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.
So, for an 8 foot long (2.44 m) deck, a Redwood joist of grade 2 lumber would need to be 2 x 6 (50.8 x 152.4 mm ). A larger joist size would be perfectly acceptable, whereas a smaller size would not. The 2 x 6 joist size is suitable for most types of grade 2 lumber at 8 feet (2.44 m) in length. A structure with a 10 foot (3.05 m) length, and joists set 12 inches (304.8 mm), apart would require using a floor joist size of 2 x 8 (50.8 x 203 mm).
