Square Footage Calculator
Calculate the area of any room or space in square feet. Ideal for flooring, painting, landscaping, and real estate measurements.
About the Square Footage Calculator
The Square Footage Calculator is a versatile tool for computing the area of any flat surface. It supports rectangles, triangles, circles, and L-shaped or irregular rooms by breaking them into simpler shapes. Whether you are calculating the floor area for new carpeting, measuring wall space for paint, or determining lot coverage for a building permit, this tool provides accurate results instantly.
This calculator is essential for homeowners planning renovations, real estate agents listing properties, contractors estimating materials, and students learning geometry. It eliminates the need for manual calculations and reduces the risk of arithmetic errors, especially for complex room layouts. You can input measurements in feet and inches, and the calculator converts everything to square feet automatically.
Beyond basic rectangles, the tool handles triangles for gable ends, circles for rounded features, and multiple combined shapes for irregular rooms. It also provides conversions to square meters for international projects or metric-based material specifications.
How to Use the Square Footage Calculator
Calculate area in a few simple steps:
- Select the shape of the area you want to measure: rectangle, triangle, or circle.
- Enter the dimensions in feet and inches for the selected shape.
- For complex rooms, add multiple shapes and the calculator will sum their areas.
- Click Calculate to see the total square footage.
- The result also shows conversions to square meters for reference.
For rooms with closets or alcoves, calculate each section separately and add them together. For L-shaped rooms, divide the space into two rectangles and enter both. The calculator combines all shapes to give you the total area.
