The Ming dynasty calligrapher known for refined regular script often called “Wen style” was Wen Zhengming.
Wen Zhengming was a major Ming scholar-artist from Suzhou, active from 1470 to 1559. He became especially renowned for small regular script, or kaishu, whose carefully controlled strokes, balanced proportions, and precise structure helped define the elegant manner associated with his name. This refined approach is often referred to as Wen style.
Wen did not limit himself to one form of writing. He also produced semi-cursive, cursive, seal, and clerical scripts, and his work reflects sustained study of earlier masters. His regular script was particularly influenced by the Jin dynasty calligraphers Wang Xizhi and Wang Xianzhi, while other aspects of his calligraphy show engagement with Song masters such as Huang Tingjian.
A common mix-up is to treat “Wen style” as a formal script category. It is better understood as the personal manner of Wen Zhengming within regular script, especially his small, meticulous kaishu. Wen was also one of the celebrated Four Masters of Ming painting and a central figure of the Wu school.
