Notching considerations
When choosing between 4×4 and 6×6 deck posts, notching is an important factor to consider. Notching involves cutting into the posts to accommodate headers, rim joists, and other deck components. While both post sizes can be notched, the larger size of a 6×6 post provides more room for the notching process, resulting in enhanced stability and support for the deck.
When to choose a 4×4:
- If your deck design requires minimal notching, a 4×4 post can be a suitable choice. However, it’s important to note that extensive notching on a 4×4 post can greatly weaken its structural integrity.
- In situations where local county inspection approves bolting headers to the posts instead of notching, a 4×4 post can be sufficient.
When to choose a 6×6:
- If your deck design requires significant notching or if you prefer the added stability and support that notching provides, a 6×6 post is a preferable option.
- Choosing a 6×6 post ensures that the entire beam holds the header of your deck, resulting in a secure connection and increased stability.
It’s worth mentioning that using a 4×4 post and bolting headers may not always meet local county inspection requirements, potentially compromising the stability of your deck. Therefore, if your project necessitates extensive notching or if you prioritize a stronger and more secure deck structure, opting for a 6×6 post is recommended.
By carefully considering the notching requirements of your deck design and choosing the appropriate post size, you can ensure that your deck is structurally sound and able to withstand the demands placed upon it.
