A jewellery sizing guide helps customers accurately measure and select the right size for rings, bracelets, necklaces, and earrings.
Ring Sizing Guide
- Use a strip of paper or string and wrap it around the base of your finger. Mark where it overlaps, then measure the length in millimeters.
- Compare this measurement to a ring size chart. For example, 50 mm circumference generally equals Indian Size 10 or US Size 5.
- Alternatively, measure the inner diameter of a ring that fits you with a ruler, then match it to a sizing chart.
- For best results, measure your finger at the end of the day when fingers are warm, as finger size fluctuates based on temperature and time.

Tips for Accurate Sizing
- Always measure three to four times for accuracy.
- Consider wider bands that require a slightly larger size.
- If in doubt, consult a professional jeweller or use a printable sizing chart offered by many jewellers.
Sizing guides and conversion charts are typically provided on jewellery websites to make selection easy and error-free.
