What is the maximum spacing allowed for studs in wall construction?

The maximum spacing allowed for studs in wall construction is determined by various standards, including the National Building Code of Canada (NBCC) and other relevant guidelines. The spacing of 600mm on center (o.c.) is the most widely accepted standard for stud framing in wood and metal frame walls. This spacing provides adequate support for various wall finishes and contributes to the structural integrity and safety of the wall system.

Studs spaced at 600mm o.c. optimize load distribution and allow for efficient installation of insulation, as well as providing sufficient support for sheathing materials and other wall finishes. This spacing is commonly adopted for residential and smaller commercial buildings, ensuring that walls can bear the necessary loads without excessive deflection or failure.

The other choices represent spacings that are typically too large for standard construction practices. While it might be possible to achieve these spacings in specialized applications or with specially engineered materials, they are not applicable for conventional wood or metal stud framing as outlined in the typical building codes.
