Lawn Area Calculator

Break your lawn into simple shapes — rectangles, circles, and triangles — and we'll add up the total square footage. Subtract beds and the house footprint as needed.

Aim for the closest simple shape — being within ±10% is fine for fertilizer and seed planning. For exact measurements, walk the perimeter with a measuring wheel or use Google Maps' built-in measure tool.
