What is a type area at all? We use this term to define the area of a book page which distinguishes as a filled book page from the paper itself. In other words: The type area shows the lines of a book in a full book page. (Page numbers and other dead column titles are not added to the type area.)
A beautiful
type area is a pleasing relation between print
space and paper space. For assessing this relation, we will always
view a double page of a book – like we always see two pages of a
book side by side when reading the book. Basically the type area resp.
the blank paper borders should be formed in a way that the upper
border is smaller than the bottom border. At the same time the inner
borders of the two pages should not be wider than the relevant left or
right border of a book page.
There are various methods for deducing beautiful relations of
paper space and type area. Maybe you have heard about the item The
Golden Section
before, which is used here. A relation is perfect
when the type area's relation of width and height is the same as of
the paper's relation of width and height. You may e.g. define the type
area in a book page using a border relation of 2:3:5:8. Using a simple
DIN A5 page format and defining 16 mm for the inner border (back
margin), 24 mm for the upper border (capital margin), 40 mm for the
outer border and 64 mm for the bottom border (foot margin), you will
get a very esthetical relation of type area and paper size very soon.
You can surely imagine that deducing the golden section for distinct page formats has been a science in gone centuries. Publishing houses tried to distance themselves from competitors, but copying these found ideal type areas over centuries has led to our still used type areas of today.
But you will now get to know a method which leads you much faster to success than any other relation formulas or miraculous value tables could ever do. You will learn how to give your books of any page format beautiful type areas. We are talking about Division By Nine and Division by Twelve – which can be learned and used very easily.
