Narrow Value in East Asian Width Unicode Property
Narrow is a classification for characters that occupy a single cell in traditional East Asian typographic grids, meaning they are rendered at the same width as an ASCII character, such as Latin letters, digits, and most punctuation. These characters are considered visually "half-width" compared to the full-width forms like CJK ideographs, and they do not require extra spacing when mixed with standard text. In practice, narrow characters are used in both vertical and horizontal writing systems without affecting line breaking or alignment, and they are distinguished from wide or ambiguous characters that may need contextual width decisions. This value helps software and fonts determine proper kerning, wrapping, and table layout, especially in mixed-language content where Japanese, Chinese, or Korean text appears alongside Western scripts, ensuring that narrow glyphs remain compact and consistent.
