A centrefold generally refers to a newspaper, magazine, or brochure layout that uses a large two-page photograph or feature article in the central, or middle pages, which are designed to be opened and spread out flat. Historically, in some adult magazines, this term specifically referred to a full-page photograph of a nude or semi-nude woman.
