Calculate closet rod and shelf length for your wardrobe.
Hanging space is measured in linear inches of rod, and each garment type claims a predictable slice: about 1 inch for a shirt on a slim hanger, 1.25 for trousers, 2 for a dress or suit and 2.5 for a winter coat. Multiply your count by that figure and you have the single-rod run. Double-hanging halves it — two rods at roughly 40 in and 80 in above the floor fit in the same wall width and suit anything short — but it only works for shirts, folded trousers and jackets, since dresses and long coats need the full 60 to 70 in drop. The shelf above the rod matches the rod run, and it is worth planning as one number because the shelf is what carries the overflow the rod cannot.
Closet Rod Length
Rod length (in) = garments x inches per garment / tiers; tiers = 2 when double-hanging; garments per foot = 12 / inches per garment
About an inch on a slim velvet hanger and closer to 1.5 inches on a bulky plastic or wooden one — switching hanger type is the cheapest way to gain 30% more rod.
Roughly 40 in for the lower rod and 80 in for the upper, which leaves each tier about 38 in of clear drop. Below 40 in shirts brush the floor and above 84 in the top rod is out of easy reach.
No. Dresses, long coats and suit garment bags need 60-70 in of unbroken drop, so most closets end up with one double-hang section and one full-height section.
