A CRT display screen of a word processor apparatus displays at least one line of characters. The number of characters in the line is variable, and the character size is automatically adjusted so that the lines fill the width of the screen regardless of the number of characters. The number of characters may be selected from several predetermined numbers such as 80, 96, 128 etc. Alternatively, the number of characters may be determined by the right margin position. In the latter case, when the right margin position is leftward of a predetermined character position, such as 80, the characters may be displayed in 80 character line format with blank spaces rightward of the right margin.
