The larger 12-foot side will have a post spacing of 6 feet at a minimum code requirement. That makes a total of eight posts that need to be installed on this average size deck. For aesthetic or symmetry reasons, more posts may be added.

Secondly, Should I use 4×4 or 6×6 deck posts?

How far can a 2×6 span without support?
A general rule of thumb for joist span is 1-1/2 times a board’s depth in feet, however, it’s not that simple. The distance a 2×6 can span is determined by the species, grade, location, use, load, and spacing. Based on building codes, a 2×6 can span anywhere from 2′-1” to 20′-8” depending on the affecting factors.
How deep should I dig for a deck post?

Does a deck Need Foundation?
Decks are supported by foundations, which transfer loads to the soil.

Deck posts connect the footing to the structure.
Is 6×6 better than 4×4?
6×6 or 4×6 will also give you less traction in specific conditions, than a 4×4. In snow/ice and other low traction situations, you have way less traction. And the exact reason I run a SINGLE rear wheel (not dually) rear on my pickup. Winter traction is FAR better with all the weight on 4 wheels instead of 6.
What accounts for 90% of all deck collapses?
About 90% of deck collapses occurred as a result of the separation of the deck ledger board from the house, allowing the deck to swing away from the house. It is very rare for deck floor joists to break mid-span. Many more injuries are the result of rail failure, rather than complete deck collapse.
Can 4×4 support a deck?
In the past, many decks were built with 4×4 support posts (also called structural posts). But these can bow seriously, even if a deck is only 3 feet off the ground. For that reason, we strongly recommend that you use 6x6s instead, even if your building department does not demand them.
How far can you span a 2×6 for a deck?
Decking made of 2x4s or 2x6s can span up to 24 inches. If you will run decking at an angle, you might need to put the joists closer together.
How far can you span a 2×6?

Can I use 2×6 for deck joists?
2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. … Most decks use 16″ on center spacing for joists. Most decking is not strong enough to support longer spans than 16″.
Why deck posts should not be set in concrete?
A deck post should always be placed on top of footing, not inside concrete because it can break. … Concrete tends to absorb moisture and wood expands when it gets wet, so these two factors combined will result in the wood breaking the concrete.
