bracelet size guide
Use the method below to visualise how each bracelet length sits on the wrist. Whether you prefer a close daily fit or a looser, layered feel, this will help you choose.
- Wrap a soft measuring tape, ribbon, or string just below your wrist bone, where your bracelet would naturally rest
- Mark where the end meets the loop
- Lay it flat and measure it with a ruler in cm or mm
-
Choose your fit:
- Snug — add 1 to 1.5 cm
- Standard — add 1.5 to 2 cm
- Loose — add 2.5 cm or more
If you are unsure, we are here to help. Send us your wrist length and how you would like it to sit.
