Hanging your wall sconces too low or too high can make them look awkward in your space. When considering what height should wall sconces be hung, personal preference does play a role, yet there are general guidelines you can follow. Installing wall sconces between 66-72 inches from the floor is standard, though exactly how high you hang them will depend on your ceiling height. Also, consider the distance between sconces as having them too close together might not help you to achieve the look you are going for.
