Chinese Characters - Variants

Variants

Just as Roman letters have a characteristic shape (lower-case letters mostly occupying the x-height, with ascenders or descenders on some letters), Chinese characters occupy a more or less square area in which the components of every character are written to fit in order to maintain a uniform size and shape, especially with small printed characters in Ming and sans-serif styles. Because of this, beginners often practise writing on squared graph paper, and the Chinese sometimes use the term "Square-Block Characters" (方块字 / 方塊字, fāngkuàizì), sometimes translated as tetragraph, in reference to Chinese characters.

Despite standardization, some nonstandard forms are commonly used, especially in handwriting. In older sources, even authoritative ones, variant characters are commonplace. For example, in the preface to the Imperial Dictionary, there are 30 variant characters which are not found in the dictionary itself. A few of these are reproduced at right.
