Book design Tschichold's rules

Tschichold's rules

Jan Tschichold (1902-1974) was one of the gr

eat book designers of the 20th century. He examined and measured many books from the medieval and renaissance periods trying to find "rules" for a pleasing design of book margins. He summarized his investigations in a book published in 1955. Tschichold recommended a 2:3:4:6 ratio among inner, top, outer, and bottom margins. For example:

Redesign a book according to Tschichold's rules
Pick any book. Measure the page size, text area, and margin widths.
Redesign the book's page so that page height and width, as well as the text area, are the same as that of the original book, but the margins satisfy Tschichold's rules.
