A method for adjusting the screen size in televisions capable of optionally adjusting vertical and horizontal screen size without setting a number of screen size change modes for a variety of source images so that viewers can watch the screen with the desired size. The method includes the steps of determining whether a screen size change key input has been generated and when it has been determined that the screen size change key input was generated, determining whether a screen expansion key input or a screen contraction key input has been generated. When it has been determined that the screen expansion key input was generated, the method includes incrementing horizontal and vertical size data by one step, respectively, thereby expanding the screen size. When it has been determined that no screen expansion key input was generated, the method includes making a determination that a screen contraction key input has been generated, and decrementing the horizontal and vertical size data by one step, thereby reducing the screen size.
