How far apart must trusses be spaced in a residential structure for proper support?

In residential construction, trusses are typically spaced 16 inches apart on center for proper support and structural integrity. This spacing allows for adequate load distribution across the trusses and supports the weight of the roof and any additional loads such as snow, wind, or equipment. Moreover, at this spacing, it facilitates the installation of standard-sized insulation batts and wall materials, promoting energy efficiency and minimizing gaps.

While other spacings are sometimes seen in specific situations or types of construction, the 16-inch spacing has become a standard practice in residential building due to its balance of strength and efficiency in materials and labor. Adhering to this standard helps ensure compliance with building codes and the longevity of the structure.
