A4 paper, the most common office supplies in our general life, actually hides a lot of strange mysteries that are not known. A4 paper looks ordinary, but in reality it contains rich history and culture. Let’s unravel the mystery of A4 paper along the way.
First, let’s look at the size of A4 paper. Its size is 210 mm x 297 mm, a standard size derived from the German DIN-4 paper standard, which dates back to 1922.

In this system, A4 paper belongs to A series of paper, where A1, A2, A3 and A4 respectively represent the size of the paper, A4 paper is the most common and frequently operated paper in this series.
In addition, the production process of A4 paper is also very particular. The production of A4 paper requires the operation of a special pulp, after the processing process, to make our common white flat paper. In the production process, the quality of the paper will also affect its use and end. For example, for documents that require high-definition printing, you need to operate high-quality, low-grayscale A4 paper.
However, under the seemingly popular surface of A4 paper, there are also some scene problems hidden. Because the production of A4 paper needs to consume a large number of wood costs, people’s excessive operation and extravagance of paper will also have a negative impact on the scene. In order to cover up the scene, at this moment, many enterprises and individuals are advocating environmental protection such as saving paper and dominating paper several times.
In short, A4 paper is of course the most common office supplies in our general life, but it is hidden behind the rich history, culture and environmental protection. We should take good care of ourselves and take good care of ourselves and do our best to protect the image of the earth.
