My calculations came up with 15 3 4 in.

Deck post footings size.

Deck footing size chart. Unless the deck requires engineering i refer to a beam span table as i design the framing. When the irc leaves us hanging we can often find an alternative rope to climb. The number of footings needed to support a deck beam is dictated by the beam s size.

The size and spacing of footings tie directly to the maximum spacing between posts of the beam they support. For aesthetic reasons most deck builders size them all based on the worst case loading. The evolution compression post base will make any deck footing look fantastic because the connection mechanism is completely hidden deep. A good size for a common backyard deck is a 10 or 12 diameter for the sonotube and a 20 base diameter.

This is between 3 and 14 in concrete. Of course you can get a 24 base size and it will spread weight over an even greater surface area. There is little material cost to a buried post footing. Diameter center footing size and table b3 calls for a 16 in.

Use added batter boards and string to mark rows of posts. Post spacing is going to depend on your design local building codes the size and length of your beams and the size of your posts. To calculate the load you should use 40lbs per square foot for live loads these are variable loads that are dynamic such as the weight of. Depending on how heavy and high your deck is your concrete footing underground may take 1 4 bags of concrete.

A comparison of the footing sizes i calculated for the example deck resting on 1500 psf soil in the sizing deck footings article and dca 6 table b3 shows an almost identical result. A larger beam can span a greater distance requiring fewer but larger footings. This is a permanent footing and is great for large or high decks that need very strong footings. In this case though i couldn t find a current source with a table that shows allowable tributary areas for various sizes and wood species of posts.

Step 3 fill the bottom of the hole with 6 inches of gravel and compact the gravel with a 2x4 or wood post. Post spacing should be even. Once you decide the distance measure from the house for the first row of boards. In order to determine the proper size for your footings you will need to establish how much total weight they are going to have to support and what kind of soil they are covering.

Step 2 dig footing holes about 6 inches deeper than required.
