How to Measure Your Lawn

Hire a Surveyor

Professional land surveys cost $300–$800 and take days to schedule. Accurate for legal purposes but overkill for buying fertilizer.

$300–$800

DIY Tape Measure

Measure length × width for rectangular areas. For irregular shapes you'll need to break the lawn into sections, measure each, and add them up. Time-consuming and error-prone.

Lawn Sizes

What's the Average Lawn Size?

The average U.S. residential lawn is approximately 10,000 square feet, or about a quarter of an acre. That said, actual lawn area varies wildly depending on where you live and the size of your lot. Townhome and condo lots typically have 1,500 to 4,000 square feet of grass, while a standard suburban quarter-acre lot usually offers 7,000 to 10,000 square feet of lawn after subtracting the house footprint, driveway, and other hardscape.

For half-acre properties and larger, you're looking at 15,000 square feet or more of grass. At that scale, the difference between buying one bag too many and buying five bags too many adds up fast. Getting an accurate measurement before you shop saves real money over the course of a season.

LotSite makes this easy by automatically subtracting the house footprint and hardscape when you paint the grid. Instead of guessing or measuring by hand, you get a precise breakdown of grass, driveway, patio, and garden bed area in about 30 seconds.
