Measure land area in square metres and hectares

Draw a useful boundary and distinguish a map estimate from an official area.

Define the boundary first

Decide what belongs in the measurement: the whole plot, the lawn inside a fence, or cultivated land excluding buildings. Zoom in until the edges can be distinguished. If the entire area barely fits on screen, pan while working rather than placing rough points from far away.

Place points around the shape

Choose area mode and follow the boundary in order. Use more points at curves and fewer on straight sections. Avoid crossing edges. The tool joins the last point to the first, so check this closing segment too. Drawing only a few points around a curve cuts off land and systematically underestimates the area.

Use appropriate units

One hectare is 10,000 m²; one km² is 100 hectares. Divide square metres by 10,000 to get hectares. For example, 25,000 m² is 2.5 hectares. Report a rounded estimate that reflects how confidently you placed the boundary, not every decimal shown by the calculation.

Check the result

Repeat the measurement with a fresh set of points and compare the totals. A visible fence or hedge is not necessarily a legal property boundary. Use official property information and, where necessary, professional surveying for decisions about ownership, construction or sale. Our area method test shows how point density changes a circle's measured area; it does not validate any real parcel.
