Generally speaking, the font size is quite perpendicular to the rows and columns.

Generally, the font size is quite vertical and horizontal, yes. The reason for this is the following:

(1) "There are rows vertically and columns horizontally". This is an equally equidistant branch layout form, also known as "plum blossom lattice", which requires that the written words be evenly spaced, evenly spaced between rows, horizontally flat and vertical, and straight. Square paper, which is common in exam composition, is very beneficial to writing words.

(2) The characteristics of "vertical lines and horizontal rows" are clear lines, proper words, neat and clear, rigorous and generous, which are the most common in inscriptions and works written by seal script, official script and regular script. In terms of handling, the space is usually slightly smaller and the lines are slightly larger. In addition to applying "vertical and horizontal lines" in various works, today we often use it in writing official letters, announcements, exhibitions, wall newspapers and so on. So it should be the first time to learn the rules.

When we learn calligraphy, we usually write strokes first, then practice the structure, and then learn the composition. But most people who are impressed and judged always look at the whole-composition first, and then look at the part-structure and brush face. If they think the whole is not good enough, they won't look at the part. Composition is the first impression and total embodiment of calligraphy art appreciation, which can not be ignored. We should study and practice it hard.

We usually write or create calligraphy works in the form of sentences, paragraphs and articles. Therefore, we should not only write every word well, but also pay attention to the artistic treatment of the whole article. From the point of view that "writing" serves work and life, it is enough to write clearly, steadily, symmetrically and generously, which is easy to recognize and looks comfortable.
