What's the average height of wainscoting?
While there's some styles that call for higher or lower heights, you can bank on one general rule if you need a starting point. Measure a third of the way up your walls and that's where the top of your wainscoting should land. For example, if your dining room has 9 foot walls your wainscoting should be 3 feet tall. It's common for average height to fall between 36 and 42 inches.
