Google Earth Acreage Calculator
Measure acreage on satellite imagery and take it into Google Earth. Trace any boundary on the map below to get the acreage instantly, then use the Marea app to export your measurement as a KML file that opens directly in Google Earth.

Measure Acreage, Then Open It in Google Earth
- Trace the boundary on the satellite map to measure the acreage.
- Export as KML in the Marea app — a single tap.
- Open in Google Earth — the KML file drops your measured area straight onto the globe, with the shape and acreage intact.
KML (Keyhole Markup Language) is the native format Google Earth uses for geographic data, so your measured plots, boundaries and points carry over exactly.
Why Use KML with Google Earth?
- Share measurements — Send a KML file to colleagues, clients or contractors and they see the exact same boundary.
- Archive plots — Keep a permanent, openable record of every parcel you measure.
- Combine tools — Measure quickly here, then annotate, tour or overlay in Google Earth.
- Round-trip — Import existing KML boundaries back into Marea to measure their acreage.
Acreage in Every Unit
As you trace a boundary you get the area in acres, hectares, square meters, square feet, square kilometers and square miles — switch instantly, no conversion needed. For quick number-only conversions, try the acres to square feet calculator.
Take It Into the Field
The Marea app is where the KML export lives, alongside live GPS, offline maps and saved measurements. It’s available on iOS and Android — measure a field on foot, then open the result in Google Earth back at your desk.
Frequently Asked Questions
Can Google Earth calculate acreage?
Google Earth Pro has a polygon measure tool, but it's clunky for quick land measurement. Measuring here is faster, reports directly in acres and hectares, and you can export the result as a KML file that opens in Google Earth.
How do I get my measurement into Google Earth?
Measure the area, then export it as a KML file using the Marea app. Opening that KML file in Google Earth places the exact boundary and acreage onto the globe.
What is a KML file?
KML (Keyhole Markup Language) is the file format Google Earth uses to store geographic shapes and points. It lets you move measured boundaries between mapping tools without losing accuracy.
Do I need to sign up to measure acreage?
No. Measuring in the browser needs no sign-up. The Marea app, which adds KML export, is available on iOS and Android.
