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 are many more options available for print within the ‘A’ paper series, which ranges 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 size chart

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.
