| One area | 100 sq ft |

| Times 1, plus extra | 100 sq ft |
| Square yards | 11.11 |
| Square meters | 9.29 |
| Perimeter of one area | 40 ft |
What else matters here
One hundred square feet is also exactly one roofing square.
The perimeter is 40 feet. Paint follows wall area, which is perimeter times height. A 10 by 10 room with eight foot walls has 320 square feet of wall before the door and window come out, which is 3.2 times the floor area.
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.
