Lawn Area Calculator

Measure a lawn by combining rectangles, triangles, circles and trapezoids and subtracting areas that are not grass.

Lawn sectionsAdd lawn sections and subtract patios, beds or other areas that should not be included.

How it works

The calculator totals the selected lawn shapes and subtracts any excluded shapes.

lawn area = added areas − excluded areas

Worked example

A 50 ft × 30 ft rectangular lawn is 1,500 ft², or about 0.034 acres.

Assumptions

  • Measurements are horizontal plan dimensions.

Limitations

  • Irregular natural edges may require approximation with several simple shapes.
