The difference between A4 and A3 size paper is in their dimensions. In fact, if you consider the space available, A3 paper has double the area of A4 paper. Now, before discussing them, have you heard about ISO1 216? It is the International Standard for Paper Sizes that is used for letters and documents (and also magazines) in most parts of the world. It describes in detail all sizes included in the A series and B series of papers. It is the A series that we are interested in this article.

Knowing the basis of ISO 216 will enable one to understand the difference between A4 and A3 size paper.
The system of ISO 216 has been designed in such a manner that the aspect ratio is same for all paper sizes, whether they are A, B or C. The aspect ratio is unique and maintained at one to square root of 2. If this does not mean anything to you, just remember that A0, turns into A1 when halved along the shorter side, and A1 becomes A2 when halved along the shorter side. So in A series, the number after A corresponds to how many times it has been halved starting from 1 square meter paper, which is A0.
