Calculate area of geometric shapes with formulas and visual guides
Calculate areas of squares, rectangles, circles, and triangles easily.
Example: 5m × 5m square = 25 m² area
Support for meters, feet, inches, centimeters, and millimeters.
Feature: Automatic unit conversion for area results
See the mathematical formula and visual representation of each shape.
Educational: Learn geometry while calculating
Handle parallelograms, trapezoids, ellipses, and rhombuses.
Professional: Perfect for construction and design work
You can use meters, feet, inches, centimeters, or millimeters. The area result will be in square units (m², ft², in², etc.).
For irregular shapes, try breaking them into smaller regular shapes and add their areas together, or use the closest matching shape as an approximation.
Area measures the space inside a shape (square units), while perimeter measures the distance around the outside of a shape (linear units).
All calculations are mathematically precise. Results are displayed to 2 decimal places for practical use, but internal calculations maintain full precision.
Yes! This calculator is perfect for determining floor areas, wall surfaces, material quantities, and other construction measurements.
Triangle height is the perpendicular distance from the base to the opposite vertex. It's not necessarily one of the triangle's sides.
Radius equals diameter divided by 2. So if diameter is 10m, radius is 5m. Enter 5 in the radius field.
For rectangular rooms, measure length and width, then use the rectangle calculator. For L-shaped rooms, break into rectangles and add the areas.
Yes, for regular shaped lots. For irregular land parcels, you might need surveying tools or break the land into approximate regular shapes.
Yes, all formulas used are standard geometric formulas taught in mathematics and used in engineering and construction.
