Generally, wall sconces should be hung 72 inches from the floor. If the ceiling is very high, sconces can be hung higher for a dramatic effect or at the tops of pillars or beams to highlight the architectural element. If there are people taller than 6 feet in the house, the sconce should be hung high enough so the tallest person cannot look into it.

ADA certification is regulated by the Americans with Disabilities Act. ADA dictates that if a light fixture is mounted on the wall between 27 inches from the floor and 80 inches from the floor, it must not extend more than 4 inches from the wall. ADA enforces this regulation in public facilities for safety reasons.
