Different paper sizes and their many usesPaper has so many different uses and there’s a size for every project


If you work in print marketing or any sort of marketing for that matter, we’d always recommend getting clued up on different paper sizes and formats you’ll potentially encounter.


In this guide we’re going to focus on ‘A’ and ‘B’ paper sizes.


Read on for our paper size charts and a breakdown of how each paper size is typically used.


A Paper Sizes


Let’s start with the most globally recognised paper size convention, A.


Formally adopted in Europe way back in the 19th century, the ‘A’ paper size system has since spread across the world. Aside from the USA and Canada, nearly every country uses this system now and it’s the most common standard business letter size used in English speaking countries.


You only have to glance at your home or office printer and you’ll most likely see A4 paper poking out of it. It’s the paper size most commonly known and used for everyday printing.


But there many more options available for print within the ‘A’ paper series, which goes from A0 through to A10.


Our charts below gives you a visual of the different A sizes available but, we’ve also provided a summary on how each paper size tends to be used.


 A paper sizes


A0 paper uses


The largest standardised paper size in the A range, A0 comes in at over 1 metre in height. That’s the equivalent of 16 A4 sheets of paper. This size is typically used for large signs or posters.


A1 paper uses


Like A0, A1 is typically used for signs, posters and window displays.


A2 paper uses


A2 is used for posters, notices, window displays and art prints.


A3 paper uses


A3 tends to be used for presentations, charts, posters and plans.


A4 paper uses


A4 is the most recognised ‘A’ paper size and is commonly used for everyday printing. A4 tends to be used to print business stationery letterheads.


A5 paper uses


A5 has many uses. This size is a popular choice for diaries & planners, books, invitations, flyers, booklets and more.


A6 paper uses


A6 paper is typically used for postcards, flyers, leaflets and save the dates


A7 paper uses


A7 tends to be used for large Post-it notes. It can also be practical for tickets, since you can print 8 of them on an A4 sheet.


A8 paper uses


A8 is the most popular size for business cards


A9 paper uses


A9 tends to be used for vouchers and tickets.


A10 paper uses


Being the smallest of the standardised A sizes, A10 is only ever really used for stamps or small vouchers.




B Papers Sizes


In addition to A sizes, naturally we have, (yes you guessed it) the B series. This paper series was introduced to provide a wider range of options.


We’ll mention at this point that there is also a C series which is a set of envelope sizes. We’re not going to include the C series in this article but we have a handy guide to envelope sizes right here.


The B series is that little bit bigger than it’s A counterpart. Again, we’ve given a quick overview of how each size is typically used.


B paper sizes follow the same pattern as A with B0 being the largest and dropping in size by half as you go from B0 to B10.


B aper sizes


B0 paper uses


This size is typically used for posters and enlarged photos.


B1 paper uses


B1 again tends to be used for posters and signs.


B2 paper uses


B2 is perfect for small posters.


B3 paper uses


This size is typically used for smaller posters and paintings.


B4 paper uses


B4 works well for little posters and notes.


B5 paper uses


B5 is a popular choice for menus, magazines and advertising flyers.


B6 paper uses


B6 tends to be used for booklets and flyers.


B7 paper uses


Small notebooks, menus and flyers – B7 is a good choice for these.


B8 paper uses


This size tends to be used for flyers and business cards.


B9 paper uses


One of the smallest B sizes, ideal for labels and small flyers.


B10 paper uses


The smallest B size is mainly used for vouchers and small cards.
