Land Area Calculator — Measure Area on a Map

Measure the area of any parcel, lot, field, or roof by outlining it on the map. MeasureMaps calculates the enclosed area and the perimeter using spherical geometry, so results stay accurate even for large regions. Read the area in square meters, square kilometers, hectares, square feet, or square miles, and convert to acres in one step.

How to measure land area on a map

Outline the shape and MeasureMaps does the math:

  • Search for the property or location you want to measure.
  • Select the area tool and click each corner of the boundary.
  • Close the shape to see the total area and the perimeter around it.

Acres, hectares, and square feet

Area is shown in square meters and square kilometers (metric) or square feet and square miles (imperial), and exports also include hectares. To read a parcel in acres: 1 acre = 4,047 m² = 0.405 hectares = 43,560 sq ft, and 1 hectare = 2.471 acres.

Perimeter included automatically

Every area measurement also reports its perimeter — the total length around the boundary — so you can size a fence, wall, or edging at the same time. The perimeter is included in all exports alongside the area.

Who uses a land area calculator

Measuring area from a map saves a site visit for:

  • Real estate — lot size, plot area, and land listings.
  • Agriculture — field and paddock area for seeding and yield.
  • Roofing and solar — roof area and panel layout estimates.
  • Landscaping and construction — turf, paving, and material quantities.
  • Surveying and planning — quick parcel and zoning checks.

Frequently asked questions

How do I measure land area on a map?

Select the area tool and click each corner of the parcel, then close the shape. MeasureMaps shows the enclosed area and the perimeter, with units in square meters, square kilometers, hectares, square feet, or square miles.

How do I measure acreage?

Outline the land with the area tool and read the value in hectares (1 hectare = 2.471 acres) or square feet (1 acre = 43,560 sq ft). Exports include the raw square-meter value so you can convert precisely.

Does it calculate the perimeter as well as the area?

Yes. Every area measurement includes both the enclosed area and the perimeter of the boundary, and both are saved in your GeoJSON, KML, CSV, and JSON exports.
