How to measure your lot size
Lot size is the total area of your property, including the house, yard, driveway, and everything inside the parcel boundary. Search your address, trace the parcel, and instantly measure it in square feet or acres.
It’s the number used in real estate listings, tax records, permits, and property research. If you’ve ever wondered, “How big is my property?” this is the measurement you’re looking for.

Square feet to acres
Property sizes are often listed in either square feet or acres. One acre equals 43,560 square feet, and your measurement can be viewed in either unit.
“How big is my property?”
When people ask, “How big is my property?” they’re usually asking for the total size of the parcel — not just the house or lawn. Measuring the parcel boundary gives you that answer.
Parcel lines vs. the fence
Fences, hedges, and tree lines don’t always match the recorded property boundary. That’s why parcel boundaries are helpful — they show where the recorded lot ends, not where landscaping happens to be.
Parcel boundaries are excellent for planning and estimating. For legal boundary disputes or surveys, always consult a licensed surveyor.

Will my measurement match my deed?
It’s very close when you follow the parcel lines, and plenty accurate for planning. For legal purposes, use the recorded survey or deed.
What if parcel boundaries aren’t available?
Parcel lines currently cover U.S. properties only. You can still trace the visible boundary from the satellite photo — fences, tree lines, and driveways usually make the lot edges clear.
