Paper thickness is measured by grammage, which represents the weight of 1 square meter of paper. For example, the commonly used copy paper typically ranges from 80 to 100 grams. A standard business card weighs about 300 to 350 grams.
Each country has its unique base paper size. In China, there are three main paper sizes: 7971092mm, 8991194mm, and 841*1189mm. Regardless of the type of paper, it is cut into various sizes according to specific equal divisions. Therefore, when using paper, it is essential to consider how to cut it to achieve the maximum efficiency.
