Square Footage Calculator
Multiply length by width to get square feet. Enter the measurements in feet (use decimals for inches: 6 inches is 0.5 ft) and the calculator converts the area to square yards, square meters and acres.
For an L-shaped room, split it into two rectangles, work out each one, and add them together.
How it’s calculated
- Square feet = length (ft) × width (ft).
- Square yards = square feet ÷ 9. Square meters = square feet × 0.0929.
- To convert inches to feet, divide by 12: 10 ft 6 in = 10.5 ft.
