Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The backsheet has a physical variation along at least one axis, wherein said physical variation defines a first backsheet zone and a second backsheet zone, and at least one elastomeric element having at least one primary direction of stretch, said elastomeric element at least partially overlapping and joined to first and/or second backsheet zone, wherein a relaxed pathlength of said elastomeric element in the primary direction of stretch is less than a total pathlength of said backsheet in the region of overlap. The physical variation is a measurable difference as measured by a physical property selected from the group consisting of basis weight, thickness and density.
