A Brief History of A4 Paper
The A4 paper size belongs to the ISO 216 standard, which was developed in 1975. The A series of paper sizes is based upon a simple and logical system where the sizes are defined by dividing a sheet in half. The A0 size measures one square meter, and the subsequent sizes are obtained by cutting in half the previous size, producing a consistent element ratio, which is around 1: √ 2.
