Let's also assume that the framing material is #2 southern pine (Douglas fir spans would be similar, but you should verify them). Most deck builders would typically support the free end of a deck this size on a beam made from two 2x12s supported on three posts set 7 feet 6 inches apart. (A beam made from 

However, all of this use and exposure to the elements eventually takes its toll, and some older decks begin to feel “bouncy,” meaning the deck's foundation needs shoring up.
