Paper size standards govern the size of sheets of paper used as writing paper, stationery, cards, and for some printed documents.
The ISO 216 standard, which includes the commonly used A4 size, is the international standard for paper size. It is used everywhere except in North America and parts of Latin America, where North American paper sizes such as "Letter" and "Legal" are used. The international standard for envelopes is the C series of ISO 269.
The standard for drawing
sheet sizes is the A series. The basic size in this series is the A0 size
(1189 mm x 841 mm) which has an area of about 1-m3. The sides of every size in
the series are in the ratio Sq rt (2) = 1.414 : 1 and each size is half the area
of the next larger size.
