Paper Sizes

Understanding Paper Sizes

Paper sizes, their names and their origins are a fascinating subject that has developed over many years. If you are unsure that you are ordering the correct size, always give us a call on 0845 465 1027 and we'll be delighted to help.

Billboard Sizes

Billboards have been used since the early 19th century, following the invention of lithograhic printing, that allowed mass printing of large sheets. The earliest billboards were mostly to be found on the sides of buildings and are now frequently seen on the sides of roads, in bus shelters, in train stations and sometimes outside shops. Billboard paper sizes are described as "sheets" with a 4-sheet being 40"x60 and a 6-sheet being 1,200mm x 1,800mm. 

Size Width x Height (m) Width x Height (in)
4 Sheet 1.02 x 1.52 m 40 x 60 in
6 Sheet 1.20 x 1.80 m 47.24 x 70.87 in
12 Sheet 3.05 x 1.52 m 120 x 60 in
16 Sheet 2.03 x 3.05 m 80 x 120 in
32 Sheet 4.06 x 3.05 m 160 x 120 in
48 Sheet 6.10 x 3.05 m 240 x 120 in
64 Sheet 8.13 x 3.05 m 320 x 120 in
96 Sheet 12.19 x 3.05 m 480 x 120 in

A Sizes

The A series paper sizes, as defined by the ISO 216 standard, is part of an official metric standard.  It was set in 1975 and is based on a German standard originally from 1922, Deutsche Industrie Normenausschuß (DIN). The key feature of this paper size system is that A4 is half the size of A3, which in turn is half the size of A2 and so on up to A0. The A0 size is 1m2 of paper, so in the printing and publishing industries it makes it easy to scale, great for artwork and planning up print runs. So for A-series paper, smaller sizes are exactly half the previous paper size in every case, and importantly they are also exactly the same shape from one size to the next, with a width-to-height ratio of 1:1.41.

So an A4 page can be scaled up by 41% and all the artwork and text is the exact width and height to fill an A3 page. Equally, scaling A4 artwork down to 71% of its original size will see it fit perfectly on an A5 page with no stretching, squashing, or redesigning of artwork required. This “magic number” for paper aspect ratio, 1 to the square root of 2, was first suggested way back in 1786.

The A series paper sizes are now in used throughout the world apart from USA and Canada. The A4 size has also become the standard business letter size in English speaking countries including the UK, Australia and New Zealand. Historically, before metrication in the UK, British Imperial sizes were used. These were replaced with the ISO 216 standardisation which although easier to use and to understand does mean that we no longer have some of the rich names of paper sizes such as Albert, Duchess, Duke and Quarto. In Europe the A paper sizes were adopted as the formal standard in the mid 20th century and are now widely used.

Size Width x Height (mm) Width x Height (in)
4A0 1682 x 2378 mm 66.2 x 93.6 in
2A0 1189 x 1682 mm 46.8 x 66.2 in
A0 841 x 1189 mm 33.1 x 46.8 in
A1 594 x 841 mm 23.4 x 33.1 in
A2 420 x 594 mm 16.5 x 23.4 in
A3 297 x 420 mm 11.7 x 16.5 in
A4 210 x 297 mm 8.3 x 11.7 in
A5 148 x 210 mm 5.8 x 8.3 in
A6 105 x 148 mm 4.1 x 5.8 in
A7 74 x 105 mm 2.9 x 4.1 in
A8 52 x 74 mm 2.0 x 2.9 in
A9 37 x 52 mm 1.5 x 2.0 in

A Sized Paper Series Defined

The A series paper sizes are defined in ISO 216 by the following requirements:
a)  The length divided by the width is 1.4142
b)  The A0 size has an area of 1 square metre.
c)  Each subsequent size A(n) is defined as A(n-1) cut in half parallel to its shorter sides.
d) The standard length and width of each size is rounded to the nearest millimetre.

B Sizes

In addition to the A series, there is a less common, B series sized, sheets of paper. These were created to offer paper sizes that were not offered by the A series.
We stock snap frames in B2, B1 and B0 sizes:

Size Width x Height (mm) Width x Height (in)
B0 1,000 x 1,400 mm 39.4 x 55.1 in
B1 700 x 1,000 mm 27.6 x 39.4 in
B2 500 x 700mm 19.7 x 27.6 in

B Series Paper Sizes Definition

The B series paper sizes are defined in ISO 216 in the following way.
a)  The B series paper sizes were created in order to provide paper sizes that weren't covered by the A series, but also use an aspect ratio of 1:root2.
b)  B sizes are defined as size B(n) being the geometric mean of size A(n) and size A(n-1).
