Under conventional light-frame construction, utility-grade studs must not exceed what spacing on center?

In conventional light-frame construction, the standard spacing for utility-grade studs is typically 16 inches on center. This spacing is commonly used in both residential and commercial projects as it provides a balance between structural integrity and material efficiency.

Having this spacing allows for adequate support and helps to distribute loads effectively across the structure. By keeping the studs at this specified distance, it also standardizes the placement for other components such as insulation, wall finishes, and electrical wiring, ensuring that these elements can be installed easily and without conflict.

While there are alternative spacing options, such as 12 or 24 inches, they are less common for utility-grade studs in typical wall construction. The choice of 10 inches is generally unnecessary for standard applications, leading to waste of materials and increased costs without significant benefit. Thus, 16 inches on center is widely recognized as the appropriate and most efficient standard for utility-grade studs in conventional light-frame construction.
