Common Paper Sizes Explained


How to work out the size of print you need.

Here you can find information relating to the most commonly used paper sizes and how they relate to each other, to the uniformed person this can seem quite complex however if you read on you find that it is quite simple.

Most of the products that Print Stafford produce are on a set of paper called the A Series, which is standardised by ISO 216. The naming method of this group is simple and uses the letter A followed by a number. Most people are familiar with A4 as its the most common size house hold printers use and the size of most post your receive in the mail.

A4 as a rule of thumb is probably the most common size of paper used in the world.

These calculations and information are great know however if your short on time we have put reference tables together for you at the bottom of the page.

Well if you are going from A4 to A3 (The lower the number the larger the sheet) you double the size of the shortest edge. So for example we know an A4 sheet measures 210mm x 297mm making its short edge 210mm long. An A3 sheet measures 420mm x 297mm. When we move from an A4 to A3 we multiply the short edge by 2 up a size 210 x 2 = 420. This gives an A3 sheet the flat size equivalent of exactly 2 A4 sheets.

We hope we explained this ok, if not feel free to get in touch with your enquiry we would be more than happy to help.
