While the vertical placement of wall sconces can vary depending on individual taste, suggested placement is between 60 and 72 inches from the floor. They can be placed higher in rooms with taller ceilings.
Wall sconces are often used to highlight or accent specific features like a mirror or archway. When using them without accenting other items they should be placed from 8 to 10 feet apart in order to create a continuous band of light. Wall sconces can also be placed to accent windows, vases and side tables, or to provide a functional bright area in a room. Formality can be created by symmetric sconce placement, whereas asymmetrical placement lends a more casual air.
