The difference between them is:
Font and calligraphy are two different concepts. Font refers to the standard form of Chinese characters composed of stippling and radicals according to certain structural rules, which is the basis of calligraphy. The style of calligraphy refers to the style of writing with a brush, which is symmetrical with the font. The font is strict and mechanical, and the rules are observed; Calligraphy is a line creation activity in which calligraphers express their spirit and intuition according to fonts. As far as the relationship between the two is concerned, there is a lively multi-head style first, and then there is a strict font that is established and observed by everyone. In the meantime, there are five changes in calligraphy style: seal, official script, grass, line and model; Fonts have always had standard fonts at that time.
