What this calculator does
This calculator multiplies paintable wall area by the number of coats, then divides by coverage per gallon.
Default coverage
The default coverage is 350 square feet per gallon, which can be adjusted to match the paint label.
Coverage reminder
Actual coverage depends on the paint, surface texture, color change, primer, and application method.
