A gatefold cover or gatefold LP is a form of packaging for LP records that became popular in the mid-1960s. A gatefold cover, when folded, is the same size as a standard LP cover (i.e., a 12½-inch [32.7-centimetre] square). The larger gatefold cover provided a means of including artwork, liner notes, and/or song lyrics that would otherwise not fit on a standard record cover. It became famous as an extension of progressive rock, as the expansive, transient gatefolds by artists such as Roger Dean, H. R. Giger, or Hipgnosis became associated with concept albums.
