International paper sizes (ISO 216 / DIN 476) – a handy chart developed for you by Buzz Associates

Papers in the A series format have a 1:√2 aspect ratio – it keeps the ratio the same for each size after cutting a larger sheet in half.

Half a sheet of A4 = A5
Two sheets of A4 = A3
Four sheets of A4 = A2
Eight sheets of A4 = A1
Sixteen sheets of A4 - A0

International paper size chart

International paper sizes are governed by ISO 216 (A and B sheets, plus the German DIN 476 for the 'overformats' 2A0 and 4A0); ISO 217 (for the RA and SRA sheets) and ISO 269 (C series for envelopes, which is also part of DIN 678).

For background details about international paper sizes, please consult the sources listed right under the illustration.
