Calculation method of horizontal ruler for Xuan paper and calligraphy and painting works
Many people in the industry weigh four feet of paper (about eight square meters), and sometimes they just say eight square meters, so people who hear it are eager to insist that their paintings are eight feet of paper (eight feet of paper is equivalent to four four feet of paper, and the price has to be doubled). When they met another day, they took out a four-foot (about eight square feet) piece of paper and looked at it. The expert told the truth, but he didn't believe me, which made sense to you ... insisting that the buyer wanted it.
Grade I: 33.3cm× 33.3cm.
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), and the specifications of a four-foot paper are not equal.
So people in the industry usually calculate according to 8 square feet.
From ancient times to the present, China's valuation methods for calligraphy and painting transactions are various. In fact, the value of calligraphy and painting is not measured by the size of a ruler.
General differences between several paper specifications
Xuan paper is generally divided into four feet, five feet, six 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. Four-legged porch, with a scale of 68x 137 cm, is divided into three parts. Generally speaking, the whole four-legged porch is eight square feet, and the four-legged porch is four square feet. The vertical axis is dominated by straight painting, and the painting center is four feet three or four feet six. Generally, it is calculated by three square feet or one and a half square feet. If it exceeds the specification, it will be calculated according to the actual area. The banner is calculated by length, the width is less than one foot, and the actual area is more than one foot; Generally speaking, couplets are calculated by width, which is similar to banners, but the relationship between the number of couplets and the price is that the number of words is higher; The vertical length of the cross is about one foot, and the horizontal length is mostly less than four feet (except a few). The center of the painting is horizontal and vertical, and the horizontal length determines the size; Generally, the sector is calculated by one and a half feet, the sector is calculated by two feet, and the circular sector is calculated by diameter; The hand roll is calculated by the horizontal length, and the longer the horizontal length, the greater the level.
