The international standard paper sizes
The international standard paper sizes, also known as ISO paper sizes, are a set of standardized paper dimensions that have been adopted globally. The most commonly used size is A4, which measures 210mm by 297mm. Other popular sizes include A3 (297mm by 420mm), A5 (148mm by 210mm) and B4 (250mm by 353mm). These sizes are designed to allow for easy scaling and reproduction of documents across different devices and systems, ensuring consistent and reliable printing and copying. The ISO paper sizes are widely used in office and printing applications, as well as for personal and commercial printing needs.
