Frequently Asked Questions
The calculator uses the shoelace formula (Gauss’s area formula) to determine the area of a polygon when the coordinates of its vertices are known. It works for both regular and irregular polygons by summing the cross products of each pair of coordinates.
You can enter coordinates in decimal degrees format (e.g., 40.7128° N, -74.0060° W). The calculator accepts both positive and negative values, where positive values are north/east and negative values are south/west.
You can add as many points as needed to define your polygon. The calculator automatically handles the calculation for any number of vertices. For best results, enter points in order (clockwise or counter-clockwise) around the perimeter.
Yes, the calculator provides accurate results for both small and large areas. For very large areas (over 100 km across), the results may have slight inaccuracies due to the Earth’s curvature, but for most practical purposes it’s sufficiently precise.
Yes, this calculator is perfect for measuring property areas using GPS coordinates or survey points. However, for official legal documents, always consult with a licensed surveyor.
