What else matters here
Two hundred and eighty square feet, which is a primary bedroom in a new build or a good sized family room.
At this size the paint quantity stops being obvious, because paint follows the walls and not the floor. The perimeter here is 68 feet, so at nine foot ceilings the walls are 612 square feet gross, roughly 550 after a door and a couple of windows come out. Two coats is 1,100 square feet of coverage, which is four gallons at 350 square feet a gallon, and that is before the ceiling. The floor area, 280, has nothing to do with it.
What this calculator assumes
- Length times width, times how many areas are that size. For an L shaped room, split it into two rectangles and run this twice.
- Square yards are square feet divided by nine, which is how carpet is still quoted in much of the country.
