A portable electronic device includes a main body, a display and a distance measuring device. The distance measuring device includes a first distance measuring member and a second distance measuring member. The first distance measuring member includes a first signal emitting/receiving module and an arithmetic module. The second distance measuring member includes a second signal emitting/receiving module and a control module. The first signal emitting/receiving module is for receiving an alignment signal, emitting a measuring signal, and receiving a feedback of a measuring signal. The arithmetic module is for calculating the distance between the first distance measuring member and the second distance measuring member. The distance is displayed. The second signal emitting/receiving module is for emitting the alignment signal, receiving the measuring signal, and emitting the feedback of the measuring signal. The present disclosure further provides a distance measuring method for a device.
