Movie Poster Sizes
There are just two distinct measurements for film posters the movie business has standardized. Both are usually in portrait format:
One Sheet - that is generally 27" x 40" Inches in dimension (686 x 1016 mm). Commonly utilized in theaters for advertising movies.
Bus stop (or subway poster) - are usually 40" x 60" Inches in dimension.
The “One-Sheet" dimension is used at the official advertisements for movies.
Both are usually printed on newspaper stock and generally rolled for aesthetic motives.
