Ceiling Paint
Plan paint for a ceiling from the room footprint.
About Ceiling Paint
The ceiling area is the room length times width, and the gallons are rounded up to whole cans after accounting for coats. Ceilings are painted separately from walls, and a small dry-touch-up project can still need a full gallon.
