To obtain paper sizes in centimetres, convert mm values to cm by dividing past 10 and in feet by dividing inch values by 12. More than units hither and sizes in pixels hither.

4A0 & 2A0 - The DIN 476 Oversize Formats

The paper sizes bigger than A0, 4A0 & 2A0, aren't formally defined by ISO 216 simply are commonly used for oversized paper. The origin of these formats is in the German DIN 476 standard, that was the original base document from which ISO 216 was derived. 2A0 is sometimes described as A00, still this naming convention is non used for 4A0.

A Series Newspaper Size Tolerances

ISO 216 specifies tolerances for the production of A serial paper sizes as follows:

±ane.v mm (0.06 in) for dimensions up to 150 mm (5.9 in)
±2 mm (0.08 in) for lengths in the range 150 to 600 mm (five.9 to 23.six in)
±three mm (0.12 in) for any dimension above 600 mm (23.vi in)

A Serial Paper Sizes Defined

The A series newspaper sizes are defined in ISO 216 by the following requirements:

The length divided by the width is 1.4142
The A0 size has an area of 1 foursquare metre.
Each subsequent size A(n) is defined as A(n-ane) cutting in half parallel to its shorter sides.
The standard length and width of each size is rounded to the nearest millimetre.

Note: For reference the terminal item is in that location because the root two aspect ratio doesn't always give a whole number.

International Usage

The A series paper sizes are at present in mutual use throughout the globe apart from in the The states, Canada and parts of Mexico. The A4 size has become the standard business letter size in English speaking countries such as Australia, New Zealand and the United kingdom, that formerly used British Purple sizes.

A3+ (Super A3)

A3 Plus, or Super A3 as it is sometimes known, is non an ISO 216 paper size. It has dimensions of 330mm x 483mm (13" 10 19"). This gives it an aspect ratio of 1:one.468 rather than the one:root 2 aspect ratio of the ISO series newspaper sizes. In actuality the A3+/Super A3 name is quite misleading every bit this paper size is known as B+ or Super B in the United states of america and is ANSI B with a ane" margin for print drain.
