Margin (typography)

In typography, a margin is the area between the main content of a page (the text-block) and the page edges. The margin helps to define where a line of text begins and ends. When a page is justified the text is spread out to be flush with the left and right margins. When two pages of content are combined next to each other (known as a two-page spread), the horizontal space between the two pages is known as the . (More generally, any space between columns of text is a gutter.) The top and bottom margins of a page are also called "head" and "foot", respectively. The term "margin" can also be used to describe the edge of internal content, such as the right or left edge of a column of text. Marks made in the margins are called marginalia.
