A free, deliberately simple square footage calculator: enter a room's length and width (feet, inches, metres, centimetres or yards) or tap a common room size — small bedroom 10×10, kitchen 12×12, living room 15×20, one-car garage 12×20 — and see the area in square feet, square metres and square yards as you type. Rectangles, circles and triangles, several areas added together for L-shaped rooms, an optional waste allowance for flooring and tile, and a material cost estimate.
