The typographic grid is a coherent page structure revealed and codified, made tangible and permanent. Its sole purpose is to aid the designer in the logical organization of information to improve both its accessibility and comprehension. Visually incongruous elements, whose only association is proximity on the page, can coexist within a well-conceived grid system.

Ideally, the nature and needs of the information will determine the grid’s form. It must be flexible enough to encompass diverse content, yet substantial enough to cohere its various parts: too loose and it risks diluting the intended message and confounding the reader; too rigid and it risks subduing the information and rendering it lifeless.
