A measuring device comprises an outer casing and an inner drum mounted on a central hub of the casing. The drum has an innermost rim, an intermediate rim, and an outermost rim, each of the rims having a different diameter. The intermediate and innermost rims are arranged on one side of the drum while the outer rim is arranged on an opposite side of the drum. A tape is wound onto the intermediate rim on one side of the drum while a spring is wound inside the outer rim on the other side of the drum. This side-by-side arrangement of the tape and spring allows a lengthy tape, for example, 50 feet or more, to be quickly returned, compactly stored, and easily carried. A resilient shock-absorbing bumper is also provided around the periphery of the outer casing.
