The spacing for floor joists is typically determined based on the load requirements, the type of material used, and the span of the joists. Common spacings are 16 inches on center for standard residential construction, but can vary to 12 or 24 inches depending on the design load and local building codes. It's important to consult engineering guidelines and local regulations to ensure proper support for the intended load. Additionally, factors such as flooring material and anticipated live loads should be considered when determining spacing.
