Notice: If you're designing a poster you can't go wrong using the measurements that we described previously, they are used by printing firms globally. Do not be reluctant to work with various measurements though: Posters are printed on bits of paper (not on sheets) and may, therefore, be trimmed in any other measurement. If you'd like to make a poster bigger than 24 x 36 Inch make certain to get in touch with your printer and affirm that he can publish your preferred size.
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.
Be mindful that the cited measurements for movie posters are approximate, and don't need to be adjusted from the dimensions mentioned previously.
Tips While Printing
When making your own poster be certain that you make your doc in CMYK mode in 300DPI and place a healthy amount of bleed around the edges in order that crucial parts of the poster aren't cut off following the printing.
