What photo size do I need to print on a poster?

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 like brochures, business cards, 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.

There are 3 common poster sizes, which include an A2 (42.0 x 59.4 cm), an A3 (29.7 x 42.0 cm), and an A4 (21.0 x 29.7 cm) poster size. All these poster sizes are quite easily met when using a vector file from 99club, and you can print up to A3 size with 300dpi without worrying.

If you’re unfamiliar with what a vector is, it’s essentially a series of mathematical expressions or paths which 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 a poster is having a high-resolution image of at least 300dpi or by using a vector image.

Knowing Your Sizes and Pixels

When planning for a large format such as a poster you need to know what size you’ll need. Having 200 to 300 pixels per inch is a general rule of thumb for print. For 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 image(s) you find for your project is 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 or grid pattern of images on your poster. This may also help to convey your message in a very engaging way.
