How many inches on center can utility-grade studs be spaced in wall framing under light-frame construction?

Utility-grade studs in wall framing are typically spaced 16 inches on center in light-frame construction. This spacing is a standard practice because it provides adequate support for various wall finishes and load-bearing needs while maintaining structural integrity.

Spacing studs at 16 inches allows for a comfortable balance between material efficiency and strength, ensuring that wall assemblies can effectively support drywall, sheathing, and any loads they may bear, such as shelves or cabinets. This distance also aligns well with standard sizes of insulation batts, simplifying the insulation process during construction.

While other spacing options, such as 12, 18, or 20 inches, may occasionally be used in specific design scenarios or depending on local codes, they do not represent the typical standard for utility-grade studs in light-frame construction. Thus, the adoption of 16-inch spacing is a widely accepted standard in the industry.
