A4 Size and ISO Paper Series

A4 paper belongs to the ISO 216 paper series, which includes a range of standardized paper sizes. The ISO system follows a simple rule where each size in the series is created by dividing the previous size into two equal parts parallel to the shorter side. Here are some of the standard sizes within the A series:

Paper Size Width (cm) Height (cm)
A0 84.1 118.9
A1 59.4 84.1
A2 42.0 59.4
A3 29.7 42.0
A4 21.0 29.7
A5 14.8 21.0
