Starting question
How can I pick the correct ring size online for a Sardinian filigree ring, without ending up with a ring that’s too tight or too loose?
Quick answer
Measure a ring that already fits the same finger: check the inner diameter in millimeters and match it to a size chart. If you don’t have a reference ring, measure your finger circumference with paper/string twice at different times of day. For gifts, measure one of their rings or rely on support/exchange options.

Most accurate method: measure a ring you already wear
Choose a ring that fits perfectly on the same finger.
Measure the inner diameter (inside edge to inside edge) in mm.
Match that number to a ring size chart.
Tip: measure twice, ideally with a caliper.
Alternative method: measure finger circumference
Wrap a thin paper strip or non-stretch string around the base of your finger.
Mark where it meets and measure the length in mm.
Repeat at least twice.
Common mistake: measuring only in the morning or pulling too tight.
Best time to measureFingers change size during the day. Heat, exercise, and hydration matter.Rule of thumb: measure once in the afternoon and once in the evening. If values differ, choose the more comfortable size.
Dominant vs non-dominant hand
Your dominant hand is often slightly larger. Don’t assume the same size across hands.
Buying as a gift: 3 reliable strategies
A) “Borrow a ring”: measure a ring they wear often (same finger if possible).
B) Ask someone close to them.
C) If in doubt, go slightly larger and rely on exchange/support.
Key detail: band width matters
Wider bands can feel tighter. If you’re between sizes, consider sizing up slightly for comfort.
Conclusion
With the inner-diameter method, choosing a ring size online becomes simple and accurate. A few extra minutes measuring saves you headaches later.
