What is the commonly used spacing for studs in residential structures?

The commonly used spacing for studs in residential structures is 16 inches on center (O.C.). This standard spacing balances structural integrity and efficiency in material use. It allows for proper support of wall coverings, insulation, and any fixtures that may be attached. By spacing studs at 16 inches O.C., builders ensure a strong frame that can adequately support loads while also providing enough space for insulation to be installed without gaps, which enhances energy efficiency.

Using this spacing also aligns with many building codes and practices, making it easier to find pre-manufactured materials like drywall and other finishing products, as they are designed to fit this common stud layout. While other spacings such as 12 inches or 24 inches are used in specific applications, 16 inches O.C. remains the most prevalent choice for typical residential walls, contributing to its reputation as the industry standard.
