Standard Poster Size: What You Need to Know!

Most businesses know that producing high-quality posters as advertisements is a great way to promote their brand. It’s common knowledge that posters are an excellent way to get your message out there.

However, when making such promotional materials, things need clarification. After all, what exactly is standard poster size? What if your business has unique requirements? Which file format should you use? Do you need anything else? Let’s take a look at everything you need to know!

Standard Poster Sizes

If you want to print posters, you will find that not all poster sizes are created equal! Several different standard poster sizes are used throughout the world. You will find that the standard poster sizes will depend on several factors, such as the country in which you are printing the posters, the printer who will be printing the posters, and the intended audience.

So, let’s look at some of the most common standard poster sizes!


This is one of the most common standard poster sizes that you will find. A2 posters are typically used for exhibitions and art shows. This is because the poster is large enough to display various art pieces but not so large that it cannot be displayed on a wall. The size of this poster is 16.53 x 23.39 inches.


This is another widespread standard poster size. A3 posters are used for both exhibitions and as general poster sizes. The size of this poster is 11.69 x 16.53 inches.


This is one of the largest standard poster sizes and is typically used for exhibitions.The size of this poster is 23.39 x 33.11 inches.


This is another standard poster size used for exhibitions, but it is also an excellent option for newsletters or magazines. The size of this poster is 5.83 x 8.27 inches. 

When Is It Best To Use A Standard Poster Size?

Standard poster size is excellent for promoting a wide range of products and services. This is because a large poster will have a more significant visual impact on viewers than a small one.

For example, a real estate agent can increase the number of interested buyers by putting an image of a beautiful house on a large poster. This will likely have a more significant visual impact on viewers than just an image of the same house on a smaller poster. Standard poster size is best for events and campaigns you want people to remember.

People are more likely to notice and remember the information on a large poster than on a small one. Standard poster size is also great for high-impact marketing. You can use bright colors and bold fonts to get the most attention.

Which Dimensions Should be Your First Choice?

When designing posters, your first choices should be A3 (11.7 x 16.5 inches) and A4 (8.27 x 11.69 inches). These dimensions are widely used because they are the most cost-effective standard poster sizes. You can get these dimensions printed at a great price, given the size of your posters.

If you are designing a poster that has to travel across the country, a standard poster size like A2 or A1 will be your best choice. These standard poster sizes are more convenient for people traveling with your posters.

You can use smaller standard poster sizes if you design posters for a traveling exhibition. The smaller the posters, the easier it will be to transport them.

Which Dimensions Should You Stay Away From?

It would help if you avoided standard poster sizes that don’t fit well with your design. The poster might look off if the standard size doesn’t match your design. There are a few standard poster sizes that you should stay away from when designing your posters.


It is a small standard poster size that can be used when printing many copies. The smaller the poster size, the less area you have to play around with. The size of this poster is 2.9 x 4.1 inches.


This is a paper size that was used for newspaper printing decades ago. The newspaper printing industry has now moved on to other standard poster sizes, but there is still a chance that you might find a newspaper printed on this paper size. The size of this poster is 12.8 × 18.0 inches. 


This is the largest standard poster size that you can find. But most designers don’t use it because it is rather large for a poster. It is best suited for creating gallery-quality posters. The size of this poster is 33.11 x 46.81 inches!

What About Square Posters?

Square posters are almost the same as the standard poster sizes with an aspect ratio of 1:1. This means that the width and length of these posters are the same. The standard poster size closest to being a square poster is A5 (5.83 x 8.27 inches). It is an uncommon standard poster size, but it is almost a square poster.

You can use this for your posters if you want them to stand out. Square posters aren’t popular because they don’t fit easily into frames. So, you will have to make a custom frame to accommodate the square poster.

If you use a decorative frame, the edges of the poster might stick out past the frame, making it look messy.
