What is the general size of Chinese painting sketch?

Since ancient times, in China's calligraphy and painting market transactions, prices are generally based on the size of calligraphy and painting, such as "square feet". However, due to the various forms of China's paintings and calligraphy, there is a certain conversion relationship between "shape" and "square foot". Understanding and mastering the conversion between this relationship will be of great help to investing in painting and calligraphy.

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. Take Sichi Xuan as an example, its foot width is 68× 136 cm, and splitting or tripling is to divide it into three parts. Generally speaking, the whole four feet is eight square feet, and it is divided into four square feet, each square foot is about 33×33 cm.

Xuan paper calculation formula:

(1) length × width ×9= square feet (for example, four feet of whole paper1.36× 0.68m× 9 = 8.32 square feet. Basis: 1 m2 equals 9 square feet, and the calculation unit is meters. )

(2) Length × width /0. 1089= square feet (for example, four-foot paper1.36× 0.68m/0.1089 = 8.4 square feet). Basis: 33× 33cm = 1089cm2, in centimeters. )
