When building a deck, it is essential to consider the distance between the footings. This will depend on a variety of factors, such as the size of the deck, the type of beam used, and local building regulations. Generally, deck footings should be no more than 8 feet apart. However, some builders may opt to place them closer together for a more rigid frame. To determine the exact spacing for your deck, you can use an online calculator or consult your local building code.
The local building code will provide tables that indicate the allowed spacing between deck support posts. Additionally, it will tell you at what height you can build a deck with 4x4 support posts, which typically should not exceed 5 feet from the footing to the surface of the deck. When using a two-layer beam on 4x4 posts, there is a limit to how far apart you can space the support posts of your deck. For instance, a typical ground-level deck constructed of pressure-treated wood and securely connected with deck screws can support up to 50 pounds per square foot. If you need help determining the distance between the footings, enter the dimensions of your deck into a base and beam calculator. To locate the mounting position of each post on your deck's perimeter, use pegs and ropes.
You can also place two post anchors next to each other instead of using one 36-inch base. Keep in mind that online calculators are just an estimate and are not always accurate. When constructing your deck, it is important to consider the spacing between footings. Depending on the size of your deck, type of beam used, and local building codes, you may need to place your footings closer together or further apart. To ensure that your deck is safe and secure, consult your local building code and use an online calculator to determine the exact spacing for your deck.
