Which type of studs can be spaced on 24-inch centers in most jurisdictions?

The spacing of studs in wall construction is influenced by the type of stud being used and the structural requirements dictated by building codes. In many jurisdictions, 2x6 studs can be spaced on 24-inch centers, especially in light-frame construction. This spacing helps provide adequate structural support while allowing for greater insulation value and efficiency in covering the walls with sheathing.

Using 2x6 studs on 24-inch centers is commonly approved because they have a higher load capacity compared to smaller dimensions and can effectively support the load in both residential and commercial structures. The broader spacing can also facilitate improved energy efficiency, as it allows for more insulation in the wall cavity when compared to narrower stud spacing, which is especially beneficial in regions with colder climates.

In contrast, while 2x4 studs are typically encouraged to be spaced 16 inches on center for standard framing practices, they might not provide the same level of structural integrity if spaced as widely as 24 inches. Larger stud sizes like 2x8 and 2x10, while they can be useful in specific structural situations or for particular applications, are less commonly utilized with broader spacing in conventional framing practices due to additional considerations like weight and the bending moment they need to accommodate.

Thus, 2x
