One sheet

In the entertainment industry, a one-sheet or one sheet is a single document that summarizes a product for publicity and sales.

A one sheet is a specific size (typically 27" × 41" before 1985; 27" × 40" after 1985) of film poster advertising. Multiple one-sheets are used to assemble larger advertisements, which are referred to by their sheet count, including 24-sheetbillboards, and 30-sheet billboards. The term is also used as synonym for the poster artwork and the film poster itself.

Since a one-sheet is used in the official advertising for films, they are prized by both collectors of memorabilia for specific films and of film posters themselves. Film posters sold in general retail are in poster size, 24" × 36". Prior to 1985, the majority of film posters sent to cinemas were folded before mailing and, on rare occasions, they were instead rolled and shipped in tubes. While today there are several ways to eliminate these fold lines, many purists prefer film posters in their used condition.
