The use of the grid as an ordering system is the expression of a certain mental attitude inasmuch as it shows that the designer conceives his work in terms that are constructive and oriented to the future.

This is the expression of a professional ethos: the designer's work should have the clearly intelligible, objective, functional and aesthetic quality of mathematical thinking. Constructive design which is capable of analysis and reproduction can influence and enhance the taste of a society and the way it conceives forms and colours. Design which is objective, committed to the common weal, well composed and refined constitutes the basis of democratic behaviour. Constructivist design means the conversion of design laws into practical solutions. Work done systematically and in accordance with strict formal principles makes those demands for directness, intelligibility and the integration of all factors which are also vital in sociopolitical life.

Working with the grid system means submitting to laws of universal validity. The typographic grid: The grid divides a two-dimensional plane into smaller fields or a three-dimensional space into smaller compartments. The fields or compartments may be the same or different in size. The fields correspond in depth to a specific number of lines of text and the width of the fields is identical with the width of the columns. As a controlling system the grid makes it easier to give the surface or space a rational organization. Such a system of arrangement compels the designer to be honest in his use of design resources. It requires him to come to terms with the problem in hand and to analyse it. It fosters analytical thinking and gives the solution of the problem a logical and material basis. If the text is arranged systematically, the priorities stand out more clearly. By arranging the surfaces and spaces in the form of a grid the designer is favourably placed to dispose his texts, photographs and diagrams in conformity with objective and functional criteria.
This orderliness lends added credibility to the information and induces confidence.
