About Square Feet
A square foot (ft²) is an imperial unit of area equal to a square with sides of one foot (12 in × 12 in or 144 in²). It is the standard for measuring floor space in the United States and some other countries. A typical bedroom is 100-150 ft², and the average American house is roughly 2,000-2,500 ft². This unit dominates real estate listings, flooring sales, and construction in countries using imperial measurements.
