What is a poster, and why are poster sizes important?

A poster is a visual communication tool that is used to promote or bring awareness to an idea, event, or product. Posters are usually placed in public places where people can freely see them.  The best example is a movie poster that’s meant to promote an upcoming film. 

Posters are not only suitable for advertisements but are also great for decorating your indoor space. You can print out various items, including art, your favorite photos, or even a portrait of your family. Outside the home setting, posters can prove useful for educating the public and relaying announcements. 

It’s no surprise that posters can help focus people’s attention on issues that require deliberation. But, before you make a unique poster, you’ll need to find out the ideal size. This article will cover the best poster sizes for you. Posters are made out of paper: check the international paper size charts here or the ANSI Paper sizing here
