Paper Dimensions

​

The dimensions of the A series paper sizes, as defined by the ISO 216 standard, are given in the table below.
The diagram in both millimetres and inches (cm measurements can be obtained by dividing mm value by 10).
The A Series paper size chart, below on right, gives a visual representation of how the sizes relate to each other - for example A5 is half of A4 size paper and A2 is half of A1 size paper.
