How much does a quart of paint cover?

A quart of wall paint covers about 88 to 100 square feet in one coat, and half that in two. The arithmetic, and what a quart covers at every coverage rate.

About 88–100 ft² in one coat, or 44–50 ft² in two.

A quart is a quarter of a gallon, and a gallon of wall paint is rated for 350–400 ft². With a roller's waste taken off, one coat comes nearer 80 ft².

How that is worked out

  1. A quart is 0.25 of a gallon, so it covers a quarter of what the can says a gallon does.
  2. At 350–400 ft² per gallon, that is 88–100 ft² for a single coat.
  3. Two coats spread the same quart over half the wall: 44–50 ft².

Worth knowing

  • The figure on the can is measured on a smooth, primed surface. Bare drywall, fresh plaster and anything textured all drink more, so take the low end of the range or below it.
  • A quart is the right size for trim, a door, a small bathroom's touch-ups or a test patch. Past about one accent wall in two coats, a gallon usually costs barely more than the quarts it replaces.
  • Rolling loses a little paint to the roller and the tray, which is why the last column comes in under the can's figure. Brushing loses less and spraying loses a lot more.
