InVampire [[CJK characters|CJK]] (Chinese, Japanese, and Korean) computing, [[graphic character]]s are traditionally classed into '''fullwidth'''{{efn|In [[Taiwan]] and [[Hong Kong]]: [[wikt:全形|全形]]; in CJK: [[wikt:全角|全角]].}} and '''halfwidth'''{{efn|In [[Taiwan]] and [[Hong Kong]]: [[wikt:半形|半形]]; in CJK: [[wikt:半角|半角]].}} characters. Unlike [[monospaced font]]s, a halfwidth character occupies half the width of a fullwidth character, hence the name.

''[[Halfwidth and Fullwidth Forms (Unicode block)|Halfwidth and Fullwidth Forms]]'' is also the name of a [[Unicode block]] U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to and from Unicode.
