ft per gallon?
Most paints list 300–400 sq ft/gal. Textured or porous surfaces reduce coverage.
Does coverage change with sheen?
Glossier paints often cover slightly better; flats are a bit thirstier on porous surfaces.
How do I adjust for two coats?
Divide the total area by the number of coats, or double the gallons.
