How Big Is My Yard? Measure Yard Size by Address
Enter your address, trace your lawn on a free aerial photo, and get square feet, acres and fence length. The number comes from your own tracing, so you can see exactly what was measured.
Measure your yard
Find your home, then tap the corners of your lawn.
Tap each corner of your lawn on the photo. Drag a dot to adjust it.
Your traced area
—
Tap at least 3 corners to see the area.
Imagery metadata for the initial lookup location: date unavailable. The point-query record may not identify the displayed mosaic or a panned area. Map services and data available from U.S. Geological Survey, National Geospatial Program. USGS NAIP Plus includes NAIP and high-resolution orthoimagery; resolution varies.

How to measure your yard by address
- Find your home. Type your address, or use your current location if you’re standing in the yard. The address pin comes from the U.S. Census Bureau’s address file and usually lands on the street in front of the home, so pan the map to your yard.
- Zoom in until you can see where the grass meets the driveway, beds and fence.
- Tap each corner of the area you want to measure. On a phone, you can instead line up the crosshair and press “Add corner at crosshair” so your finger doesn’t hide the spot. Drag any dot to fix it; Undo removes the last one.
- Measuring front and back separately? Press “Add another area” and trace the next one. The total adds them up.
- Read your numbers: square feet, acres and outline length, plus rough quantities for fertilizer, sod, mulch and fencing.
How accurate is a yard measurement from an aerial photo?
The area is calculated from the points you place, on the same model of the Earth that GPS uses, so the math itself adds no meaningful error. What limits the result is the tracing and the photo:
- Photo detail: Image detail varies across NAIP Plus imagery. Soft edges can make tracing uncertain; place points where the lawn clearly changes.
- Trees and shadows: Collection conditions vary. Trees, shadows and other obstructions can hide an edge; trace an estimate only where you can judge it, and check obscured areas on site.
- Photo age: Imagery can predate changes on the property. Metadata for the initial lookup location may be unavailable and may not identify the displayed mosaic or a panned area; it cannot confirm whether a recent patio, fence or planting appears.
Under the result you’ll see how much the number would change if every edge were off by 3 feet. For a big order like sod, measure on site before you buy.
This is not a survey or your property line
You’re measuring what you trace, not your legal lot. To see your lot boundary from county parcel records, try property lines by address. Only a licensed survey is authoritative.
Where the aerial photo comes from
People often search for a “satellite” view of their yard. This tool displays aerial imagery from the USGS NAIP Plus service, which combines the USDA National Agriculture Imagery Program (NAIP) and high-resolution orthoimagery. Image detail varies. Using this tracing tool does not require an account.
The imagery comes from different collection programs with different dates and detail. In a September 2026 check of 12 state capitals, the newest metadata records were dated 2017 to 2023; that historical sample is not a current coverage or freshness guarantee.
Your privacy: Address suggestions send what you type through BuildFolio to Geoapify. When you search, the address goes to the U.S. Census Bureau geocoder. USGS receives the viewed map-tile areas and the initial lookup coordinates for imagery metadata. The device-location option uses your coordinates for USGS requests without a Census address lookup. This tool keeps drawings in page memory and does not create an account or submit drawings to BuildFolio. Its explicit usage events contain coarse labels and counts, not the raw address, coordinates or drawing. This does not describe logging or retention by the surrounding website or external services.
Turn your yard size into a shopping list
| Project | How to use your number |
|---|---|
| Lawn fertilizer | Divide your square feet by the coverage on the bag. Bags are often sized for 5,000 or 15,000 sq ft; the label is what counts. |
| Grass seed | Seed rates are listed per 1,000 sq ft and differ for new lawns and overseeding. Divide your area by 1,000 and multiply by the rate on the bag. |
| Sod | Pallets usually cover 400 to 500 sq ft. Add about 5% for cuts and ask your supplier for their pallet size. |
| Mulch or topsoil | Cubic yards = square feet × depth in inches ÷ 324. At 3 inches deep, 1,000 sq ft takes about 9.3 cubic yards. |
| Fence | Use the outline length, then subtract gates and any side that already has a fence or wall. |
Frequently asked questions
How can I find out how big my yard is by address?
Enter your address above, pan to your yard on the aerial photo, and tap the corners of your lawn. The tool shows the area in square feet and acres as you go, plus the outline length.
Can I measure my yard with Google Maps?
Google Maps on a computer has a Measure distance tool (right-click the map), and Google Earth has a ruler that can measure area. This page lets you trace on USGS NAIP Plus aerial imagery and adds acres, fence length and material estimates.
How accurate is a yard measurement from an aerial photo?
The math adds no meaningful error; the result is as good as your tracing and the photo. Image detail varies, trees can hide edges, and the imagery may be several years old. The tool shows how much a 3-foot miss on every edge would change your number.
How old is the aerial photo of my yard?
The caption reports a dated metadata record, when available, for the initial lookup location. That point-query record may not identify the displayed mosaic or a panned area; date information can be unavailable. A September 2026 check of 12 state capitals found records dated 2017 to 2023, not a current coverage or freshness guarantee.
Is my traced yard the same as my property line?
No. You’re measuring what you trace, not your legal lot. County parcel maps show approximate lot lines, and only a licensed survey is authoritative.
Does BuildFolio save my address or drawing?
Address suggestions send what you type through BuildFolio to Geoapify. When you search, the address goes to the U.S. Census Bureau geocoder. USGS receives the viewed map-tile areas and the initial lookup coordinates for imagery metadata. The device-location option uses your coordinates for USGS requests without a Census address lookup.
