Calculate the area of any geometric shape with formulas, visualizations, and unit conversions
Area is the measure of space inside a two-dimensional shape, expressed in square units. It quantifies the amount of surface a shape covers on a plane.
Area calculations are essential in construction, landscaping, painting, flooring, agriculture, and design. They help determine material needs, costs, and spatial planning.
Regular polygons (equal sides), irregular shapes, curved shapes (circles, ellipses), and composite shapes each require specific formulas and measurement approaches.
Calculations assume perfect geometric shapes. Real-world objects may have irregularities. Complex shapes may need decomposition or integration methods for accurate results.
Fundamental in geometry education from elementary through calculus. This calculator supports homework, test preparation, and conceptual understanding of spatial relationships.
Used in architecture, engineering, real estate, manufacturing, art, and science. Essential for project planning, resource estimation, and spatial analysis.

The ancient Egyptians used area calculations for land surveying after Nile floods 5000 years ago
Understanding area concepts is crucial for 87% of technical and trade professions
Square the linear conversion factor. For example, 1 meter = 100 cm, so 1 m² = 10,000 cm². For imperial units, 1 ft² = 144 in², and 1 yd² = 9 ft².
Break irregular shapes into regular shapes (triangles, rectangles), calculate each area separately, then add them together. For curves, use integration or approximation methods.
Use precise measuring tools like laser measures or surveying equipment. Take multiple measurements and average them. For large areas, GPS or drone mapping provides high accuracy.
Most area formulas come from geometric proofs. Rectangle area (length × width) is fundamental. Other shapes derive from this through decomposition, transformation, or calculus.
Flooring and carpet installation, painting walls, land surveying, solar panel placement, garden planning, fabric cutting, and determining property taxes based on square footage.
Graph paper for visualization, CAD software for precision, GIS tools for land areas, measuring wheels for perimeters, and digital planimeters for irregular shapes.
You cannot directly calculate area from perimeter alone except for circles. Different shapes with the same perimeter can have different areas. You need additional measurements.
Area measures flat 2D shapes. Surface area measures the total area of all faces of a 3D object. A cube has area for each face, but surface area for all six faces combined.
