Poster Sizes And Types

A Paper Sizes

The dimensions of the A series paper sizes are defined by the ISO 216 international paper size standard. The A series was adopted in Europe in the 19th century, and is currently used all around the world, apart from in the USA and Canada. The most common paper size used in English speaking countries around the world is A4, which is 210mm x 297mm (8.27 inches x 11.7 inches). The largest sheet from the A series is the A0 size of paper. It has an area of 1m2, and the dimensions are 841mm x 1189mm. The A series uses an aspect ratio of 1:√2, and other sizes in the series are defined by folding the paper in half, parallel to its smaller sides. For example, cutting an A4 in half, will create an two A5 sheets, and so forth. Any size of brochure can be made using paper from the next larger size, for example A3 sheets are folded to make A4 brochures. The standard lengths and widths of the A series are rounded to the nearest millimetre.

Format Width x Height (mm) Width x Height (in)

B Paper Sizes

The dimensions of the B series paper sizes are defined by the ISO 216 international paper size standard. The B series is not as common as the A series. It was created to provide paper sizes that were not included in the A series. The B series uses an aspect ratio of 1:√2. The area of the B series paper sheets is the geometric mean of the A series sheets. For example, B1 is between A0 and A1 in size. While the B series is less common in office use, it is more regularly used in other special situations, such as posters, books, envelopes and passports.

US Paper Sizes

Loose Sizes
Paper sizes in North America do not follow a logical system like the ISO standard does. They have their own system that they follow. This means that scaling the paper sizes is more difficult. The US Letter paper size is the most popular size used throughout the US. It is also commonly used in Chile and the Philippines.

ANSI
The American National Standards Institute (ANSI) adopted ANSI/ASME Y14.1, which defined a series of paper sizes in 1996, based on the standard 8.5 inches x 11 inches (216mm x 279mm) Letter size, which was named ‘ANSI A’. This series is fairly similar to the ISO standard, in that if you cut a sheet in half, you will product two sheets of the next smaller size. Ledger/Tabloid is known as ‘ANSI B’. The most common and widely used size is ANSI A, also known as ‘Letter’.

Architectural Sizes
The Architectural series (ARCH) is used by architects in North America, and they prefer to use this series instead of ANSI, because the aspect ratios are ratios of smaller whole numbers (4:3 and 3:2). The ARCH series of paper sizes is defined in the ANSI/ASME Y14.1 standard. The ARCH sizes are commonly used by architects for their large format drawings, and form the basis for popular retail 'Small / Medium / Large' poster formats.

Billboard Sizes

A billboard (or a hoarding) is a large structure used for advertising, and is usually placed outdoors in areas where there is a lot of traffic, such as busy roads. Billboards are used to advertise products to passing pedestrians and drivers, and are very effective, due to their size and positioning in designated market areas. Billboards have many standard sizes, and the names of the billboards originate from the old days when posters were made up of a specific number of panels. Popular billboard sizes start from ‘1 Sheet’ which is 508mm x 762mm, and one of the largest is ‘96 Sheet’ which is 12192mm x 3048mm (40ft x 10ft). The largest standard sized billboard is known as a Bulletin, and is 48ft x 14ft.

There is some crossover with billboard sizes and both current and historic film poster sizes from the US and UK, with some sizes sharing alternate names across the advertising and cinema worlds, and some names sharing alternate sizes. '1 Sheet' in particular has at least 3 different sizes depending on industry and era.
