Square Footage Calculator

Calculate area in square feet and square meters from length and width.

Square footage is the most common way to measure floor area in the United States, Canada, and the United Kingdom. It is essential for real estate listings, flooring estimates, painting, and property taxes.

To find the square footage of a rectangular space, simply multiply the length by the width. For irregularly shaped rooms, divide the floor into rectangles, calculate each separately, and add them together.

This calculator also converts the result to square meters for countries that use the metric system. One square meter equals approximately 10.764 square feet. Knowing both units is useful when comparing international real estate prices or ordering materials from global suppliers.
