Size Guide

Everything you need to find the right fit for rings, necklaces, and bracelets.

How to measure at home

No sizing kit? Wrap a thin strip of paper around the base of the finger, mark where it overlaps, then measure the length flat with a ruler. Compare that measurement — or the internal diameter of a ring that already fits — against the chart below.

Tip: measure at the end of the day, when fingers are at their largest, and avoid measuring right after exercise or in cold weather.

Internal diameter	Circumference	UK size	US size
14.9mm	46.8mm	H	4
15.7mm	49.3mm	J	4.75
16.5mm	51.9mm	K	5.5
17.3mm	54.4mm	M	6.25
18.2mm	57.2mm	N	7
19.0mm	59.7mm	P	7.75
19.8mm	62.2mm	Q	8.5
20.6mm	64.8mm	S	9.25
21.4mm	67.3mm	T	10

Figures are approximate. If you're between two sizes, we generally recommend sizing up — especially for wider band styles.

Necklace length is measured from end to end of the chain, and determines where the piece sits on the body. As a general guide:

Length	Style	Sits at
35–40cm	Choker	Base of the neck
40–45cm	Princess	Collarbone
45–50cm	Classic	Just below collarbone
55–60cm	Matinee	Top of the bust
70cm+	Opera	Below the bust

Not sure what will suit you? A quick way to check is to measure a necklace you already own and love, and match it against the chart above.

Wrap a soft measuring tape (or a strip of paper) around your wrist, just below the wrist bone, where the bracelet will naturally sit. Add a little room for comfort based on how you like it to fit:

• Snug fit — add 1cm to your wrist measurement.
• Comfortable fit — add 1.5–2cm to your wrist measurement.
• Loose, dangling fit — add 2.5cm or more to your wrist measurement.

Wrist size	Suggested bracelet size
14–15cm	15.5–16.5cm (S)
15–16cm	16.5–17.5cm (M)
16–18cm	17.5–19cm (L)
