Abstract

An electronic device and a method for automatically adjusting display ratio of user interface are provided. The electronic device includes storage device, a proximity sensor and a touch screen. The method includes the following blocks. The proximity sensor is controlled to measure a distance between the display screen and a user. The distance measured by the proximity sensor is obtained. A display ratio of the user interface is calculated according to the obtained distance and a algorithm which is pre-stored in the storage device. The display ratio of the user interface is adjusted using the calculated display ratio.
