In general terms joists spaced 16 inches on center can span 1 5 times in feet their depth in inches. The load that is placed on your deck is expressed in pounds per square foot psf and the total load or more appropriately the design load is comprised of the dead load and the live load. If there s wall board covered ceiling suspended from the underside of that floor the dead load increases to about 10 pounds per square foot. Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans.
