A method and system for sizing an earpiece include situating a calibration device proximate a user's ear. The user holds an image capture device so as to aim the image capture device at the user's ear. The user then touches and holds a random area of the touch screen display and releases the touch screen display to activate the image capture device and capture an image of the user's ear and the calibration device. The captured image is then analyzed and an earpiece size is determined based on the analysis of the image.
