Coat closet rods intended for coats or dresses should be 66 to 69 inches from the ground. When double-hanging a closet with two rods hung one above the other, the bottom rod should be hung 42 inches from the floor, while the upper rod should be hung 36 to 42 inches above the lower rod.
The rods should be hung 21 to 24 inches from the back wall of the closet to provide sufficient depth for hanging garments. Children’s closets may be double-hung with the lower rod beginning 29 inches from the floor. On the pole, each garment should be given 1 to 2 1/2 inches of space.
