Area Calculator – Quickly Calculate the Area of Shapes Like Squares, Rectangles, Circles, Triangles, and More to Support Math, Construction, Design, and Everyday Measurements.
The following calculators evaluate the area of seven common shapes.
The Area Calculator helps you quickly find the area of different 2D shapes using simple formulas. Whether it’s a rectangle, circle, triangle, or more complex polygons, this tool provides accurate results in just a few steps. It’s ideal for students, teachers, architects, engineers, and anyone needing precise area measurements.
✅ Rectangle / Square – length × width or side²
✅ Circle – π × radius²
✅ Triangle – ½ × base × height
✅ Parallelogram – base × height
✅ Trapezium – ½ × (a + b) × height
✅ Ellipse – π × a × b (semi-major × semi-minor axis)
✅ Polygons – custom formulas based on side lengths
Easy input for lengths, widths, radius, base, and height
