Ellen Lupton, who urges us to think with type, proposes few examples : single-column, multi-column, horizontal anchor, modular. For her, « Grids belong to the technological framework of typography, from the concrete modularity of letterpress to the ubiquitous rulers, guides, and coordinates systems of graphic applications. (…) Avant-garde designers in the 1910s and the 1920s exposed the mechanical grid of letterpress, bringing it to the polemical surface of the page. In Switzerland after World War II, graphic designers built a total methodology around the typographic grid, hoping to construct with it a new and rational social order. »
