Definitions for "Gatefold"
A type of fold in which the paper is folded toward its center to form four or more panels.
Edge of a page folded back on itself which when unfolded extends the size of the page providing more text or extending an illustration.
a magazine page that is larger than the other pages, but which is folded inward so that it fits into the magazine as the same size as the other pages (although it can be less than a page or even two or more pages); when the page is opened and unfolded outward, it swings out like a gate to reveal the full advertisement. In effect, it is a four-page sheet when unfolded, or an extra-wide ad. The space is sold at a premium. Also called a foldout.
