Closet math
Racks are sold by feel and returned by inches. Count what you actually own, answer two questions, and get the pieces whose rails cover the count. 67 hanging pieces are in the running; shelving and hampers sit this one out.
The fine print on the arithmetic: rail math assumes garments at rest, not compressed like a checked suitcase. Long pieces claim the top rail; a second rod only doubles the short half of the count. When two pieces tie, the one more people have rated goes first.
