Posts for a deck

I am building a 12' x 10' deck. I am pouring concrete columns, and using post brackets. The posts will be about 4' tall. There will be 9' between them. They will support a beam that the joists will sit on. Is it better to use a 4"x6" post, or a 4"x4" post? This deck will be located in Michigan. I only have access to brackets for a 4"x4" post. So would there be any benefit to using the bigger post? If I could get your oppinion, and or experiences with both that would be much appreciated.

Thank you

The 4 x 4's will work fine.

interesting, around here were only allowed to use 4x4's for handrail posts and fences. anything posts carrying a load must be 6x6

Good point --- you have to check local codes.

Around here 4 foot high decks can still be supported by 4-4's --- anything higher can not be. Though the talk is local code is going to change the height to 2 feet and 6x6 for anything higher.

Keeping in mind with 4x4 's they can not be notched for beam saddles --- only approved method of mechanical fastening is allowed.

hmm, yah, still we have to have 6x6 for all bearing, even if the beam is only 8" off the ground it has to be 6x6's. it makes for a lot less waste for us now when we cut posts, all those 2' offcuts now turn into what is sometimes 4 posts
