戒指尺码对照表与转换器
戒指尺码都源于指环内径或内周,只要知道毫米数就能精确转换。美码每档内径相差约0.8mm(7号为17.3mm),英码用A到Z字母加半档(N为17.1mm),欧码和ISO直接用周长毫米(54即周长54mm),日本用1到27号,13号内径17.1mm。中国大陆常见的港码与日本号数基本一致。
测量方法:把纸条绕手指根部一圈,标出重叠处,量出长度(毫米)即为周长;或直接量一枚合适戒指的内径。手指在炎热天气和运动后会肿胀,请在室温下、下午测量。宽度超过6mm的戒指会更紧,建议大四分之一到半码。指关节粗的人,要选刚好能过关节的尺码。

常见问题
美码7号戒指对应英码、欧码和日本号数多少?▾
美码7号内径17.3mm、周长54.4mm,对应英码N到N.5、欧码/ISO 54、法码54、日本13到14号。美码6是16.5mm(英码L.5、欧码52),美码8是18.1mm(英码P.5、欧码57)。
没有戒指尺测怎么量尺码?▾
用纸条或线绕手指根部一圈,标出重叠处并量长度,该毫米数即周长,也就是欧码。54mm是美码7,57mm是美码8,60mm是美码9。测三次取平均。
半码相差多少?▾
美码半码约相差内径0.4mm、周长1.3mm,感觉明显:小半码往往过不了关节。多数珠宝店可改大或改小两码以内。
宽版戒指需要选不同尺码吗?▾
需要。宽度6mm以上的戒指覆盖手指面积更大、更紧,建议大四分之一到半码。宽度2mm以下的细戒指可按实测尺码下单。
