foldout

A foldout is a noun and sometimes an adjective for something that is folded to fit into a smaller space and can be opened out when needed. In many cases, it refers to a page, map, chart, or picture printed on a sheet larger than the book or magazine itself, then folded to fit inside. When opened, it gives you a wider view than a normal page can.

This use is especially common in publishing. Books and magazines may include foldout maps, charts, diagrams, photos, or posters that need more room than a standard page allows. A travel guide might have a city map that opens across several panels, or a magazine might include a large poster folded neatly between regular pages.

The word is also used for things in everyday life that open from a compact form into a usable one. A foldout sofa, foldout bed, foldout table, or foldout chair is stored in less space and then opened when needed. In this sense, the idea is the same: something small or neatly packed becomes larger and more useful when opened.

Most often, foldout refers to a physical object rather than an abstract idea. In clear, everyday English, you will usually see it used for printed material and space-saving furniture or equipment. Overall, it describes something made to stay neatly folded until you open it and make full use of its larger shape.
