Land Area Calculator

For typical yard and garden sizes the calculator is accurate to within about 1%. It uses an equirectangular projection with the Shoelace formula — which is highly accurate for plots spanning a few acres or less. For very large land parcels (tens of acres), consider a professional survey for legal or financial decisions.

Search for your address to jump to your property on the satellite view, then click Draw area. Click along the boundary of your yard to place points, following the edges as closely as you can. Double-click (or click the first point) to close the shape. You can drag any vertex afterward to fine-tune.

Yes. Draw your outer yard boundary first, then click Draw area again and trace the shape you want to subtract (such as a house, shed, or driveway). Each additional polygon is treated as a hole and its area is removed from the total. The breakdown panel will show each shape and the net result.

One acre equals exactly 43,560 square feet. An average suburban lot is roughly 0.2–0.25 acres (about 8,700–10,900 sq ft). A standard American football field (including end zones) is about 1.32 acres.

A square yard is 9 square feet (3 ft × 3 ft). Landscaping materials like mulch, topsoil, and gravel are often sold by the cubic yard, so knowing your area in square yards alongside your desired depth makes it easy to calculate volume without extra conversion steps.

Yes. The map uses single-finger panning and drawing so your finger doesn't get "trapped" scrolling the page. Tap Draw area, then tap points around your yard boundary. Pinch to zoom in for better accuracy. Double-tap the final point (or tap the starting point) to close the shape.
