To obtain a display information layout apparatus which makes it possible to automatically alter the size of no dependent relation by displaying the display information on each inner region based on the size of a set lateral and longitudinal directions and the size of the lateral and longitudinal directions by area information.

First relation information specifies the relation of set width and set height between one inner set plate area and the other inner set plate region. For example, when the set height y2 of the inner set plate area 2b is cooperated with the set height y1 of the inner set plate area 1b, the set height y4 of the inner set plate area 4b is cooperated with the set height y3 of the inner set plate area 3b, and the set height y6 of the inner set plate area 6b is cooperated with the set height of the inner set plate area 5b, the first relative information so specifies 'inner set plate area 2b {relative size: area object name: inner set plate area 1b}' sets the set height of the inner set plate area 2b so as to coincide with the set height of the inner set plate area 1b.
