Google Maps Area Calculator
A Google Maps area calculator lets you draw a polygon, circle, or rectangle on a satellite map to measure the area of any land parcel, lot, field, or property. Results are calculated using GPS coordinates and the Shoelace formula (Gauss's area formula) for polygons.
The calculator converts GPS coordinate differences to real-world distances using the Haversine formula, which accounts for the curvature of the Earth. Results are displayed in sq ft, sq meters, acres, and hectares.
Accuracy Note
Map-based area calculations are accurate to within 1–3% for most residential and agricultural properties. For legal boundary disputes, use a licensed land surveyor.
How to Measure Land Area on a Map
- Search for your property: Type the address or location name into the map search bar.
- Zoom in: Use satellite view for the most accurate boundary tracing.
- Draw your area: Click or tap to place points along the boundary of the land you want to measure. Close the shape by clicking the first point.
- Read the result: The calculator displays the total area in sq ft, acres, sq meters, and hectares.

Frequently Asked Questions
Right-click on the map in Google Maps and select "Measure distance," then draw the boundary. Alternatively, use a dedicated Google Maps area calculator tool that supports polygon drawing and automatic area calculation in multiple units.
Map-based calculators are accurate to within 1–3% for most properties. Accuracy improves with higher zoom levels and satellite imagery. For legal purposes, hire a licensed surveyor.
Yes. Draw the property boundary on the map and the calculator converts the area to acres automatically. 1 acre = 43,560 sq ft.
In the US, acres are standard for land. In most other countries, hectares are used. This calculator shows sq ft, sq meters, acres, and hectares simultaneously.
Trace the irregular boundary by placing points at each corner or bend of the property line. The more points you use, the more accurate the area calculation will be.
