Square footage is the floor area of a room. You need it for flooring, rugs, heating and cooling, and listing a home.
Measure wall to wall along the floor in both directions. A room 15 feet by 11 feet is 15 × 11 = 165 sq ft.
If a wall is 11 feet 6 inches, divide the inches by 12: 6 ÷ 12 = 0.5, so it's 11.5 feet. A 15 ft × 11 ft 6 in room is 15 × 11.5 = 172.5 sq ft.
Draw the room on paper and split it into two rectangles. Measure each one and add them together.
| Main section | 20 × 12 = 240 sq ft |
| Side section | 8 × 10 = 80 sq ft |
| Total | 320 sq ft |

In Squarely, add each rectangle as its own room and the app adds them for you.
If the flooring goes into the closet, measure it as a separate rectangle and include it. If it doesn't, leave it out.
Measure in meters and multiply the same way. To convert, 1 square meter is about 10.76 sq ft. Squarely has a Meters switch if you'd rather work in metric.
