Area calculator map
draw the shape, get the area.

Draw any polygon on real satellite imagery and get the exact area instantly. Square metres, hectares, or square kilometres — switch between units freely. No account needed to try.

Most area calculators make you type in dimensions. Terramapr lets you draw the shape directly on the satellite image of the actual land — so the area you calculate is the real area, not an estimate based on rough side lengths.

Draw any shape: rectangular plots, irregular farm paddocks, L-shaped building sites, curved natural boundaries. Every vertex you place is geo-referenced, and the area calculation uses geodetic math — corrected for the curvature of the earth. Important for anything over 2–3 ha where flat-map calculators start drifting.

You can calculate multiple areas in one project, give each shape a label, and see the total. Export a PDF with all shapes, labels, and measurements on the satellite map.
