DIN 476 (paper size standards)

DIN 476 is a standard developed in Germany that defines a series of paper sizes based on the A and B series. The most common size is A4, which measures 210 mm by 297 mm. The sizes are designed to be proportional, meaning if you divide a sheet in half, you retain the same aspect ratio. This allows for easy scaling and organization in printing and documentation. The system streamlines paper usage in offices and schools globally, enhancing efficiency and compatibility across various applications. It has become the basis for standardized paper sizes in many countries.
