How to Calculate Square Footage
Square footage of a rectangle is length × width, both in feet. For several identical areas, set the quantity. The result also converts to square yards (÷ 9), square meters (× 0.0929) and acres (÷ 43,560).
Odd Shapes
For an L-shape or complex room, split it into rectangles, calculate each, and add them up. Add a price per square foot to estimate flooring, carpet or paving cost.
Working with tile or concrete? Feed the area into the Tile Calculator or Concrete Calculator.
