全角和半角,是计算机中,中、日、韩文的CJKV字符的显示格式。
传统上,英语或拉丁字母语言使用的计算机系统,每一个字母或符号,都是使用一字节的空间(一字节由8比特组成,共256个编码空间)来储存;而汉语、日语及韩语文字,由于数量大大超过256个,故惯常使用两字节来储存一个字符。在使用等宽字体(如DOS、部分文字编辑器等)的环境下,中日韩文字此时占据两倍于西文字符的显示宽度。所以,中、日、韩等文字称为全角字符,相比起来,拉丁字母或数字就称为半角字符。有时为了使字体看起来齐整,英文字母、数字及其他符号也由原来只占一个字空间,改为占用两个字的空间显示、使用两个字节储存的格式。
JIS X 0201编码表把日语的片假名放进一字节的空间,故又称为“半角片假名”。
