A gatefold cover or gatefold LP is a form of packaging for LP records. A gatefold cover, when folded, is the same size as a standard LP cover (i.e. a 12½ inch, or 32.7 centimetre, square). The larger gatefold cover provided a means of including artwork, liner notes, and/or song lyrics which would otherwise not have fit on a standard record cover.
Gatefold sleeves are frequently used when an album contained more than one record. Typically double albums would feature one disc in each half of the cover, with larger albums either placing multiple LPs in one or both sleeves or using larger gatefolds. An economical alternative is an extra capacity sleeve
