What is the maximum span of a 2x8 pressure treated joist?

The maximum span of a 2x8 pressure-treated joist typically ranges from 10 to 12 feet, depending on the load it must support and the spacing between joists. For standard residential floor loads, a span of 12 feet is common when joists are spaced 16 inches apart. It's essential to consult local building codes and consider factors such as wood species and specific load requirements for accurate calculations. Always ensure proper engineering guidelines are followed for safety and structural integrity.
