A southern pine (2) 2x12 beam can span 8 feet when supporting joists spanning a maximum of 14 feet, and it can cantilever 2 feet beyond the posts on each side. With the allowable cantilever of the joists, this beam would support a deck 12 feet by 17 1/2 feet.
My question is if it is ok to use 2x6's as my joists for the floor. The span to the beams will be at 7ft and I will be going 16 on center spacing.
