Google Maps Acreage Calculator
Paste your boundary points (latitude, longitude), one pair per line. The polygon is automatically closed from the last point back to the first point.
Tip: You can collect points in Google Maps by right-clicking locations and copying coordinates.
How to use this Google Maps acreage calculator
This tool helps you estimate land area from coordinate points and instantly convert the result into acres, square feet, hectares, and square meters. It is useful for land buyers, farmers, developers, and anyone planning fencing, irrigation, or site layout.
Step-by-step process
- Open Google Maps and find your parcel or field.
- Collect boundary points in order around the property perimeter.
- Paste each point as
latitude, longitudeon a new line. - Click Calculate Acreage.
- Review area and perimeter output in multiple units.
What this calculator computes
The calculator treats your points as a closed polygon on Earth and uses a spherical area method to estimate the enclosed land area. It also calculates perimeter using the haversine distance formula between each pair of consecutive points.
Output includes
- Total area in acres
- Square meters and square kilometers
- Square feet
- Hectares
- Total perimeter in meters, kilometers, and feet
Accuracy notes for land measurement
Google Maps acreage estimates are excellent for planning and quick analysis, but they are not a legal survey. Small errors can come from point placement, imagery alignment, and boundary interpretation.
To improve accuracy
- Use more points along curved boundaries.
- Zoom in before copying coordinates.
- Follow parcel corners in sequence (clockwise or counterclockwise).
- Avoid crossing lines in your polygon.
- Double-check copied latitude and longitude values.
Common use cases
This map area calculator is practical for many day-to-day decisions:
- Estimating acreage for buying and selling land
- Farm planning, crop rotation, and grazing sections
- Calculating material quantities for fencing and irrigation
- Project budgeting for grading or landscaping
- Comparing parcel sizes quickly across locations
Acre conversion quick guide
- 1 acre = 43,560 square feet
- 1 acre = 4,046.8564224 square meters
- 1 hectare = 2.47105381 acres
- 1 square kilometer = 247.105381 acres
Frequently asked questions
Can I use this for irregular property boundaries?
Yes. The tool is designed for irregular polygons. Just add enough points to represent the shape closely.
Do I need to repeat the first point at the end?
No. The calculator automatically closes the shape by connecting the last point back to the first.
Is this the same as a legal survey?
No. This is an estimate for planning purposes. For legal boundaries, title work, or permits, use a licensed land surveyor.
Final thoughts
If you need a fast and practical way to measure land area from map coordinates, this Google Maps acreage calculator gives immediate, readable results. It is simple enough for quick checks and detailed enough for practical planning.
