A power operated tape measure enables measuring tape extension through a drive mechanism as well as measuring tape retraction through at least one of a drive mechanism and spring biasing on a tape reel. A tape cartridge assembly including an annular reel and a measuring tape wound onto the reel is positioned within a housing shell of the tape measure. A drive mechanism accomplishes tape extension out of the housing shell, and optionally, tape retraction into the housing shell by engaging with a surface of the measuring tape. An actuator initiates input on one or more switches that selectively control operation of the drive mechanism, and includes a lever arm for a user to make selections regarding tape extension and retraction. The actuator may be arranged such that lever arm motion in a forward direction enables tape extension and lever arm motion in a rearward direction enables tape retraction.
