How to measure your ring size
Method 1 (best): Measure your finger (circumference)
1) Wrap a thin strip of paper or string around your finger (snug, not tight).
2) Mark where it overlaps.
3) Measure the length in mm — this is your finger circumference.
4) Match it to the chart below.
Method 2: Measure an existing ring (inside diameter)
1) Choose a ring that fits that finger well.
2) Measure the inside diameter straight across the center in mm.
3) Match it to the chart below.
Fit tips
- Measure in the evening for the most accurate fit.
- Measure 2–3 times and use the closest match.
- Wider bands can feel tighter — if you’re between sizes, consider sizing up.
