In the vinyl siding industry, a “square” refers to 100 square feet of siding. This measurement is the standard unit used for estimating and pricing siding projects. For example, a house with 1,500 square feet of exterior wall area requiring new siding would need 15 squares of vinyl siding.
Understanding this unit of measurement is crucial for homeowners planning exterior renovations. It allows for accurate material estimations and budget planning. Historically, this standardization simplified communication between contractors and manufacturers, streamlining the building process. Accurately calculating the required number of squares prevents material shortages during installation and avoids unnecessary surplus.
