Square Footage Calculator
Calculate area for rectangles, circles, triangles, and trapezoids
How It Works
Calculate the area of a space in various shapes including rectangles, circles, triangles, and trapezoids.
Square footage is the measurement of area in square feet. It is commonly used in real estate, construction, home improvement, and interior design to quantify the size of rooms, buildings, and land.
This calculator supports four common shapes: rectangular or square areas, circular areas (such as round tables or gardens), triangular spaces, and trapezoidal areas. Simply select the shape that matches your space, enter the required dimensions, and the calculator will compute the total area.
Results are shown in square feet, square meters, square yards, and square inches. Understanding square footage is essential for estimating flooring materials, paint coverage, landscaping supplies, and HVAC requirements.
