When I was making very large wall hangings (painted quilts), I planned and drew them using three point perspective and always drew to scale. Some of my works were fourteen feet high, and were hung ten to twenty feet up. This made for some very interesting math problems.
I don't know if I would even attempt that kind of problem with a painting. The process is so different between the two types of art. You may want to check with someone who does murals on a large scale.
