1. An electronic device comprising:
a flexible display including a display area visible from a front face of the electronic device, wherein a size of the display area is changeable, as at least part of the flexible display is moved, between a first size and a second size larger than the first size;
at least one processor comprising processing circuitry; and
memory storing instructions, that when executed by the at least one processor individually and/or collectively, cause the electronic device to:
control the flexible display to display at least a first portion of an image object and a text area including characters in a first screen corresponding to the display area of the first size, based on a reference position in the first screen,
based on a size of the display area visible from the front face being expanded and changed to the second size, determine a reference position of the display area of the second size by moving the reference position of the display area of the first size in a direction opposite to an expansion direction of the display area, and
control the flexible display to display, in a second screen corresponding to the display area of the second size, the image object moved relative the moved reference position and scaled-up based on the second size while maintaining an aspect ratio, and the characters rearranged based on the moved reference position and the scaled-up image.
