The British (UK) Quad movie poster (30” x 40”) was issued on both paper stock and card stock. The British Quad poster is in the horizontal format and as such, the image was not a duplicate of the American one sheet poster. The Quad is the most common and most collectible of British movie posters. British Quad posters used to be issued folded but are now issued rolled.
Posters from Belgium measured 24" x 33" before 1939 but now normally 14 inches wide and the length from 19 to 22 inches. Can be horizontal or vertical. But the have a lot of variation in both the length and width. The smaller size usually has a space to theater name and show times, so it is also quite common to find them trimmed. Before 1945 they were approximately 12x17.
One Sheet size: approximately 24x33 - before 1939 they’re approx. 25x34
Large Size: approximately 33x67 - before WW2 and a rare size
Over the last few years, smaller distributors in Belgium have been using poster plates that were sent from the studios and printing them in Belgium. For example, if the film is coming from France, they may get the French plates for the Grande (47x63) and print it in Belgium to distribute. Then you would have a 47x63 French poster but it will have a Belgium printers tag. This saves money for the small distributor because he then does not have to pay for layout, drafting and artists to create the new posters and then the expense of having the plates made. So even though the printing cost may be slightly more, it eliminates all the pre-printing costs.
This means that you might see all types of sizes that are standard in other countries with a Belgium printer tag on it.
Posters are often known as an “Affiche”. Because of the bilingual language, many of the posters will be English, French and Dutch.
American One Sheet Poster globally known as the standard movie poster size and became the most popular among collectors. These posters were printed on a thin paper stock and were usually displayed in front of the theatre or in the lobby.
The 27” x 41” size became popular in the early 1900s, and remained so until the 1980s when the size was shortened to 27" X 40" (same as Australian one-sheets) but can vary slightly in length size dependent on the distributor and printer used. Many are now also double-sided for use in light boxes.
Many of the sexploitation movie posters of the 70s were printed by different printers and sizes varied from 25” x 37 up to 37” x 41”.
The One Sheet prior to 1980 was almost always found folded in eighths with one vertical fold and two horizontal folds, and after 1980 were sent to theatres rolled. The studios often printed a couple of different styles of posters for one film, one being what is known as an “Advance” poster issued before the release of a film to entice potential audiences to a showing, and the other one released to coincide with film’s release.
