What is Square Footage?

Square footage is a measurement of area expressed in square feet (sq ft). It is calculated by multiplying length by width and is the standard unit of area measurement in real estate, construction, and interior design in the United States. In metric countries, the equivalent measurement is square meters (sq m). This calculator supports both units and provides instant conversion between them, making it useful for international property comparisons and material estimates.
