How to measure
Use string or paper
Wrap a thin strip of paper or string around the base of your finger. Mark where it joins. Measure the length in mm — that's your inner circumference. Divide by π (3.14) to get your inner diameter, then match it to the chart.
Section 02
Bracelet & Bangle Sizing
Bangle size is measured as inner diameter. For flexible bracelets, measure your wrist and add 1cm of ease.

How to measure
Wrap your wrist
Wrap a tape measure around your wrist where you'd wear the bracelet — not too tight. Add 1cm for comfortable ease. That's your bracelet length.
Section 03
Necklace Lengths
Consider the shape and size of the pendant, the neckline you wear most, and where you want the piece to sit.
