Technical specifications

ISO 216 is an international standard for paper sizes, used around the world except in North America and parts of Latin America.

Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 "C" series is commonly listed alongside the A and B sizes.
