   Determining the right ring size, particularly with facets on the inside, can be challenging. That’s why you’re here to find some helpful guidance.

Ring dimensions

We use the International standard system ISO (8653:2016), which defines ring sizes in terms of the inner diameter Ø of the ring and is measured in millimetres:

Ring sizes

Our standard sizes are 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68 and 70, which you can find in the size guide. We also offer custom sizes on request →

Ring measurement

1. Measure with an existing ring — Place an existing ring on the circles until you find the one that matches the inner diameter of your ring.

2. Measure with the templates — Cut out the templates along both the outer and inner edges (not along the dashed line). Then carefully insert your finger through the hole and determine your size.

3. Measure with the ring sizer — Cut out the sizer, pull the tab through the slit, and wrap it around your finger. Pull it tight until the size fits comfortably, but make sure it can still slide over your knuckle.

Our bangle is available in four different sizes — S, M, L and XL. You can find all the templates to cut out in the document below.

Bangle measurement

XFPD128M4
XFPD128L4
XFPD128XL4

36 cm or 46 cm

Chain length
Measure with a string — Cut a string to your preferred length and place it around your neck to ensure a comfortable fit. Please note that our pendant sits horizontally, which may visually shorten the chain length. The full length of the chain incorporates the 1.5 cm swivel.
