How far can a triple 2x12 beam span?
Simply so, how far can a 2x12 beam span?
When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.
Also, how far can a triple 2x6 beam span? A triple 2x6 beam over a span of 10' feet should be more than sufficient for normal deck loads.

In general terms, joists spaced 16 inches on center can span 1.5 times in feet their depth in inches. A 2x8 up to 12 feet; 2x10 to 15 feet and 2x12 to 18 feet. The larger the deck, the larger the joists.
