Abstract
An indicator (20) for a tape measure (10) is described. The indicator is marked with indicia (21) and arabic numerals (22) designating fractional increments between whole number measurements on the tape. In the preferred form the indicator is pivoted on the housing such as on pins 23 so the indicator can be folded adjacent the housing when not in use and can be unfolded and superimposed over the tape 12 when in use.
