Abstract: An electronic device and a method execute variable size function of menu icons in a user interface. The electronic device can change the variable menu icon size by an execution status of the menu icons corresponding to an application in the memory during a time period. During the time period, if one of the menu icons is not executed, the one of menu icon size reduces. If one of the menu icons is executed, the one of menu icon size magnifies. In addition, the reduction or the magnification of display size of the menu icons are limited to a maximum value.
