Size guide

Ring size

Wrap a strip of paper round the base of the finger, mark where it meets and measure that length in millimetres. That is your circumference. Measure at the end of the day, when fingers are at their largest, and check the knuckle too — the ring has to pass over it.

UK size	Circumference	Diameter
J	48.7 mm	15.5 mm
K	50.0 mm	15.9 mm
L	51.2 mm	16.3 mm
M	52.5 mm	16.7 mm
N	53.8 mm	17.1 mm
O	55.1 mm	17.5 mm
P	56.3 mm	17.9 mm
Q	57.6 mm	18.3 mm
R	58.9 mm	18.8 mm
S	60.2 mm	19.2 mm

Between two sizes? Take the larger one. A ring that is slightly loose can be worn; one that does not pass the knuckle cannot.

Chain length

Measured end to end, including the clasp.

40 cm — sits at the base of the neck
45 cm — collarbone, the most common length
50 cm — just below the collarbone, works over a shirt
60 cm — mid-chest, sits over a jumper
70 cm and up — long, suits a pendant with some weight

Layering two chains? Leave at least 5 cm between them so they do not tangle.

Bracelet size

Measure round the wrist with a tape or a strip of paper, then add 1–2 cm for a comfortable fit. Add 2–3 cm if you prefer it loose. Bangles are rigid, so what matters there is whether the widest part of your hand passes through — measure across the knuckles with the thumb tucked in.

Earrings

Drop length is measured from the top of the fitting to the lowest point. Post, hook or clip is listed on each product, along with the weight — anything over about 8 grams per earring is noticeable after a few hours.
