Ring Sizing
The most accurate way to find your size is to visit a local jeweller and ask to have your finger measured — they’ll usually do it for free.
If that’s not possible, you can measure your finger at home:
- Cut a thin strip of paper or string.
- Wrap it snugly around your finger and mark where it overlaps.
- Measure the length in millimetres — that’s your finger’s circumference.
- Divide that by 3.14 to get the diameter of your finger.
- Look up your ring size using the form above.
