Are there "rules" on how high you should make a board and batten wall feature or is it just personal preference? I have a couple of rooms I'd like to do this in and could go different heights but don't want it to look odd if too low/high.
I really think it is a matter of personal preference. I always followed the rule of thumb that it should be standard chair rail height in a kitchen or dining room. (36-40") give or take an inch. If this is for living room or bedroom, it is very common now days to go up to 5 to 6 foot depending on the ceiling height. Standard ceilings are 8-9 feet, so the 5-6 foot wood look very nice. Again, it is your preference, your home, do it for your taste..:)
Apparently I am very old fashioned..lol..it looks like anything goes nowadays! Here are some examples of just how high people are taking it! So as I said..it is your preference that matters!
This I would estimate to be about 5-6 ft off the ground judging by the standard picture height of about 5 1/2-6 foot.
keep in mind bar stools like the ones shown are generally about 24" high, so this would be about a 48" height.
Who would run a chair rail THROUGH a light switch??? That's just silly! I would have taken it out too! I once moved into a home with the strangest walls I have ever seen! The former owners had left paneling...yes paneling at the top and sheet rocked the bottom half of the walls! If that wasn't bad enough, they stenciled the woodwork with vines!! I couldn't change that home fast enough!
