What is the most common spacing for non-loadbearing metal C-shape studs?

The most common spacing for non-loadbearing metal C-shape studs is 16 inches on center. This spacing has become a standard practice in the construction industry for several reasons. It allows for the efficient use of materials while providing enough structural support for the wall assembly, including the installation of drywall and any finishes.

Studs spaced at 16 inches on center help ensure that the drywall sheets can be properly secured, allowing for effective load distribution and minimizing the risk of sagging or cracking. Additionally, this spacing provides adequate support for electrical wiring and plumbing, facilitating easier installation of utilities within the wall system.

While other spacings, such as 12, 18, or 24 inches on center, may be used in specific applications or for different construction requirements, 16 inches on center strikes a balance between structural integrity and material efficiency, making it the preferred choice for most non-loadbearing wall assemblies.
