Paper Sizes

Published January 17, 2016 | By admin

Definition: ‘A’ size or ‘A’ series is a set of paper sizes established by the International Standards Organization (ISO) that ranges from A0 (the largest) to A7 (the smallest).

The size of the paper goes down as the number goes up, and each is half the size of the previous e.g. two A4 sheets make up an A3 piece and two A5 sheets make up an A4 sheet.
