Ring size guide
If you are in doubt about how to choose the right ring size, you can use our chart as a guide and choose between two measurement methods listed that you can do at home and that will help you determine your ring size correctly
It's a good idea to measure your fingers at the end of the day when they are at their largest circumference. Don't do it when your fingers are cold because they tend to expand or contract depending on the weather and the size will not turn out to be accurate. The best time to size is in the evening when you are at room temperature.
If you are thinking of buying a ring as a gift but don't know the exact size, you can take one of the rings the person is wearing and determine in an easy way what its diameter is. Alternatively, if you already know which size you need, use the helpful conversion chart to make sure the ring size you order matches the size you want.
The sizes of our rings meet US and Canadian standards. No matter what the model, we use whole ring sizes (without half numbers): 4 to 12
METHOD 1: Measure the inner diameter of your ring
- Pick up a ring you have worn on the finger you want to order a new one for.
- Take a ruler, graduated with millimeters.
- Place the ring horizontally on a flat surface and measure its inner diameter. When measuring, do not include the metal part of the ring. Make sure to measure the ring at its widest part (see figure).
- Read off how many millimetres the diameter is
Example: : 15.9 mm is size 5 by US numbering standards.
| Internal diameter | American Standard | Circumference |
|---|---|---|
| 14.8 mm to 15.2 mm | 4 | 46, 47, 48 mm |
| от 15.6 mm до 16.0 mm | 5 | 49, 50 mm |
| от 16.5 mm до 16.9 mm | 6 | 51, 52, 53 mm |
| от 17.3 mm до 17.7 mm | 7 | 54, 55, 56 mm |
| от 18.2 mm до 18.6 mm | 8 | 57, 58 mm |
| от 18.9 mm до 19.4 mm | 9 | 59, 60, 61 mm |
| от 19.8 mm до 20.2 mm | 10 | 62, 63 mm |
| от 20.6 mm до 21.0 mm | 11 | 64, 65, 66 mm |
| от 21.3 mm до 21.8 mm | 12 | 67, 68 mm |
METHOD 2: Finger circumference in millimetres (mm)
- If you don't have a ring available in the size you want to order, get a paper band or thread. You can cut a piece of paper 15 cm long and 0.5 cm wide
- Wrap the paper tape (or thread) around your finger and mark with a pencil or pen the overlapping point forming the completed circle. Make sure the paper is applied tightly but not too tight (see figure below).
- Take a ruler graduated in millimeters and measure the tape to the marked places. This will enable you to calculate the circumference of your finger.
METHOD 3: Measurement with a professional
For your ring size to be the most accurate, it is advisable to have it determined by a jeweler in a studio.
