How much paint do I need for a ceiling?

A 12 x 12 ft ceiling is 144 square feet: about 2 quarts for one coat or 1 gallon for two, at 350 square feet per gallon.

A flat ceiling’s area is simply the room’s length times width. The table uses 350 sq ft per gallon; textured (popcorn or knockdown) ceilings soak up more, so allow 250 to 300.
