The ideal mounting height for a wall sconce is 66 to 78 inches above the floor. This height provides plenty of clearance, minimizing the likelihood of a passer-by accidentally bumping into the fixture.
The optimal mounting height for a wall sconce varies and depends on the intended purpose of the wall sconce. Sconces that are used primarily for task lighting are generally mounted lower on the wall, while sconces that are used for security purposes are mounted much higher. For applications that require a lower mounting height, the homeowner should choose a lighting fixture that rests relatively close the wall to prevent clearance issues.
