What is the maximum wall stud spacing allowed for gypsum sheathing in conventional light-frame construction?

In conventional light-frame construction, gypsum sheathing plays a critical role in providing structural stability and fire resistance while also contributing to energy efficiency. The maximum wall stud spacing allowed for gypsum sheathing is typically 16 inches on center. This spacing ensures that the sheathing is adequately supported, minimizing the risk of sagging or failure. It also allows for a proper attachment of the sheathing to the studs, providing a robust wall assembly that meets code requirements and performance standards.

Studs spaced 16 inches apart effectively distribute loads and enhance the overall strength of the wall construction. When studs are spaced further apart, like 24 inches or more, the support for the gypsum sheathing is reduced, which can lead to increased movement, cracking, or loss of effectiveness in fire resistance. Additionally, codes and standards often specify this spacing to guarantee that the materials perform as intended and meet safety standards for building construction.
