A program to calculate text areas according to Villard de Honnecourt and Jan Tschichold

Villard is a program that I wrote in the summer of 2005 inspired by two essays by Jan Tschichold, »Die Proportionen des Buches« (1955) and »Willkürfreie Maßverhältnisse der Buchseite und des Satzspiegels« (1962).[] Although I don’t especially sympathize with Tschichold II – the reactionary of the years after the Second World War – his fundamental thoughts on the layout of the page and the proportion of the text area are still very much worth reading.

Use of the program is quite simple: The first step is to chose the width and height of the page – either as a free proportion or, after fixing one dimension (horizontal or vertical), according to the following common proportions [1]:

golden section
1:squareroot of 2

In the second step the program allows you to calculate the relation between page and text area according to the three most important proportions described by Tschichold (precision of two decimals):

1. The first construction [2] goes back to the medieval architect Villard de Honnecourt (beginning of the 13th century). It divides the page horizontally and vertically into nine equal parts, the intersection of page and double-page diagonals thus dividing the page horizontally and vertically in the proportion of 1:3 to 2:3. It is more flexible than Tschichold’s constructions A und B, allowing a freer relation between page height (ph) and page width (pw).

2. Jan Tschichold’s »Construction A« [3]. The starting point is the intersection of the circle (radius: left page diagonal [x²+y²=ph²+pw²]) with the right page diagonal. Top and inside margin of the text area are identical. Outside margin is twice, bottom margin three times as large. The construction uses a ratio of 2 [width] to 3 [height].

3. Jan Tschichold’s »Construction B« [4]. The starting point is also the intersection of the circle (radius: left page diagonal [x²+y²=ph²+pw²]) with the right page diagonal. The upper margin is instead given by the intersections of page and double-page diagonals. The construction also uses a ratio of 2 [width] to 3 [height].

The program is just one file (ca. 2,8 MB), which you can copy in a directory of your choice. Start it with a doubleclick. It leaves no traces in the registry and does not use any temporary or ini-files. You can deinstall it by simply deleting it.
