Area Calculator

The Area Calculator lets you measure the area of any location by drawing directly on an interactive map. Click to place points around the boundary of your chosen region, and the tool will calculate the enclosed area instantly in square meters, square kilometers, acres, hectares, and square feet. It's ideal for estimating the size of land parcels, fields, or other irregular shapes. The tool also shows the perimeter of the area and offers options to customize markers and fill colours. You can save or export your results for reference, making it a practical tool for many uses.
