This is about the length of calligraphy. Depending on the situation, the writing is different, not limited to two formats. The format can be horizontal, vertical, fan-shaped, fan-shaped, and you can also draw a miniature version of nave, depending on the content. Generally, ancient poems and songs are suitable for vertical writing, while modern articles are suitable for horizontal writing.

Calligraphy spatial format
Due to the different writing contents and words, the writing length will be different, and the paper will also have different sizes and vertical and horizontal changes. Writing must be tailored to local conditions and carefully designed. There are various typesetting formats of calligraphy works. Here, the common writing formats are introduced as follows:
Nave: Also called full straight width, it is written vertically on full Xuan paper (uncut), which is a kind of calligraphy work with a large space.
Banner: Also called vertical, vertical and vertical axis, it is also a calligraphy work written vertically, which is narrower than that of nave. Generally, the whole rice paper is vertically cut in half or wider than half.
Sector: There are two types: round fan and folding fan. The top of the circular fan is better, and the folding fan is unique in annular radial shape, and the row spacing width is different from top to bottom, and each row is inclined around the fan axis. The written sentences should be arranged according to the shape, showing the characteristics of folding fans.
Album and picture frame: a small calligraphy work one foot square, which is framed after writing and usually hung in a picture frame.
Long scroll, banner, banner: It is also a common writing format. Contrary to banners, banners are written horizontally with paper, and all kinds of books can be written, and the word order is generally from right to left. When writing Spring Festival couplets, I often write a few words on the red paper at the gate, which echoes the upper and lower couplets and is called cross-string.
Couplet: Also called "Right". Written by two rectangular strips of paper, together they are called a picture, with the upper part on the right and the lower part on the left. The number of words in couplets is not specified, but the number of words in upper and lower couplets should be the same, and attention should be paid to antithesis and neatness.
