Paper Sizes Guide | A Sizes and Imperial

PRINTED IN-HOUSE WITH YOUR DESIGN

Choosing the right size

Put simply, the aspect ratio for A sizes is that two of one size will equate to one of the next size up.

  • 2 x A4 (Portrait) = A3
  • 2 x A3 (Portrait) = A2
  • And so on…

The larger the size of the paper, the smaller the number - A10 is the smallest and A0 size is the largest.

‘A’ sizes are commonly used across the globe and in 99% of our own printing. Here we will talk you through the dimensions, pixel size for the best print for posters, and dapple into other sizes we commonly use.

If you require much larger prints, like Movie Posters (27 x 40), Billboards, Hoarding Panel Coverage, or anything else, please contact us for more information. We have several state-of-the-art printers in-house all equipped to print in various formats, sizes, on multiple material types and in different inks.

‘A’ sizes are by far the most popular print size for posters and graphics, we also offer the following in standard dimensions, which we have detailed further down:

  • 20 x 30in
  • 30 x 40in
  • 40 x 60in

The ISO paper sizes are widely used in the printing industry. Below we've compiled a size chart graphic to visually show the difference between the A-sizes. Whilst many large format printers work in rolls as well as ISO paper sizes, they are still widely used when discussing posters, small signage, pavement signs and billboards.

A Paper Sizes in Pixels: Low & High Resolutions Explained

We use computers for all the purposes around us, especially now in the fields of Graphic Design, Photography and Website Design. Knowing your paper size dimensions is one thing, but it is even more critical for us to understand how those paper sizes link up today in our world of computers in pixel size, for the best quality visual effect and print.

Please note - Resolution doesn't necessarily dictate print quality. It all depends on the size, print media and product usage! So please do not be put off if your own artwork falls into the lower resolution category.

LOW RESOLUTION (@72dpi-90dpi)

Low Resolutions compromise of resolutions that are below 300 PPI but above 72 PPI. These devices are generally old devices when technology wasn’t this far or smaller devices like low-resolution mobile screens or low-resolution projectors, etc.

HIGH RESOLUTION (@300dpi)

High Resolutions are the ones that have a large number of Pixels Per Inch i.e. a whopping 1440 PPI to 2880 PPI. Such sizes and resolutions can theoretically either be seen on a very minute or small screen; with a whopping 4K panel or on largest screens with 16K or higher panels.

Print VS Digital

When sending a graphic to print, it is recommended to use a resolution of 300dpi, but depending on the quality of the image and the size you’re printing to, you can often get away with using a lower dpi. An A3 photographic image may look fine with a resolution of 150dpi.

When it comes to digital, people are often under the impression that the resolution should be set to 72dpi, but this is only a legacy value and it is image dimensions that are more important, because you are fitting a grid of pixels (your image) into a grid of pixels (the screen). A 500px x 500px image will always be 500px x 500px, no matter what the pixel density is.
