A4, Foolscap, Letter & Legal Paper: The will to express thoughts and to propagate them has brought humans here today. Earlier, Stone age man used to write on cave walls and leaves, but when humans developed the brain, they felt the need to share knowledge not only to the paper in their lifetime but even beyond, to save the culture and tradition. This led to the invention of Paper. Paper has been around for centuries. Today, humans use paper for a lot of things. Paper is like our lifeline. Without writing, there would be no books, articles, legal documents, newspapers, decorative paintings, etc. Since its discovery and inception, we’ve adopted paper as a part of our daily life. Even boxes and carry materials and covers are made of paper.

Paper is the primary writing material since the medieval ages. Today we’re starting to change into digital writing, but still paper hosts the vast majority of our data, knowledge, and experience in handwritten or printed formats. For such an important thing, it is essential for us to know and understand how to use it efficiently. Earlier ages faced a lot of problems because of the differing paper sizes for each task and the papers from those times continue to cause trouble for us even today regarding storage and transportation.

Just think how useful it would be if all those old books you had we’re easily scannable into your PC and resizable without having to crop parts to maintain aspect ratio. How good it would be if all those books were of similar sizes and you could store them in a row on your bookshelf. How good it would be if all the legal documents were of similar sizes and you could keep them in a folder without having to think about either of them getting folded because they’re too big or moving around because they’re too small.

This led to the Standardization of Paper Sizes. Now Paper Standards introduce by ISO 216 are in use worldwide, and it has made all of our lives easier. But still, there are some countries which always follow the earlier traditional Standards and don’t accept ISO 216. But as they are some of the first world countries, it’s essential for us to know and study their paper sizes and compare them with ours. The most common paper sizes are the A4, Letter, Legal and Foolscap. Today, we’ll talk about these.
