To measure your finger using the reference chart below:
- Wrap a string around your finger.
- Find the length of the string that wraps around your finger exactly one time.
Measure that length of string against the closest circumference below.
If you have an existing ring available, it is easy to align the ring with one of the circles above. Simply place the existing ring with the inside edge of the ring fitting against the matching circle.
