What is Square Footage Calculator?
A square footage calculator measures the area of a room, yard, or space by multiplying length by width. It handles rectangular, triangular, circular, and complex multi-section areas, making it essential for home improvement projects, real estate, and construction planning.
How to Use
- Select the shape of the area (rectangle, triangle, circle, or L-shape)
- Enter the measurements in feet, inches, or meters
- For irregular shapes, divide into sections and calculate each one
- View the total area in square feet, square meters, and acres
Formula
Rectangle: Area = Length x Width; Triangle: Area = (Base x Height) / 2; Circle: Area = pi x Radius^2
Frequently Asked Questions
- How do I calculate square footage for an L-shaped room?
- Divide the L-shape into two rectangles, calculate each area separately, and add them together. Measure each section's length and width independently.
- How do I convert square feet to square meters?
- Divide square feet by 10.764 to get square meters. For example, 500 sq ft / 10.764 = 46.45 sq meters.
- How much square footage do I need for my project?
- It depends on the project. Always add 10% extra for waste and mistakes on materials like flooring, paint, or tile.
