A property measurement tool lets you measure a property from above instead of on foot. Search an address, find it on satellite imagery, and trace the lawn, driveway, roof, lot, or any other area you need. The square footage is calculated as you draw, and each area can be measured on its own.

Measure any part of a property from satellite imagery.

Property measurements are rarely limited to the entire lot. FindPropertySize lets you trace the exact areas you need and calculate their square footage independently.

Measure a lawn for seed or fertilizer, a driveway for sealing, a roof for an estimate, landscaping beds for materials, or the full property for planning. Simply trace the area on the map and the measurement updates automatically.

What you can measureWhat the measurement is for
LawnsCalculate lawn square footage for seed, fertilizer, sod, or treatment estimates.
DrivewaysMeasure concrete or asphalt areas for sealing, paving, pressure washing, or replacement.
RoofsEstimate visible roof area from above for early project planning and quoting.
Landscape areasMeasure mulch beds, hardscapes, patios, and other outdoor spaces separately.
Lots and acreageTrace larger property areas and view measurements in square feet or acres.
Multiple areasCreate separate measurement zones so every part of the property can be calculated independently.

See the calculated square footage as you draw and add additional measurement zones when needed.

A closer look at how to measure a property

Use the clearest satellite view for every property.

A single satellite image is not always the best view of a property. Trees, shadows, image age, and camera angle can make an area difficult to see. FindPropertySize gives you access to multiple available map and imagery sources so you can choose the view that makes the property easiest to measure.

See property boundaries while you measure.

Property boundary data can provide helpful context while measuring a lot, lawn, driveway, or other outdoor area. Turn parcel lines on when available to better understand where a property begins and ends while tracing your measurement.

Parcel line overlays are currently available for U.S. properties only. Measuring works anywhere in the world.

How property lines work, and where they stop being enough

Measure different areas of the same property separately.

Many projects require more than one measurement. Instead of combining everything into a single number, create separate zones for each area you need.

Measure the front lawn, backyard, driveway, landscape beds, roof sections, or other areas individually while still seeing the total measured area for the property.

Front lawn

Measure the turf area separately.

Backyard

Create another zone without affecting the first measurement.

Driveway

Keep hardscape measurements separate from lawn measurements.

Other areas

Add additional zones for the parts of the property relevant to your project.

Useful for homeowners, contractors, and property projects.

Whether you’re planning a project at your own property or preparing an estimate for a customer, an online property measurement can help you understand the size of the job before stepping on site.

Who it is forWhat they measure
Lawn careMeasure turf areas for aeration, overseeding, fertilizer, sod, and lawn treatments.
LandscapingCalculate landscape beds, mulch areas, hardscapes, and outdoor project spaces.
Driveway servicesMeasure asphalt and concrete for sealing, paving, cleaning, coating, or replacement estimates.
RoofingUse visible roof measurements for early estimating and project planning.
Property ownersMeasure your own property before ordering materials, planning improvements, or comparing project options.
ContractorsMeasure customer properties remotely before preparing estimates or visiting the job site.

Measure before you visit the property.

Traditional property measurements often require walking the site with a measuring wheel or relying on rough estimates. Satellite measurement gives you another option when you need the approximate size of an outdoor area quickly.

MethodBest forConsiderations
FindPropertySizeRemote property and project measurementsTrace irregular areas directly from satellite imagery and measure multiple zones.
Measuring wheelOn-site measurementsCan be highly useful on accessible properties but requires visiting and walking the area.
Recorded parcel dataUnderstanding recorded lot dimensions or acreageRepresents parcel records rather than the specific lawn, driveway, roof, or project area you may need.
Professional surveyLegal boundary determinationThe appropriate option when legally established property boundaries are required.

A measured area is not a surveyed boundary.

Measuring from imagery tells you how much of a surface is there. It does not establish where a property line runs, and it is not a substitute for a survey when a legal boundary is what a decision turns on.

Looking for the recorded lot size instead? Find it by address

Measure irregular shapes, not just rectangles.

Real properties rarely fit into perfect rectangles. Curved driveways, irregular lawns, angled lot lines and landscape beds all need more than a length and a width, so FindPropertySize has you trace around the actual visible shape. Add points around the perimeter and the area is calculated from the shape you create.

Property measurement tool FAQs

Can I measure a property online?

Yes. Search an address in FindPropertySize, locate the area on satellite imagery, and trace around it to calculate the square footage. You can measure the entire visible property or specific areas such as lawns, driveways, roofs, and landscape beds.

Is the property measurement tool free?

You can start measuring properties for free with FindPropertySize. Paid options are available for users who need higher usage limits and additional features.

Can I measure irregularly shaped areas?

Yes. You can place multiple points around the perimeter of an irregular shape instead of relying on simple length-by-width calculations.

Can I measure more than one area on a property?

Yes. FindPropertySize supports multiple measurement zones so areas such as a front lawn, backyard, driveway, and landscape beds can be measured separately on the same property.

Can I see property lines while measuring?

For supported U.S. properties, parcel boundary data can be displayed on the map to provide additional context while measuring. Parcel data is intended as a reference and is not a replacement for a professional survey.

How accurate are satellite property measurements?

Accuracy depends on factors including image quality, how clearly the area can be identified, and how precisely the measurement boundary is traced. Satellite measurements are useful for estimates and planning, but they should not replace a professional survey when legally established boundaries are required.

Do I need to download software?

No. FindPropertySize runs in your web browser, so you can search and measure properties online without installing dedicated measurement software.

Can contractors use the property measurement tool?

Yes. Contractors can use FindPropertySize to measure customer properties remotely for estimating and project planning. Our property measurement tools for contractors page covers the contractor-focused features in more detail.

Does the property measurement tool work outside the United States?

Property measurement itself can be used for supported addresses outside the United States. Parcel boundary availability varies, and our parcel boundary data is currently limited to U.S. properties.
