Square Footage Calculator

What is a Square Footage Calculator?

A square footage calculator is a free online tool designed to help you quickly determine the area of rooms, plots, lands, or surfaces in square feet (sq ft), square meters, square yards, and other units. Whether you are planning home renovations, buying flooring materials, calculating paint requirements, or estimating construction costs, this tool simplifies complex math into a single click.

How to Calculate Square Footage?

The formula for square footage depends heavily on the geometric shape of the space you are measuring:

• Rectangles & Squares: Multiply the length by the width ($Length \times Width$). For example, a room 12 feet long and 10 feet wide equals 120 square feet.
• Triangles: Multiply the base by the height and divide by two ($\frac{1}{2} \times Base \times Height$).
• Circles: Multiply the square of the radius by Pi ($\pi \times r^2$).
