Poster printing

Posters are a cost-effective way of getting your message across, whether it’s in front of a crowd at a conference or around town as part of a marketing campaign.

One advantage of poster advertising is that your information can be placed at eye level in multiple places for maximum visibility, with costs far cheaper than advertising via television and radio.

Poster FAQs

What is a good dpi for a poster?

Resolution for a standard poster starts at around 124 dots per inch (dpi). The best dpi for a poster is 300dpi. However, the greater the viewing distance of the poster, the lower the dpi that is needed.

If the poster contains fine print or art work that people will want to inspect up close, the dpi needs to be kept high.

If you are unsure and need some advice, talk to our staff at Purely Digital and benefit from their years of experience in the printing trade.

How many pixels do I need for 24 x 36 posters?

The best quality posters are printed at 300dpi. But, as above, a lower dpi can be used if the poster is to be viewed from far away. This will not affect the overall quality of the poster as the distance will negate any possible ‘grainy’ appearance might occur by using a lower dpi.

What are the sizes of posters?

Posters can be any shape and size you want, within reason. However, a standard film poster used within cinemas measures around 24in x 36in (610mm x 360mm). A bus stop poster is larger, at 40in x 60in (1,016mm x 1,524mm).

The dimensions for a medium-sized poster are 18in x 24in (457mm × 610mm), while smaller posters are around 11in x 17in (279mm x 432mm).

What is the standard size of a poster presentation?

Conferences and other venues usually specify the size that your posters are required to be. However, many posters for presentations in academia and the business world use A1 and A0-sized poster.

Posters used in commercial advertising are often of the size A2.

Popular poster sizes

A2: 420x594mm/16.5×23.4in

A1: 594x841mm/23.4×33.1in

What kind of paper is used to print posters?

The weight of paper is measured in grams per square metre (gsm). A standard poster is printed on 170gsm with a silk finish.

Larger poster risk kinking and creasing; therefore, posters sized A1 and A0 are usually made from 200gsm satin.

If you are planning on creating larger posters, you may require synthetic materials in order to avoid kinking.
