Measuring an irregular area
Choose “Irregular: measure in parts”. Split the outline into rectangles, circles, triangles and other shapes that do not overlap, measure each, and the calculator adds them. Take out a flower bed, a tree ring or a patio inside the area with “Leave out an area.”
For a triangle, measure the height at a right angle to the base, not along a sloping side. For an L-shaped or U-shaped area, measure the full outside length and width, then the part that is missing.
Square feet, square yards and acres
One square yard is 9 square feet. One acre is 43,560 square feet. One square meter is 10.76 square feet.
Use the area in a material calculator
The buttons under the result carry your area into the mulch, topsoil, gravel, sod, grass seed and paver calculators, so you do not measure twice.
