Since ancient times, the price of calligraphy and painting is generally calculated by how many square feet. The size of calligraphy and painting refers to the size of writing core (the actual size before mounting, including the blank edge). Xuan paper is generally divided into three feet, four feet, five feet, six feet, eight feet and two feet, and now there are special formats. The ruler in calligraphy and painting calculation is different from the ruler measured now. It refers to the Lu Banchi invented by Luban, the originator of China carpenter. For example, take a four-foot rice paper as an example. Its size is 68× 137 cm. If it is cut three times or three times, it means that it is divided equally. Generally speaking, a four-foot whole paper is eight square feet, a four-foot divided paper is four square feet, and a four-square foot is also four square feet. What are flat feet? The so-called flat foot: 33.3cm×33.3cm, then the simplest calculation method is length (cm)× width (cm)× 0.0009. For example, the calculation method of a four-foot paper is: 137×68×0.0009=8.3844 (about 8 square feet), so there is no difference in the specifications of a four-foot paper.
