Paint Volume Coverage Calculator
Estimate the area covered by a fixed paint volume, an editable spreading rate and number of coats.
Presets and unit changes set the volume and a rough reference rate: 10 m²/L or 350 ft²/US gallon. These are separate estimates, not equivalent rates. Edit the rate using your paint label. Coverage varies with surface, texture, application and paint. This estimates area only; it does not recommend purchases, containers or cost.
A = V × r ÷ c; 1 ft² = 0.09290304 m²
