Add up the square footage of one room or a whole project without reaching for a separate calculator. Enter a room length and width in feet to see its area instantly, then add more rooms to build a running total that is perfect for ordering flooring, paint, insulation or estimating cleaning and heating. Each room you add shows its own area, and the grand total updates as you type, so you can model an entire floor plan in one place. The tool also converts the total to square meters for anyone working in metric or comparing against a listing that uses it. Odd shaped rooms can be split into rectangles and entered as separate rows, then summed automatically. Everything runs locally in your browser, so your floor plan and measurements stay on your device with nothing sent to any server.
