How to measure a lawn on the map
Type the address and choose it from the list. Pick “Lawn”, then tap each corner of the grass on the satellite map. Tap the first corner again to close the shape. You can drag any corner to adjust it, and trace several areas (front and back yard) to add them up.
Measure only the grass you'll actually mow or treat: leave out the house, driveway, patios and planting beds. Beds and the driveway can be measured separately with their own buttons.
Square feet and acres
One acre is 43,560 square feet. The calculator shows both, so you can compare with lot sizes from county records, which usually include the house and hardscape, not just the lawn.
How accurate is it?
The size is worked out from the corners you place on the satellite image, so it's as accurate as your tracing. Trees can hide the edge of a lawn, and satellite photos can be a few years old, so for an exact figure check on site. For quoting, a careful trace is usually close enough to price the job.
