We list ring sizes in US sizes. Many of our rings also show the Australian/UK letter size and the inside circumference in mm.
How to measure a ring you already own: measure the inside diameter (edge to edge, across the middle) in millimetres, then find the closest match below.
How to measure your finger: wrap a thin strip of paper around the base of your finger, mark where it overlaps, then measure the length in mm. That’s your circumference.

Tips: measure at the end of the day when fingers are warmest, and if you’re between sizes choose the larger size, especially for wide bands (6 mm or more).
| Length | Where it usually sits |
|---|---|
| 16″ (40 cm) | Base of the neck, like a choker on most women |
| 18″ (45 cm) | On the collarbone, the most popular length for pendants |
| 20″ (50 cm) | Just below the collarbone |
| 22″ (55 cm) | A few centimetres below the collarbone; a common men’s length |
| 24″ (60 cm) | Top of the chest; great for layering or larger pendants |
Many of our necklaces have two or three lock points (for example 16″ and 18″), so you can change the length. Layering? Allow about 2″ (5 cm) between each chain.
Measure around your wrist bone with a soft tape measure (or a strip of paper), then add about 1–2 cm for a comfortable fit.
| Wrist | Bracelet length |
|---|---|
| 14–15 cm | 16 cm / 6.5″ |
| 15–16 cm | 17 cm / 6.75″ |
| 16–17 cm | 18 cm / 7″ |
| 17–18 cm | 19 cm / 7.5″ |
| 18–19 cm | 20 cm / 8″ |
Bangles don’t open, so measure around the widest part of your hand with your fingers pressed together, or ask us to check your size in store.
