What is the maximum allowable stud spacing for interior non-bearing walls?

The maximum allowable stud spacing for interior non-bearing walls is 24 inches on center (o.c.). This spacing is designed to provide adequate strength and support for the wall while allowing for efficient use of materials and insulation. Non-bearing walls do not support any loads from the roof or ceilings above, which means they do not require the same level of structural integrity as bearing walls.

By allowing a spacing of up to 24 inches, builders can create walls that are both functional and economical. This wider spacing also facilitates easier installation of drywall and other finishes, as fewer studs need to be positioned and secured. Standards are established in building codes to ensure safety and performance, and in this context, the maximum spacing for non-bearing walls reflects a balance between material efficiency and structural performance.

Most other spacing options are either closer than needed for non-bearing walls or exceed the practical needs and building codes established for such structures.
