Ring Size Guide
Finding the right ring size helps ensure a comfortable and secure fit. Use the methods below to estimate your ring size before ordering.
Method 1: Measure an Existing Ring
Choose a ring that fits the intended finger well. Measure the inside diameter straight across the center of the ring in millimeters, then compare your measurement with the chart below.
| US Size | Inside Diameter | Finger Circumference |
|---|---|---|
| 4 | 14.9 mm | 46.8 mm |
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
Method 2: Measure Your Finger
Wrap a thin strip of paper or non-stretch string around the base of your finger. Mark where the ends meet, then measure the length in millimeters. This measurement is your approximate finger circumference.
Tips for the Best Fit
- Measure your finger at the end of the day when fingers are typically slightly larger.
- Avoid measuring when your hands are unusually cold or hot.
- Make sure the ring can pass comfortably over your knuckle.
- If you fall between two sizes, the larger size is often more comfortable.
- Wider ring bands can feel tighter than thin bands.
Measurements are approximate and may vary slightly depending on ring design and band width.
