Ring Sizes – How to Find Your Size
To ensure your boops ring fits perfectly, here's how to find your ring size. The most accurate way is to either measure a ring that already fits you well, or directly measure the circumference of your finger.
Method 1: Measure a ring
Measure the inside diameter of a well-fitting ring from inner edge to inner edge and compare the value with the table below.
Method 2: Measure your finger
Wrap a thin strip of paper or thread around your finger, mark where the ends meet, and measure the length in millimeters. This is your inside circumference.
Size chart
| Ring Size (EU) | Inside Circumference | Inside Diameter |
| 52 | 52.0 mm | 16.6 mm |
| 54 | 54.0 mm | 17.2 mm |
| 56 | 56.0 mm | 17.8 mm |
| 58 | 58.0 mm | 18.5 mm |
Tips for accurate measurement
- It's best to measure in the evening – fingers are slightly thicker then than in the morning.
- Measure when your hands are warm; fingers become narrower when cold.
- If you are between two sizes, choose the larger one.
- The ring should fit over your knuckle but not be too loose.
