I still wood like to wood plank an accent wall in my dining room

They are truly beautiful and we are lucky to have one in our home that was already there when we got it. There are several Hometalker's here who have done this. Take a look through all of these options and see which one works for you the best (and you can ask them questions along the way) - https://www.hometalk.com/search/posts?filter=plank%20wall&r=0

The thickness of the wood is really irrelevant. What really matters though is that you use tongue in groove, or a similar edge. The reason is because all wood, no matter the species, expands and contracts with changing humidity. If you don’t use tongue in groove you will see gaps between the boards when the wood contracts.

I used inexpensive wood lath and stained it for a cool look for under $40. You can see it here: https://humboldtartdept.blogspot.com/2017/11/hall-bathroom-revisited.html?m=1

Hi! To find your dimensions, measure your wall from floor to ceiling in three places. Then do the same from side to side. Use your largest measurements to figure out your area.

(L x W). Round up and add 20% for waste.

In other words- If your wall measures 10’ 2” x 6’ 6” you would multiply 11 x 7 for 77 sq ft + 1.6 sq ft (20 %) rounded up = 79 sq ft of material.

As far as your wood goes, that depends on many factors. First is what look are you going for? Are you wanting the shiplap look, a barnwood look, etc.

The way it’s attached depends on what you are attaching the wood to. Is it framed and drywall, lathe & plaster, etc.

I hope that helps

😊
