How high is a chair rail usually hung on a wall?

Francisco Schonhardt: The height of chair rail is proportionate to ceiling height. Here's a helpful website:http://www.buzzle.com/articles/chair-rail-height.h...

Season Confalone: 38 inches, however if you already have chairs then measure the distance from the floor to the point where the back of the chair hits the wall and center it at that height. That is the purpose of chair rail after all, to keep the back of the chair from scarring the wall.

Clementina Collelo: Functional chair rail is installed 32 inches off the floor. It can be installed higher if preferred.

Danette Slotnick: I'm actually doing this in a hallway adjacent to a kitchen, so I suppose I'll place it at the height of the kitchen counter, which seems to be what you do when you're actually in the kitchen. Can I give myself "Best Answer" points for my own answer?
