A device and a method for determining length, area, and/or volume using a distance measuring device 10 includes a transmit unit 18 and a receive unit 20 in one housing, a keypad 28 for operating the measuring device 10, and an integrated computer 22 for evaluating measured data, and a display panel 26 for displaying the measurement results. The display panel 26 of the measuring device 10-after the operator selects a desired measurement mode by pressing just one button 32 on the keypad 28-uses an icon-based graphic display to indicate which of the individual measurements required to determine the desired measurement variable has yet to be carried out.
