The xin zixing (Chinese: 新字形; pinyin: xīn zìxíng; Jyutping: san1 zi6jing4; lit. 'New character forms') is a standardized form of Chinese character set. It is based on the 1964 "List of character forms of Common Chinese characters for Publishing" (印刷通用汉字字形表; Yìnshuà Tōngyòng Hànzì Zìxíngbiǎo) as compared to jiu zixing. The standard is based on regular script and popular characters, and changes are made to the printed version of Song (Ming) typefaces. This standard covers the simplified and traditional characters, which separates it from other standards. SimSun font (pre-installed in Windows) uses this standard, which shows variation with other regional standards such as MingLiU and Taiwan's KaiU, and with the regular script version of SimKai, which is the written character standard for China.

Taiwan's Standard Form of National Characters made changes to the printed version of Mingsong typefaces, varying greatly from the Table of Common Chinese character in printing press and featuring drastic changes to the Ming typefaces, e.g. changing ⻍ and 辶 to ⻎. The usage of calling the Standard Form of National Characters the xin zixing is more common in areas using traditional characters.
