Ring Size Guide
How to Measure Your Finger
1. Use a piece of thin piece of paper, floss, or non-stretchy string (ie. Embroidery thread stretches).
2. Wrap it snugly around the base of your finger.
3. Mark the point where it overlaps, forming a complete circle.
4. Using the metric side of a ruler, match the measurement to the INNER CIRCUMFERENCE column on the chart below.
You can also measure the INSIDE diameter of a well-fitting ring you already own and find the best match on the INNER DIAMETER column of the chart below.
FYI - To non-metric users: 10 mm make up 1 cm, the unit that is most often marked on our US rulers. We often use mm to measure jewelry because it is easier to get exact measurements.
| Ring Size | Inner Circumference | Inner Diameter |
|---|---|---|
| 6 | 51.9 mm | 16.5 |
| 7 | 54.5 | 17.3 |
| 8 | 57.0 mm | 18.2 |
| 9 | 59.5 mm | 19.0 |
| 10 | 62.1 mm | 19.8 |
| 11 | 64.6 mm | 20.6 |
