What LotSite measures

Start with the big number: your total lot area, in square feet and acres. Enter an address, see the property on satellite imagery, and trace your boundary on the measuring grid — the total calculates as you paint.

Then go granular. A paintable grid lets you measure individual yard sections — grass, driveway, patio, garden beds, pool, and structures — each with its own square footage, so a fertilizer quote uses your lawn area, not your whole lot. A dedicated fence mode traces your fence perimeter in linear feet, and a tape-measure mode gives point-to-point distance measurements anywhere on the map.

None of it assumes your property is a tidy rectangle. Irregular shapes and boundaries — pie lots, flag lots, five-sided corner parcels — measure exactly the same way: paint what's there, read the number. For the methods behind it all, see how to measure your property.
