Finding the perfect fit is part of choosing a piece that feels truly yours. Use the guide below to help determine your ring size with confidence and ease.
Measure a Ring You Already Own
One of the easiest ways to estimate your ring size is by measuring the inside diameter of a ring that already fits comfortably on the intended finger.
Use a ruler to measure the inner width in millimeters and compare it to the chart below.
Ring Size Chart
| US Size | Inside Diameter (mm) | Inside Circumference (mm) |
|---|---|---|
| 4 | 14.8 | 46.8 |
| 5 | 15.7 | 49.3 |
| 6 | 16.5 | 51.9 |
| 7 | 17.3 | 54.4 |
| 8 | 18.1 | 57.0 |
| 9 | 18.9 | 59.5 |
| 10 | 19.8 | 62.1 |
Measure with String or Paper
Wrap a thin strip of paper or string comfortably around the base of your finger. Mark where the ends meet, then measure the length in millimeters.
Compare this measurement with the circumference column in the chart above to estimate your ring size.
Professional Sizing & Helpful Tips
If you want added reassurance, a professional jeweler can size your finger using a ring mandrel or sizing set. This can be especially helpful for wider bands or special designs.
- Measure at the end of the day for the most accurate fit.
- If you are between sizes, we generally recommend sizing up.
- Wider bands may feel more snug and sometimes require a slightly larger size.
Choosing a Size for a Surprise
If you are shopping for a gift or proposal and do not know the exact size, a ring your recipient already wears on the correct finger can be a helpful guide.
