The international paper size standard, ISO 216, defines the A series of paper sizes. The A series is based on a sheet of paper that is 1 meter by 1 meter, and each size is half the size of the previous size. The most common sizes in the A series are A4, A3, A5, and A6.

What is A4 Paper?

A4 paper has a fascinating origin and history. The “A” in A4 stands for “Annex,” and A4 paper was developed in the early 20th century by a German engineer named Walter Porstmann. He was looking for a way to standardize paper sizes and reduce paper waste. Porstmann proposed a system based on the square root of two, which made it possible to cut a larger sheet of paper into two smaller sheets while maintaining the same aspect ratio.

The A series of paper sizes was officially adopted by the International Organization for Standardization (ISO) in 1975, and it quickly became the most widely used paper size standard in the world.

A4 paper is slightly longer and narrower than the standard North American paper size, which is 8.5 inches by 11 inches. However, A4 paper is very similar in size to the Letter size paper when folded in half. A4 is also slightly smaller than the legal size paper used in North America, which measures 8.5 inches by 14 inches.
