When not part of a braced wall line, what is the maximum spacing for flat studs in an interior nonbearing wall?

The maximum spacing for flat studs in an interior nonbearing wall when they are not part of a braced wall line is 16 inches on center. This spacing is important for ensuring the structural integrity and stability of the wall, allowing it to support its own weight and any fixtures that may be attached to it.

Nonbearing walls serve as partitions and do not contribute to the overall structural support of the building. Therefore, they need to maintain sufficient strength without being overly laden. The 16-inch maximum spacing standard helps to balance the need for lightness and ease of construction with durability and capability to withstand occasional stresses, like hanging items or minor impacts.

Options suggesting larger spacings, such as 18 or 24 inches, exceed the recommended standards and could lead to insufficient support for wall coverings, insulation, and other components, potentially resulting in sagging, bowing, or failure under load. Therefore, 16 inches is established as a safe and effective standard for this type of construction.
