Land Acreage Calculator

Draw any shape on the map to measure its area in acres, square feet and hectares. Free, instant, and no account required.

How to measure land area on a map

Zoom to the parcel you want to measure, then tap or click once for each corner of the boundary. Tap your first point again to close the shape and the area is calculated immediately. Drag any point to adjust it — the total updates live. On a phone or tablet, move the map with two fingers.

Acres, square feet and hectares

One acre is 43,560 square feet, or roughly 4,047 square metres. A hectare is 10,000 square metres, about 2.47 acres. This tool reports all three so you do not have to convert by hand.

Frequently asked questions

How accurate is this acreage calculator?
Areas are computed on the WGS84 ellipsoid from the shape you draw, so the maths is exact. Accuracy depends on how precisely you trace the boundary against the satellite imagery. It is a good estimate, not a survey.
Is this land area calculator free?
Yes, completely free with no account required. A free Land Owl account adds real parcel boundaries so you do not have to trace them by hand.
Can I measure a property without knowing its boundaries?
Draw around what you can see on the satellite imagery for an estimate. For exact recorded boundaries, a free Land Owl account shows surveyed parcel lines for most US counties.
