Lamps on bedside tables for example can have a scale and size that is proportionate to the height of the ceiling and the headboard or treatment on the bed wall. If your nightstand is 24” to 30” tall, Lamps should be at least 27” – 32” tall. Shorter nightstands, such as a low profile modern style that is only 18” TO 20” off the floor, call for a taller lamp to equal the visual proportion if the headboard is higher than 36” above the nightstand top.
