Siding should be nailed to each stud or at what spacing?

Nailing siding to each stud at 16 inches on center (oc) is the standard practice because it provides optimal support and stability for the siding material. This spacing aligns with the typical layout of wall framing, where studs are usually spaced 16 inches apart. By nailing siding to the studs at this spacing, you ensure that the siding is securely fastened, reducing the risk of it becoming loose or damaged due to wind or impact. Additionally, this spacing allows for even weight distribution across the siding panels, helping to prevent sagging or warping over time.

Using a different spacing, such as 12 inches, may be excessively tight and not cost-effective, while 18 inches would not provide enough support, potentially compromising the integrity of the installation. Therefore, adhering to the 16-inch spacing standard ensures a balance between structural support and efficiency in siding installation.
