Explanation:
Detailed explanation-1: -Generally speaking, for a 16-foot span, you would need at least 2×6 joists spaced 12 inches on center. However, if you are using a heavier lumber such as a 2×8, you may be able to get away with spacing them 16 inches on center, as these joists can handle more weight than their 2×6 counterparts.
Detailed explanation-2: -For example, joists spaced 16 inches from the center of the joist next to it can span 1.5 times in feet the depth of their inches.
Detailed explanation-3: -The span for a 2x8 wood joist ranges between 16’ to 23’. The span for a 2x8 varies depending upon the species and grade of the wood as well as the loading conditions.
