QuestionWhat is the standard height to mount a 55 tv on the wall?
Asked 5 years ago by Tal.
- Answer It really depends on personal preference and location availability. In general the center of the TV screen should be slightly higher the eye level where you will be watching TV. That being said, an easy way to experiment is to cut a piece of cardboard about the same size and move it around until you find a spot that fits well for you.
