History of A4 Size

The A4 size was first developed in Germany by Dr. Walter Porstmann in the early 1920s. He proposed a new standard paper size that would be more efficient and cost-effective than the existing ones. His idea was to create a paper size that would allow for two sheets to be cut from a single sheet of the next larger size, thus reducing waste and production costs.

However, it wasn’t until the 1970s when the International Organization for Standardization (ISO) officially adopted the A4 size as an international standard. This happened because of the growing need for a standardized paper size for multinational corporations, businesses, and governments. Today, the A4 size has become the default size for various applications, such as letterheads, documents, and business forms.
