What Does “ISO 216” Mean?

ISO 216 is the international standard that defines paper sizes based on the A-series format. Each size is exactly half the previous one when folded parallel to its shorter side. This creates consistent, proportional sizing—perfect for scaling and printing documents.

Standard paper Sizes A0, A1, A2, A3, A4, A5, A6

To work out other paper sizes just remember the size of A4.
Standard paper sizes are really easy to work out all you do is half the longest edge to get the next size down, and to go up double the shortest edge
For example:  A4 page size is 210 x 297mm. Half of 297mm is 148mm.
Therefore A5 is 210 x 148mm.  
A3 is 420mm x 297mm, double 210 = 420

It's that simple

How do paper sizes work?

The international paper size standard ISO 216 was adopted in Europe in the 19th century and is now used in almost all countries throughout the world including South Africa. 
It is based on the German DIN 476 standard for paper sizes. ISO paper sizes are all based on a single aspect ratio of the square root of 2, or approximately 1:1.41421.

The advantage of basing a paper size on an aspect ratio of the square root of 2 is that when a sheet is folded, the length to width ratio does not change.

The A series is the most widely used standard for general printing and letterhead stationery.
The dimensions of the A series paper sizes are defined by the ISO 216.

The most common paper size is A4 (210 x 297mm) and the largest is A0, with an area of 1 square metre.
