How to Measure Your Ring Size
01
Wrap
Wrap a thin strip of paper or string snugly around the base of your finger.
02
Mark
Mark where the ends overlap, then lay the strip flat and measure in millimetres.
03
Match
Match the millimetre measurement to the circumference column in the chart.
Necklace Length Guide
Standard chain lengths and where they typically fall.
| Style | Inches | CM | Fit Guide |
|---|---|---|---|
| Collar | 12–13" | 30–33 cm | Fits tightly around the neck. |
| Choker | 14–16" | 35–40 cm | Rests at the base of the neck. |
| Princess | 17–19" | 43–48 cm | Falls just below the collarbone. |
| Matinee | 20–24" | 50–61 cm | Sits between the collarbone and bust. |
| Opera | 28–36" | 71–91 cm | Falls below the bust or can be layered. |
| Rope / Lariat | 36"+ | 91+ cm | Can be worn long, doubled, or styled in layers. |
Bracelet Sizes
Wrist circumference + comfort allowance.
| Size | Inches | Centimetres |
|---|---|---|
| X-Small | 6.0–6.5" | 15.2–16.5 cm |
| Small | 6.5–7.0" | 16.5–17.8 cm |
| Medium | 7.0–7.5" | 17.8–19.0 cm |
| Large | 7.5–8.0" | 19.0–20.3 cm |
| X-Large | 8.0–8.5" | 20.3–21.6 cm |
For a snug fit, add less allowance. For a relaxed fit, choose the next size up.

For a comfortable fit, measure around your ankle and choose the size that allows your preferred movement and drape.
Sizing, Answered
Wrap a thin strip of paper or string snugly around the base of your finger, mark where it overlaps, then measure the length in millimetres. Match that number to the circumference column in our chart. For best accuracy, measure at the end of the day when fingers are warm.
Always measure the specific finger you plan to wear the ring on. Even fingers on the same hand can differ by half a size or more.
We recommend sizing up. Rings should slide on with light resistance and require a gentle pull over the knuckle. This is especially important for wider bands, which fit more snugly than thin ones.
Wrap a flexible measuring tape around your wrist just below the wrist bone. Add roughly 1.5 cm (½") for a comfort fit, or 2.5 cm (1") for a relaxed fit.
Hold a string against your neck at the length you'd like the necklace to fall, then measure it. Compare your number to the necklace length guide above. Layering looks best with 5 cm (2") between each chain.
Yes. Fingers shrink in cold weather and swell when warm or after exercise. Measuring at room temperature in the evening gives the most reliable size.
