The final format was going to have a ratio of 2:3 with the long side being 240mm and the short side 160mm.
A single page will contain a 5 point grid starting 20mm from the top and it will consist of 10 columns of 12mm width with a 5mm gap inbetween.
The content of each page can be placed within the type area of 6 columns, if it is text, or within the image area of 9 columns, if it is a picture. No content can be placed in the fold of the page or within the first or last 20mm of each page's height. The exception to this rule are pictures that cover entire pages.
The body text is written with the Book Antiqua font in a regular typeface. At 10 point size, it is exactly twice as big as the layout grid, which is also its line spacing.
Each paragraph is justified, while the last line is aligned left. Additionally, the optical margin alignment is activated in order to support a clean border on the right edge of the type and image area.
