In the field of book design, proportions of pages, type areas (print spaces), and margins of medieval books have been analyzed by scholars, and several principles known as canons of page construction have been described by them to represent the ways in which these books may have been designed.
The notion of canons, or laws of form, of book page construction was popularized by Jan Tschichold in the mid to late twentieth century, based on the work of J. A. van de Graaf and Raúl M. Rosarivo, Hans Kayser, and others.[1] Kayser's 1946 Ein harmonikaler Teilungskanon[2] had earlier used the term canon in this connection.
Though largely forgotten today, methods and rules upon which it is impossible to improve have been developed for centuries. To produce perfect books these rules have to be brought to life and applied.
— Jan Tschichold [3]
Typographers and book designers apply these principles to this very day, with variations related to the availabilty of standardized paper sizes, and the diverse types of commercially printed books. [4]
Van de Graaf canon

The Van de Graaf canon is a historical reconstruction of a method that may have been used in book design to divide a page in pleasing proportions.[5] This canon is also known as the "secret canon" used in many medieval manuscripts and incunabula.
The geometrical solution of the construction of van de Graaf's canon, which works for any page width:height ratio, enables the book designer to position the text body in a specific area of the page, in such a manner that the proportions are maintained, while creating pleasing and functional margins of size 1/9 and 2/9 of the page size.[6] The resulting inside margin is one-half of the outside margin, and of proportions 2:3:4:6 (inner:top:outer:bottom) when the page proportion is 2:3 (more generally 1:R:2:2R for page proportion 1:R). This method was discovered by van de Graaf, and used by Tschichold and other contemporary designers; they speculate that it may be older.[7]
The page proportions vary, but most commonly used is the 2:3 proportion. Tschichold writes "For purposes of better comparison I have based his figure on a page proportion of 2:3, which van de Graaf does not use."[8]. In this canon the text area and page size are of same proportions, and the height of the text area equals the page width.
This canon was popularized by Jan Tschichold in his book The Form of the Book.
Golden canon

Tschichold's "golden canon of page construction"[1] is based on simple integer ratios, equivalent to Rosarivo's "typographical divine proportion."[10]
Interpretation of Rosarivo
According to Fabián Carreras, Raúl Rosarivo, in his Divina proporción tipográfica ("Typographical Divine Proportion"), first published in 1947, analyzed Renaissance books with the help of compass and ruler and concluded that Gutenberg, Peter Schoeffer, Nicolaus Jenson, and others, applied the golden canon of page construction in their works.[11] According to Rosarivo himself, his work and assertion that Gutenberg used the "golden number" 2:3, or "secret number" as he called it, to establish the harmonic relationships between the diverse parts of a work,[12] was analyzed by experts at the Gutenberg Museum and re-published in the Gutenberg Jahrbuch, its official magazine.[13] Ros Vicente points out that Rosarivo "demonstrates that Gutenberg had a module different from the well-known one of Luca Paccioli" (the golden ratio).[13]
Tschichold also interprets Rosarivo's golden number as 2:3, saying "In figure 5 the height of the type area equals the width of the page: using a page proportion of 2:3, a condition for this canon, we get one-ninth of the paper width for the inner margin, two-ninths for the outer or fore-edge margin, one-ninth of the paper height for the top, and two-ninths for the bottom margin. Type area and paper size are of equal proportions. ... What I uncovered as the canon of the manuscript writers, Raul Rosarivo proved to have been Gutenberg's canon as well. He finds the size and position of the type area by dividing the page diagonal into ninths." [14] The figures he refers to are reproduced in combination here.
John Man's interpretation of Gutenberg
Historian John Man suggests that Gutenberg's Bible page was based on the golden section shape, based on the irrational number 0.618 (or a ratio of 5:8) and that the printed area also had that shape.[15] He quotes the dimensions of Gutenberg's half-folio Bible page as 30.7 x 44.5 cm, a ratio of 1:1.45, close to Rosarivo's golden 2:3 (1.5).
Tschichold and the golden section
Building on Rosarivo's work, contemporary experts in book design such as Jan Tschichold and Richard Hendel, assert as well that the page proportion of the golden section (21:34), has been used in book design, in manuscripts, and incunabula, mostly in those produced between 1550 and 1770. Hendel writes that since Gutenberg's time, books have been most often printed in an upright position, that conform loosely, if not precisely, to the golden ratio.[16]
![](http://upload.wikimedia.org/wikipedia/commons/thumb/a/a1/Golden_section_page_Tschichold.svg/220px-Golden_section_page_Tschichold.svg.png)
These page proportions based on the golden section or golden ratio, are usually described through its convergents such as 2:3, 5:8, and 21:34.
Tschichold says that common ratios for page proportion used in book design include as 2:3, 1:√3, and the golden section. The image with circular arcs depicts the proportions in a medieval manuscript, that according to Tschichold feature a "Page proportion 2:3. Margin proportions 1:1:2:3. Text area in accord with the Golden Section. The lower outer corner of the text area is fixed by a diagonal as well."[17] By accord with the golden section, he does not mean exactly equal to, which would conflict with the stated proportions.
Tschichold refers to a construction equivalent to van de Graaf's or Rosarivo's with a 2:3 page ratio as "the Golden Canon of book page construction as it was used during late Gothic times by the finest of scribes." For the canon with the arc construction, which yields a text area ratio closer to the golden ratio, he says "I abstracted from manuscripts that are older yet. While beautiful, it would hardly be useful today."[18]
Of the different page proportions that such a canon can be applied to, he says "Book pages come in many proportions, i.e. relationships between width and height. Everybody knows, at least from hearsay, the proportion of the Golden Section, exactly 1:1.618. A ratio of 5:8 is no more than an approximation of the Golden Section. It would be difficult to maintain the same opinion about a ratio of 2:3." [19]
And he expresses a preference for certain ratios over others: "The geometrically definable irrational page proportions like 1:1.618 (Golden Section), 1:√2, 1:√3, 1:√5, 1:1.538, and the simple rational proportions of 1:2, 2:3, 5:8 and 5:9 I call clear, intentional and definite. All others are unclear and accidental ratios. The difference between a clear and an unclear ratio, though frequently slight, is noticeable. ... Many books show none of the clear proportions, but accidental ones."[20]
John Man's quoted Gutenberg page sizes are in a proportion not very close to the golden ratio,[15] but Rosarivo's or van de Graaf's construction is applied by Tschichold to make a pleasing text area on pages of arbitrary proportions, even such accidental ones.
Current applications
Richard Hendel, associate director of the University of North Carolina Press, describes book design as craft with its own traditions and a relative small body of accepted rules. [21] The dust cover of his book, On Book Design, features the Van de Graaf canon.
German typographer Paul Renner, creator of the Futura typeface, described his views about page proportions, according to Christopher Burke:[22]
Renner still championed the traditional proportions of margins, with the largest at the bottom of a page, 'because we hold the book by the lower margin when we take it in the hand and read it'. This indicates that he envisioned a small book, perhaps a novel, as his imagined model. Yet he struck a pragmatic note by adding that the traditional rule for margin proportions cannot be followed as a doctrine: for example, wide margins for pocket books would be counter-productive. Similarly, he refuted the notion that the type area must have the same proportions as the page: he preferred to trust visual judgment in assessing the placement of the type area on the page, instead of following a pre-determined doctrine.

While the geometric design itself is unquestionably that generated from the Pythagorian monochord, Kayser does not convince the reader that Villard understood its musical basis. Kayser apparently worked from photographs of the original folios, and the significance of Kayser's claim may be summarized in his own admission (p. 30) that Villard's geometry does not match that of the Pythagorean design when correctly drawn."
