Original question by @[email protected]
I was putting up some wall decorations earlier today and was painstakingly realigning everything until it looked level to my eyes. It might be just a hair off, but if I don’t correct it, I’ll see the misalignment almost instantly and get bothered for the rest of time until I fix it. Has anyone investigated, or is there literature on the minimum perceptible angle from level to the naked eye?
I can tell you this much as an electrician: there’s “bubble level”, and there’s “building level”. Lots of buildings aren’t bubble level and you can either make it look right, or go by the bubble and look cockeyed.
Any home built by DR Horton or DSLD (American contractors) are like this.
The homes look fine, but nothing is “bubble level”. I had my attic ladder fall out of the ceiling due to some overweight things (and people) using it a lot to save things from some flood waters. We re-installed a new ladder, and made it “bubble level” which makes it now off from the ceiling itself. Now I’m working on filling the gaps between the ceiling and ladder frame in certain areas.
If you’re hanging some pictures, eye level is fine. If you’re doing anything else, please use a bubble.
