In English, DIN translates as 'German Institute for Standardisation'. Dr Porstmann's theory quickly became DIN approved, which is a standard in Germany meaning 'Deutsches Institut for Normung'. In the 1920's, Dr Porstmann of Germany published a document proposing a standard for sheet dimensions that would later change the world. The A4's size allows you to fit it inside a C4 envelope. It it used for everyday tasks like to-do lists, printing information from a computer, schedules and many other daily tasks. However, the most common page size in these countries is still 'Letter Size', along with other imperial page sizes.Ī4 size is the most common paper standard in the world. Many South American countries such as Mexico, Costa Rica, Chile, Venezuela and more, have officially taken on the A4 sheet dimensions standard. With the exception of the USA and Canada. Today, A4 is used by most countries around the world.
The standard is now used in the UK, India, Singapore, Germany, Europe, Japan and most other countries.
However, even though the ISO 216 standards were introduced in the early 20th century, it took more than 50 years for these paper dimensions to be recognised world wide. When Did A4 Size Become A Standard - ISO 216Ī4 paper became a standard in the late 1970's.
