由“疏”“密”两个意义相反的词构成，有稀疏与稠密、简略与详细、粗疏与精密、宽松与严密、疏远与亲密等含义。在书法绘画等艺术批评中，疏密主要指结构或布局方面的安排以及笔墨运用的浓淡粗细等。在文学批评中，“疏”与“密”经常联用，“疏”义为疏荡、疏阔、粗略等，多指诗文创作中的随意、粗疏、不严密；“密”义为精密、严密、紧凑等，多指诗文创作中在构思、逻辑、用语等方面严谨周密，有时亦指密集堆砌的毛病。中国古人认为，“疏”与“密”对立统一，好的作品在结构、布局上应当疏密相间。

This concept consists of several pairs of opposites: sparsity and density, brevity and thoroughness, roughness and precision, flexibility and rigor, and estrangement and intimacy. In the artistic criticism of painting and calligraphy, the term is used to mainly describe the structural arrangement, general layout, as well as dark or light, thick or thin execution of strokes in these two art forms. In literary criticism, "sparsity" and "density" often occur together. "Sparsity" means carefree, rough or sketchy. It refers especially to thoughtlessness, carefreeness or looseness in the creation of prose and poetry. "Density" means meticulous, tight or compact. It often refers to rigor and thoroughness in theme development, logic, and wording in the creation of prose and poetry, and occasionally to the demerit of piling too many words up for no good reason. Ancient Chinese believed that sparsity and density represent a unity of opposites. A good work of art should balance density with sparsity in both structure and layout.

Wang Xizhi wrote swiftly and skillfully, dipping his brush in the concave inkstone from time to time. His calligraphic writing, whether sparingly or densely spaced, looks truly beautiful. Both his regular script and cursive script were written with immense care. In repose, his flow of words can be likened to watching a city gate from far away. In motion, it can be likened to watching a meteorite in the sky. (Xiao Gang: In Answer to Prince Xiangdong for Kindly Presenting Me with a Calligraphic Work by Wang Xizhi)
