In wall framing, a stud is typically spaced at 16 inches on center, which refers to measuring from the center of one stud to the center of the next. This spacing is a standard practice in residential and light commercial construction, as it provides the necessary support for drywall, sheathing, and other materials while accommodating structural integrity and load distribution.

Spacing studs at 16 inches on center allows for the efficient use of materials and consistent alignment for insulation installation, electrical wiring, and other components that may be added within the wall cavity. While 24 inches on center is also common in certain situations, such as for specific types of framing or insulation methods that might allow for less material, the 16-inch spacing remains the most widely used standard. Adjustments to this spacing may be made based on specific applications or codes, but generally speaking, 16 inches is the baseline measurement used in most residential framing.
