What is the maximum allowed span of a 2x8 floor joist with specified characteristics in a bedroom?

8 ft 6 in
10 ft 8 in
12 ft 4 in
14 ft 0 in

The correct answer is: 10 ft 8 in

The maximum allowed span for a 2x8 floor joist in a bedroom depends on several factors, including the load the joist must support and the species of wood being used. In many building codes and guidelines, typical maximum spans for 2x8 joists vary based on these factors. For a 2x8 floor joist used in residential applications, such as in a bedroom where the loading is generally lighter compared to areas that bear heavier loads (like kitchens or living rooms), the maximum span often falls around 10 feet 8 inches. This distance provides sufficient structural integrity while still allowing for flexibility in design. Spanning beyond this length could compromise the joist's ability to adequately support the loads imposed on it, leading to potential sagging or structural failure. Therefore, adhering to the 10-foot 8-inch maximum span ensures safety, compliance with standard building practices, and adherence to local building codes, making this the appropriate choice. The other options represent spans that exceed the typical limits for a 2x8 joist in a bedroom setting, which would likely result in insufficient support and compliance issues.
