Area Measurement App

Marea is a free area measurement app for iOS and Android. Measure any area on a satellite map — land plots, farm fields, rooftops, construction sites, sports grounds — and get instant results in acres, hectares, square metres, square feet and more.

Why Marea?

There are plenty of area measurement apps. Marea stands out because it’s:

  • Fast — Drop pins and read the area. No menus to navigate, no setup.
  • Accurate — Built on high-resolution satellite imagery and GNSS positioning.
  • Multi-unit — Switch instantly between acres, hectares, square metres, square feet, square kilometres and square miles.
  • Shareable — Export measurements as KML files that work with Google Earth and most GIS tools.
  • Offline-capable — Once map tiles are cached, you can keep measuring without a signal.

Measure Anything

Marea’s area measurement tools are designed to handle anything from a small flower bed to a thousand-acre farm.

Small Areas

Measure rooms, gardens, driveways and rooftops. The app handles small areas down to a few square metres without losing precision.

Property & Land

Verify lot sizes, measure boundary-to-boundary distances, and document property dimensions for listings, contracts and insurance.

Farm Fields

Calculate field acreage for crop planning, irrigation, subsidies and yield analysis. Save fields with names and revisit them year after year.

Construction Sites

Estimate site area, building footprints and material coverage for quotes, permits and earthworks.

Irregular Shapes

Marea measures any polygon — there’s no limit on the number of points. Trace curving boundaries, exclude carve-outs, and the area updates as you go.

How the App Works

  1. Open Marea on iOS or Android
  2. Find your area using satellite or standard map view — search by address or use GPS to locate yourself
  3. Drop pins by tapping the map (or walk the boundary using GPS)
  4. Read your result — area, perimeter and distance update in real time
  5. Save, share or export — keep a library of measurements or export as KML
