Map Measuring Tool — Distance, Area & Address Search
Measure real-world distances and areas on a detailed street or satellite map, down to the foot. Type an address and the map flies right to it, then click to trace a property line, a driveway, a fence run, or a lot — and read the length in feet, yards, and miles, or the area in square feet and acres. Drag any point to fine-tune, and switch between street and satellite imagery.
How to Use
- Type a street address (or place name) in the search box and press Enter — pick a result and the map flies there. Or use “My location.”
- Switch the base map between **Street** and **Satellite** in the layers control (top-right of the map). Satellite is best for tracing lot lines, roofs, and driveways.
- Zoom in close (scroll or the + button) so you can place points accurately, then click **Measure distance** or **Measure area**.
- Click on the map to drop points. Distance shows each segment’s length and a running total; Area shows the enclosed square footage, acreage, and perimeter.
- Drag any point to nudge it, use **Undo** to remove the last point, and read live measurements in the panel — feet/yards/miles or square feet/acres (toggle units any time).
- Click **Clear** to start over. Nothing you draw is uploaded — measurements are computed in your browser.
Measurement
Map data
Street map & address search powered by OpenStreetMap (geocoding via Nominatim). Satellite imagery © Esri, Maxar, Earthstar Geographics. This tool loads map tiles and address lookups from these external services; the points you draw and all measurements are computed in your browser and never uploaded.
How it works
Search an address to fly the map to a place, switch between the street and satellite base maps, then click to measure. In Distance mode each click adds a point and the tool reports every segment’s length plus a running total; in Area mode your clicks enclose a shape and the tool reports its square footage, acreage, and perimeter. Every point you place is draggable, so you can zoom in tight on the imagery and nudge each corner until it lines up exactly with the boundary you’re tracing.
Distances use a geodesic calculation (great-circle distance on the Earth’s surface), and areas use a spherical-earth polygon formula — the same approach mapping apps use — so even a long line or an irregular many-sided lot comes out correct. Results are shown in feet, yards, and miles, or square feet and acres, with a one-click switch to metric. The points you draw and all measurements are computed entirely in your browser; only the map tiles and your typed address are fetched from external services.
Tips for accurate measurements
- Zoom in before you click. The closer you are, the more precisely each point lands on the feature you’re measuring — that’s how you get down to a foot or two.
- Use the satellite layer for land and property. Roofs, driveways, fences, and tree lines are easy to trace on imagery; turn on the street-label overlay if you need names for orientation.
- Drag to fine-tune. Place your corners roughly, then drag each one onto the exact boundary.
- Imagery can be slightly offset. Satellite tiles aren’t survey-grade; for legal boundaries always use a recorded plat or a licensed survey. This tool is a fast, practical estimate.

Frequently Asked Questions
How accurate is the measurement — really down to the foot?
The math is geodesic (it accounts for the curvature of the Earth) and is as precise as the points you click, so on a tight zoom you can measure to within a foot or two. The limit is the imagery, not the calculation: satellite tiles can be slightly offset from the true ground position and your clicks are only as exact as the pixel you tap. For a legal boundary always rely on a surveyed plat — this is a fast, practical estimate, not a survey.
How does the address search work?
When you type an address and press Enter, the tool looks it up with Nominatim, the free geocoder built on OpenStreetMap data, and flies the map to the best match. It searches only when you submit (not on every keystroke) to stay within the service’s fair-use limits. If an address doesn’t resolve, try adding the city and state, or search the nearest intersection and pan from there.
Can I measure the area of an irregular lot?
Yes. Choose Measure area and click each corner of the property in order; the tool encloses the shape and reports its area in square feet and acres plus the perimeter. Drag any corner to line it up exactly with the boundary on the satellite image. The area is computed with a spherical-earth polygon formula, the same approach mapping apps use, so even a many-sided lot comes out right.
Does this work on satellite imagery?
Yes — switch the layers control to Satellite to trace features you can actually see: rooflines, driveways, paths, tree lines, and fences. A street-name overlay is available so you don’t lose your bearings on the imagery. Satellite is usually the most useful layer for land and property measuring.
Is my location or anything I draw sent anywhere?
The points you click and every distance or area are calculated locally in your browser and are never uploaded. The map does load tiles from external map servers and your typed address is sent to the geocoder to look it up — that network traffic is what makes a live map possible. If you use “My location,” your browser asks permission first and the coordinates are used only to center the map.
How do I use the Map Measuring Tool — Distance, Area & Address Search?
Just type your numbers. The answer shows up right away — there is no button to press. Change anything and it updates by itself.
Is it free? Does it work without internet?
Yes to both. It is free with no sign-up, and once the page has loaded it keeps working even with no internet.
Where does my data go?
Nowhere — every calculation runs on your own device. Nothing you enter is uploaded, logged, or stored.
Common Use Cases
Estimate a lot or acreage
Trace a property on the satellite layer to get its square footage and acres before buying, fencing, or listing it.
Measure a fence or driveway run
Click along where a fence, wall, or driveway will go to get the total length in feet for ordering materials.
Plan landscaping & paving
Outline beds, lawns, patios, or a parking area to get the square footage feeding into mulch, sod, gravel, or asphalt estimates.
Check a distance between two places
Search an address, drop a couple of points, and read the straight-line distance in feet, yards, or miles.
Scope a job from the office
Find a client’s address, switch to satellite, and rough out roof, yard, or site dimensions before the site visit.
