Calculate Land Area on a Map of Australia
Draw a shape to measure land in hectares, acres, or square metres. Ideal for property, farming and planning.
Draw a shape on the map - a polygon or rectangle - and this tool calculates its area using geodesic mathematics that account for the Earth's curvature. Results are shown in hectares, square metres, square kilometres, acres, and square feet. Commonly used by real estate agents measuring blocks, farmers assessing paddock sizes, and homeowners checking suburb block dimensions. Switch to satellite view for the clearest boundary visibility, and draw multiple shapes to get individual and combined totals.
Free Online Land Area Calculator for Australia
The MapTools Area Calculator is a free tool that lets you measure the area of any shape drawn on a map of Australia. Simply draw a polygon or rectangle around the land you want to measure, and instantly see the area in hectares, square metres, square kilometres, acres, or square feet.
Whether you're a real estate agent measuring block boundaries, a farmer calculating paddock sizes, or a homeowner curious about your suburb block area, this tool makes it easy to get accurate measurements without any specialist software.
Who Uses This Tool?
Measure block sizes and yard areas for listings.
Calculate paddock sizes in hectares for crop and stock planning.
Estimate land area for construction projects and planning applications.
Measure garden or lawn area for landscaping projects.
Verify block or acreage sizes when purchasing rural or suburban land.
Quick area estimates for initial site assessments.
Supported Units
The Area Calculator supports both metric and imperial measurements:
- Metric: Hectares (ha), square metres (m²), square kilometres (km²)
- Imperial: Acres, square feet (sq ft), square miles
Australia's official unit for land area is the hectare, shown by default, but acres remain common in rural and lifestyle-block listings - toggle between metric and imperial in the sidebar. Perimeter (total boundary length) is calculated automatically alongside area.
How to Use
- Navigate to your location - Zoom and pan the map to find the area you want to measure
- Select a drawing tool - Click the polygon (for irregular shapes) or rectangle tool in the top-right corner
- Draw your shape - Click on the map to place points. For polygons, click to add each corner, then click the first point to close the shape
- View results - The area appears instantly in the sidebar and as a popup on the shape
- Draw more shapes - Add multiple shapes to calculate a combined total area
- Edit if needed - Use the edit button to adjust your shapes
Accuracy
This tool uses the WGS84 coordinate system and calculates geodesic area, which accounts for the Earth's curvature. For most practical purposes, the measurements are highly accurate.
For legal or surveying purposes, always verify measurements with a licensed surveyor. This tool is designed for estimates and general planning, not legal documentation.
Frequently Asked Questions
How accurate are the area measurements?
The tool uses the WGS84 coordinate system and calculates geodesic area, which accounts for the Earth's curvature. For most practical purposes the measurements are highly accurate. For legal or surveying purposes, always verify with a licensed surveyor.
Can I measure irregular shaped land?
Yes. Use the polygon tool to draw any shape by clicking to add corner points. Close the shape by clicking the first point again. You can also use the rectangle tool for regular shapes.
Does this tool use hectares or acres?
Both. Hectares are Australia's official metric unit for land area, shown by default alongside square metres and square kilometres. Acres are still commonly used for rural and lifestyle blocks - switch to the Imperial toggle to see acres, square feet, and square miles instead.
Can I measure more than one area at a time?
Yes. Draw multiple shapes and the tool will calculate each area individually as well as the combined total. Useful for measuring separate paddocks, lots, or sections of a property.
Does this work for large areas like farms and stations?
Yes. The geodesic calculation works accurately at any scale, from suburban blocks to large rural properties and stations. Switch to satellite view to see paddock and fence boundaries more clearly when measuring farmland.
