For heavy roofs or in areas with substantial snowfall or winds, call your local building department for code requirements. The tables below give maximum spans for rafters and beams. The figures are 

The cladding back span shall be no less than 1.5 times the deck overhang. If values are shown in brackets they represent the maximum allowable span if an overhang is used. for a side to be considered open, the full length of the side must be open. The values in the above table are for use with steel supports with a 

However, if the spacing is too wide, the patio cover's beams will bow under the weight of the joists and roof covering materials. The determining factor of post spacing is the allowable span of your beams: in other words, the maximum distance it can cover without support from posts. Allowable spans vary 

Blocks must be installed on patio stone or similar in order to maintain stability. Decks not attached to the house and less than 24” to the underside of the deck joists can be floating and installed on Dek Maximum overhang (cantilever) of any deck joist over a beam shall be no greater than the following: 2 x 6 deck joists: max

The joist size depends on the distance between supports, such as between the ledger board on the house and the supporting beam, or the distance between beams. See Table 4 and Figure 

Cantilevering deck joists allows you to build larger decks at lower cost. They are In addition to the limit on a cantilever's overhang, a deck must also be proportioned to balance weight on its cantilever. The maximum span for SYP PT 2x8s 12” o c is 14' 2”², so a girder at 14' 0” is close to the maximum.

If you are laying your deck on a non-concrete surface, such as grass or clay, lay the framing on patio slabs for additional stability. Deckboards can overhang the edge of the joists at the end or can be trimmed flush with the joints. A fascia board can The maximum recommended length of rails between posts is 1.8 metres.

For example, if a skirtboard is to be installed later, allow 3 4" on each end for that and another 3 4" on each end for the typical overhang. That's a total of 3" extra.
