Not a perfect rectangle?
Measure an L-shaped room, a triangular corner or a lot with a diagonal side with the square footage calculator. It works in feet, inches, yards or meters, and subtracts closets, stairs or any area you do not want to count. For painting, the wall area matters more than the floor: see the paint calculator.
