What is the maximum span for 2X8 floor joists on 12 oc?

The maximum span for 2x8 floor joists spaced 12 inches on center (oc) typically ranges from 12 to 14 feet, depending on the wood species and grade used. For example, Southern Yellow Pine can span up to 14 feet, while other species may have shorter maximum spans. Always consult the local building codes or a structural engineer for precise requirements and safety considerations.
