Square feet, yards and m² for rooms, triangles, circles and L-shaped areas.
Area Calculator by Atlas works out square footage the way you measure it: 14' 6" by 11' 9 1/2".
EASY TO READ
• Room size → square feet. Big numbers and a big keypad on one screen; triangles, circles, L-shapes, more areas, waste and cost are under More.
SHAPES
• Rectangles and squares: length × width
• Triangles: base × height ÷ 2
• Circles: from the diameter
• L-shaped rooms: overall size minus the missing corner
ADD AREAS TOGETHER
• Add as many areas as you need and get one total
• Each area shows its own square footage, so you can check your takeoff
UNITS
• Feet, inches and fractions: 12' 6", 12ft 6-1/2in, 150 (inches) or 3/4
• Or metric, in metres
• Results in square feet, square yards and square metres
WASTE AND COST
• Add a waste percentage for cuts and pattern loss
• Enter a material price per square foot to estimate the cost
The app shows every formula it uses. Results are estimates; measure twice and check the manufacturer's waste guidance before ordering.
