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 is the size of an A1 poster?

An A1 poster is 594mm x 841mm, or 23.4in x 33.1in.

The following table lists standard poster sizes in millimetres and inches:

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

A0: 841×1,189mm/33.1×46.8in

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.

What size of print run can you offer?

Because we use a combination of digital printing and offset printing, for poster printing we can technically offer an unlimited-size print run and keep the costs relatively low. We generally recommend offset printing for large volumes, but we’re happy to discuss your specific requirements and advise you on which printing method will be best.

How long does a normal poster print run take?

We can usually turn around an order of posters within 24 hours.

What do i need to think about when designing a poster?

With all great posters, you can be sure that a lot of thought has gone into every element of the design to make sure they have that attention-grabbing impact. Here are some things you should bear in mind when designing your own poster.

Choose one great image to focus on

A good poster begins with a good idea. And you’re aiming to perfectly encapsulate that idea with one simple but effective image. This will need to be of a high enough resolution to appear sharp and crisp on a large poster (at least 300 pixels per inch).

If you don’t have an image that you’ve produced yourself (and therefore own the rights to), there are lots of websites that provide stock images. Sites like Shutterstock and Getty Images ask for payment, while others such as Freepik, Pexels and Pixabay offer images for free.

Be sparing with fonts

A few fonts, used well, can have a lot of visual impact. Employ too many and your poster can look messy and be hard to read, especially at a distance and at a glance. When you use a combination of fonts, make sure they complement each other and provide an appealing contrast.

Use grids to help with layout

Having a grid layout dictate your design will result in a neat, professional-looking poster. This article explains the grid design and how to employ it to its fullest potential.

Limit your colour palette

Like with fonts, your choice of colours is almost endless. But restrict your colour palette to two or three options and your poster will be the better for it. Using too many colours gives the design a chaotic, slapdash feel that will repel the eye rather than draw it. And avoid combinations of very bright colours.

Create contrast between background and text

There should be high contrast between the poster’s background and the text. A light-coloured background and dark-coloured text will always work, and the most important part of the poster should stand out and have the greatest contrast with the background.

What makes a poster “high-quality”?

To get a poster of the highest quality, you’ll need to consider the following:

Resolution

The more dots that make up an image, the higher the resolution. The best-quality posters are printed at 300 dots per inch (dpi).

Colour and black

The RGB colour model has a wider range of colours than CMYK. However, it’s far better to work in CMYK as you can get a more accurate representation on screen of how the colours will appear when printed. Blacks can be troublesome if set up in RGB, so setting them up in 100% black is recommended. But rest assured we’re always here to offer advice—just give us a call.

Paper

When we talk about the ‘weight’ of paper stock, we generally mean its thickness and stiffness. Weight is measured in grams per square metre (GSM), and it tends to be the case that the heavier the paper, the better quality it is. You also need to think about whether you want a glossy finish, for example.

Not all paper stock is appropriate for posters and so we’d advise you to speak to us about your exact needs.

Digital file size

The better the quality (and the larger the size) of the digital file you provide for print, the better the quality of your poster. Files in PDF or TIFF format set to 300dpi resolution with no compression are best.
