The span of the joists the beam is supporting also determines the maximum deck beam span between support posts.

Pier block spacing for deck. Concrete footings, piers, and deck blocks are some options for deck foundations. Building a deck involves multiple carefully planned steps. These concrete foundation piers are generally installed about 8 to 10 feet apart, however, they can be closer together or further apart based on factors such as:

Subtract the foundation jog distance x from distance a to find the centerline of the beam at the left side of the deck. The distance between deck support posts depends on the type of wood species used and the size of the joist and beam. Measure the width of the deck from the stake in step 3, and drive a.

While decks just above the ground don't require posts, steps or railings, those that are several feet higher will. One thing unique about this floating deck is the type of footings. The maximum allowable spans are significantly longer with steel joists.
