Electronic tape measure

An electronic tape measure for measuring a body part comprises a housing with a tape outlet opening, a tape drum which is rotatably mounted about an axis of rotation in the housing, and a tape with length markings which is fastened, by an inner end, to the tape drum, can be wound onto the latter and can be guided out of the tape outlet opening. The axis of rotation defines an axial, a radial and an azimuthal direction. The tape measure also comprises the following modules: a read-out module which is configured to read out the markings; a data processing module which is connected to the read-out module and is configured to provide a measurement instruction for the user and to process a length measured value which has been read out; an input module which is connected to the data processing module and is configured to receive an input from the user; and a display module which is connected to the data processing module, is configured to display the measurement instruction and is arranged on the housing in a radial-azimuthal plane, wherein the display module comprises a screen.
