戒圍測量
戒指的指圈大小標準稱為戒圍，以號碼表示。我們採用「國際圍」，是一般台灣銀樓或專櫃常用的戒圍標準。若您已知的戒圍是使用美國圍、香港圍、或其他戒圍標準，也可以提供給我們，我們會以該標準製作戒指或是協助您轉換尺寸。若您不知道您的戒圍號碼，最好的方式是到鄰近的銀樓或專櫃，使用專業的戒圍圈測量，或是可參考下列方式在家自行測量指圍。
如何找到最適合的戒指尺寸？
由於手指在夏天及冬天時，會依溫度高低而有熱漲冷縮的現象，相差大約 0.5 ~ 1 號圍之間，因此在選購戒指時，建議夏天戴上後稍緊、冬天戴上後可稍稍左右轉動但不脫落為宜。除此之外，手指在清晨時或溫度低時會較小，建議可在傍晚時分或手指溫暖時測量戒圍。您的戒指應能舒適地緊貼手指，緊密程度足以讓戒指不易滑落，而又能穿過手指關節。
如何使用平常佩戴的戒指測量？
將平常配戴且未變形的戒指平放在尺上 (請先確定該戒指的戒圍大小是適合的)，測量「戒指內圍直徑」並對照頁尾的表格，就能找到您的戒圍號碼。
如何使用沒有彈性的線或紙條測量？
找一條「沒有彈性」的線或紙條，繞一圈在您欲佩戴戒指的手指底部，在線或是紙條的重疊處做個記號，再用尺測量這條線或紙條的長度，將所得「戒指內圍周長」對照頁尾的表格，就能找到您的戒圍號碼。切勿將這條線或紙帶收太緊，確保測量的線或紙張也可以穿過指節，因為手指的關節往往略大於戴戒指的地方。建議多測量幾次，以消除誤讀的可能性。
Ring Size Guide
At Joyce Wu, the rings are in Taiwan International sizes, but you can also provide us with your ring size in other standards such as US, UK or HK Size if you have one already – we will be gladly to make a ring in that size.
We highly recommend you visit a local jeweler for a professional ring size measurement. A jeweler will probably use a set of finger gauges, often called a ring sizer, which contains a series of metal bands in ½ size increments. If you want to measure it at home, you can use a ring you already have, or a piece of string or a strip of paper to measure your finger.
How to get the perfect fit?
Fingers are smaller in the early morning and when cold, so for best results, measure your finger size at the end of the day and when your fingers are warm. Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle. If the ring falls between two sizes, order the larger size.
How do I find my ring size with a ring that I own?
Find a ring you own that fits the finger you are trying to size. Use the ruler to measure the diameter of the inside of the ring, and then look up the measurement on the chart below to find the corresponding ring size (Inside Diagram).
How do I use non-stretchy string or paper as a ring sizer?
- Take a piece of non-stretchy string, ribbon, thread, or a thin strip of paper and wrap it snugly around the base of your finger. With a pen, carefully mark the point on the string or paper where it overlaps, forming a complete circle.
- Lay it flat and use a ruler to measure the length in millimeters. This is the circumference of your finger.
- Use the chart below to find the corresponding ring size (Inside Circumference).
- If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. It is always a good idea to measure your finger size 3 to 4 times to eliminate an erroneous reading.
