Deck bearer and joist size question.

Just Starting Out

Deck bearer and joist size question.



I'm building a deck 8m x 3.5m and I'm unsure what size timber to use for the bearers and joists and also where to position my posts.


I have seen some previous posts on this topic where free sketch ups are done?


Any assistance would be greatly appreciated

Re: Top 10 most popular deck projects

Welcome to the Bunnings Workshop community @Bibes09. It's great to have you join us and many thanks for your question.


There are plenty of online tools to design your own deck. I've used your provided sizes to create a basic layout. This uses a traditional system of a 90 x 45mm joist over a 140 x 45mm bearer. You should find this guide useful if you need to build the deck in a limited height: How to build a low-level deck by @Adam_W.


I trust this will give you a starting point. You might like to create your own discussion so we can talk more about your project and questions.
