MEASURE TWICE, WEAR FOREVERMeasure your ring size
- 01
Use a ring that fits
Measure the inside diameter of a ring you already wear on that finger, edge to edge, in millimetres.
- 02
Or wrap your finger
Wrap a strip of paper around the base of your finger, mark where it overlaps and measure the length (circumference).
- 03
Match the chart
Find the closest measurement below. Between sizes? Choose the larger one, especially for wide bands.
- 04
Measure at the right time
Fingers are larger at the end of the day and in warm weather. Measure 2–3 times for accuracy.

Bracelet sizes
Measure your wrist just below the wrist bone with a soft tape, then add about 1.5–2 cm (½–¾ inch) for a comfortable fit. Tennis bracelets are best close to the wrist; chains can sit looser.
| Wrist size | Bracelet length | Size |
|---|---|---|
| 14 – 15 cm (5.5 – 6 in) | 16.5 cm (6.5 in) | Small |
| 15 – 16.5 cm (6 – 6.5 in) | 17.8 cm (7 in) | Medium |
| 16.5 – 18 cm (6.5 – 7 in) | 19 cm (7.5 in) | Large |
| 18 – 19 cm (7 – 7.5 in) | 20.3 cm (8 in) | Extra large |
| 19 cm + (7.5 in +) | 21.6 cm (8.5 in) + | Custom length |
Where each length sits
Where a chain falls depends on your neck size and build. Measure an existing necklace end to end (including the clasp) to compare.
| Length | Name | Where it sits | Good for |
|---|---|---|---|
| 14 – 16 in (35 – 40 cm) | Choker / collar | Base of the neck | Tennis necklaces, layering top strand |
| 18 in (45 cm) | Princess | On the collarbone | Pendants — the most popular length |
| 20 in (50 cm) | Matinee (short) | Just below the collarbone | Larger pendants, crew necks |
| 22 in (55 cm) | Matinee | Upper chest | Chains worn alone, men's pendants |
| 24 in (60 cm) | Long | Mid chest | Statement pendants, over shirts |
| 30 in + (75 cm +) | Opera | Below the bust | Layering and long chains |
Pendants add their own drop — allow extra length for a large pendant so it sits where you want.
