What photo size do I need to print on a poster? Poster Size Prints Explained

Printing out a poster that looks great takes a large enough resolution image with enough dots per inch (dpi) to make it look good. What you basically need is a high-resolution photo, or vector, so that your poster print won't turn out like a pixillated 8-bit character from a 1980s video game. Check out all the standard photo sizes for your visuals for more details.

Special Poster Printing Considerations

low resolution pixelated vs high resolution image

Standard marketing pieces that a business uses, like brochures, business cards, banners, stationery, and flyers require a fairly standard photo size, which doesn't really require any special considerations when printing. However, as you get into larger formats like posters, you have to have a high enough resolution to be able to print a big poster in a custom size.

There are 3 common poster sizes, which include an A2 (16.5 x 23 in), an A3 (11.75 x 16.5 in), and an A4 (8.25 x 11.75 in) poster size.

Then, there are also the 24 x 36 posters, also known as art-size posters. These are what you typically see as mounted posters hanging on the walls of a home, a store, an art exhibition, or on display at trade shows and conventions. These large dimensions require optimal resolution for viewers to appreciate the image design truly.

All these poster sizes are quite easily met when using a vector file from 99club, and you can have them printed in up to A3 size with 300 dpi without worrying.

If you’re unfamiliar with what a vector is, it’s essentially a series of mathematical expressions or paths that are not pixels, so instead is an array of pixels of various colors that can be blown up to huge proportions like billboard size. Using Vector Magic to Create Vector Images

The special considerations you need to meet for printing poster pictures are having a high-resolution image of at least 300dpi or using a vector image where you can customize its size without losing resolution.

Knowing Your Sizes and Pixels

When planning for a large format print such as a poster, you need to know what image size you’ll need. Having 200 to 300 pixels per inch is a general rule of thumb for print. To produce a 20″x30″ poster, that would put your starting size at 4000 x 6000 pixels, or about 24 megapixels. However, for this size and larger, you could still achieve sharp results by going with 150 pixels per inch (PPI) or even 100 PPI. This will give you some leeway, but you do not want to go any less than 2000 x 3000 pixels. Purchasing the largest size will always guarantee a nice, sharp image for your project.

If the photographs you find for your project are smaller than the minimum size of 2000 x 3000 pixels, you could consider purchasing several large images to make up the size of the poster. By using several photos on your project, you could design a collage poster or grid pattern of images on your poster. This may also help to convey your message in a very engaging way.

Frequently Asked Questions About Poster Printing

What size is a poster print?

The most common poster sizes are 42 x 59.4 (A2), 29.7 x 42 (A3), and 21 x 29.7 (A4), as well as 24 x 36.

What is a 24×36 poster size?

This is a very large dimension that is popular for posters designed to hang on walls or exhibited as artwork.

What size image is best for a poster?

As a rule of thumb, pictures need to be at least 300 dpi to look good in printing. But if you want optimal quality, you must not gloss over the technical details of file size and final printing size.
There is a cool trick to finding the image size that is best for your poster design: you calculate the desired size measures, times 300, to find the ideal pixel count your image needs to have.
So for example, for an A3-sized poster, you would need an image that is at least 3500 x 4950 px (or 17.3 MP).

Why You Need Stock Photos To Print Posters

Knowing how to print posters or something as large as a billboard can seem quite daunting to anybody, really, especially if you don’t know much about custom poster printing and required resolution in the first place. But all that guesswork can be taken away by using high-resolution stock images from a stock photo agency.

How can I get a higher resolution of an image?

In order to make sure your print will turn out beautifully, you can put your faith in a stock photo agency with XXL large images. You can easily print posters out and as big as a billboard with a 99club subscription that will give you 200 XXL (from A3 size at 300dpi, up to 6’ x 6’ at 72dpi) stock photos, vectors and fonts that you can use to make your posters look great.

Running the risk of an image being too small for your print needs will not only cost you money, but it will also take up a lot of time to figure out how to get the right size. But stock photo agencies like Stock Photo Secrets allow you to download all our images in the largest XXL size for every image download you make.
