What is square footage (SF) used to measure?

Square footage (SF) specifically measures area, and it is defined as the total area of a space measured in square feet. This term is commonly used in architecture, real estate, and construction to quantify the size of a floor plan or room. When you calculate the square footage of a space, you multiply its length by its width, the result being expressed in square feet. This measurement is essential for understanding the capacity of a space, determining property value, or assessing the requirements for building materials and furnishings.

The other options represent measurements that do not align with the definition of square footage. Volume refers to three-dimensional space, area in square yards measures a different unit of area, and length measurement pertains specifically to a one-dimensional metric, which is not relevant when discussing square footage.
