There’s a short answer to the question written in the title and that is answered in one word – Printing. Internationally, different paper sizes and types are made to fulfill efficiency in printing and make projects more attractive or clear.
Our previous article has shown you the different paper sizes and the common uses for each size. The A series for one is common and known to be available to most homes and offices. The paper sizes in this set started in the 19th century and spread around the world as the standard letter size for businesses.
The B series set, on the other hand, was made to give more options that don’t answer to A series. The only difference between A and B is the fact that B is only a little bit bigger. The C series meanwhile answers to needs that are related to letters or projects that should be fit for an envelope.
Knowing the standards
Do you know that there is an organization that develops and publishes international standards? It is called the ISO, short for International Organization for Standards, which makes standards for documents including guidelines, specifications, materials, processes, products and even paper.
