( Definition taken from Wikipedia) Portrait mode and landscape mode refer to the orientation of text (and pictures) on a printed page. (The paper must be a rectangle, however in practice square sheets are hardly ever used.) In portrait mode the text is printed on the paper such that the reader will turn the long side of the paper vertical and the short side horizontal. In landscape mode on the other hand, the long side is horizontal, and the short side vertical (like most landscape paintings).

Portrait mode and landscape mode refer to the orientation of text (and pictures) on a printed page. (The paper must be a rectangle, however in practice square sheets are hardly ever used.)
