The weight of the deck and joist are transferred to the beams, which in turn, transfers the weight to the post. Joist The load from the deck is transferred directly to the joist. The Joist are supported by the beams and ledger. Joist spacing is determined by the type of wood used, and the size of the joist itself.
Determining the correct deck joist spacing and span is actually more complicated than you may think. Although building a deck seems strhtforward, there are a few important design factors to keep in mind. Your maximum joist span will depend on the wood species, joist spacing, size and whether the joists will be cantilevered.
The Joist Span indicates that 2x6s at 24 O.C. would be adequate for this span. For Beam 1, use a joist length of 13, 6 7 and a post spacing of 9. The Beam Table indicates that the beam may be two 2x10s or two 2x12s, depending on the wood used. For Beam 2, use a joist length of 7 and post spacing of 9.
Which is better for deck flooring: 2x6 or 1x6 deck boards? An other option if you have wider joist spacing is to add a joist between each one if possible, then
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. I am a first timer at this and would like all the help I can get.
The table makes it easier for deck builders to accurately size deck joists and for inspectors to check decks for adequate framing. I asked my local building official how he checks a deck plan to make sure the joist size and spacing combination will meet the code.
Joist Span. The maximum distance a deck joist can span between supports is determined by the joist's dimensions and species, as well as the spacing between joists.
The deck will be 20X16. There are 3 triple 2x6 beams that run the 20' length. the outer ones are 2' in and one at 8' in the middle ie. 6' is the maximum span The joists will be 2x6 joists and the 5/4 deck boards will be running at 45 degrees to the floor joists. So what kind of spacing should be used for the joists?
Framing tables for decks: joist and beam spans and sizes. Recommended or allowable joist and beam spans: this article explains typical spans for deck joists, deck beams, and deck flooring, giving both standard span tables and a quick "rule of thumb" that works pretty well.
Re: Deck Joist Size i use all 2x6's for joist max span is 7'. The strength of a deck is in the post and footings. It has nothing to do with joist span.

To increase the use of wood by assuring the broad regulatory acceptance of wood products, developing design tools and guidelines for wood construction, and influencing the development of public policies affecting the use and manufacture of wood products.
For a more rigid feel, it suggests reducing the maximum recommended joist spacing by 4 inches. Well, my 2x6 joists are spaced the maximum recommended 16 inches on-center on the new deck and 12 inches on-center on the refurbished one.
Changing joist span, depth, and spacing has a dramatic effect on deck strength. This table compares requirements at both minimum 50 psf and elevated 70 psf design loads. Cost estimates and framing layouts are provided for comparison only; actual costs will vary for different markets.
The proper deck joist span distance between supporting beams below the joists for your deck should be known before you start building and is needed to draft your deck plan. The spans of joists varies based upon several factors: joist size, spacing between joists, decking material and wood species.
