The internal frame structure of a font is the basic factor that determines its internal temperament and aesthetic feeling, while "body decoration" is the decoration of the font, which can affect the style and appearance of the font. Center and center of gravity are absolute "centers" in physics, but people feel low at first sight because people's eyes have visual errors. If you design fonts according to the physical center, it will make people feel that the middle part is downward, which is why most fonts focus on the visual center.
When designing fonts, should the stroke thickness be the same? The answer is no, because the complexity of strokes varies from word to word, and strokes with the same thickness will give people a feeling of inconsistent thickness when they are horizontal, vertical, oblique and curved, because people will have an optical illusion when they look at things, so they should adjust the thickness of strokes according to the complexity and visual feeling of fonts when creating words to achieve visual unity. The following figure is a rectangle with exactly the same physical width, and its visual thickness relationship is: horizontal >; Oblique > vertical > curved.
A square with exactly the same side length looks a little high, or it is the influence of optical illusion. Therefore, when making square characters, the outer frame should be flattened to eliminate the influence of optical illusion.
The size of the middle palace will affect the temperament of the font and the recognition of the font in extreme environment. Usually, the font of Xiaozhonggong looks more delicate, but it is not experienced well in small fonts or long-distance recognition (such as screen fonts and high-speed street sign fonts). The font with a large size in Zhonggong looks more stable and clumsy in temperament, and it is better in recognition than the font with a small size in Zhonggong because of the large white space inside.
Unified formal language is the basis of good design, which has been repeatedly proved in modern art blocks. Whether painting, architecture, posters, industrial design, etc. We can see the classic case of unified formal language. The balance between positive and negative spaces is biased towards traditional fonts.
