When Tschichold wrote Die Neue Typographie he set forth rules for standardization of practices relating to modern type usage. He condemned all typefaces except for sans-serif types, advocated standardized sizes of paper and set forth guidelines for establishing a typographic hierarchy when using type in design. While the text still has many relative uses today, Tschichold eventually returned to a classicist theory in which centered designs and roman typefaces were favored for blocks of copy.
