Product size note: This chart is a reference. Some product labels, including SG11, SG13.5, SG17 and SG18.5, have no exact row below, and size-number conversions differ between jewellers. Email hello@guildbullion.com with the product link and size for its exact inner measurement before ordering.

Find your Guild Bullion jewellery fit. Measure in centimetres (cm) or millimetres (mm), and check each product's exact dimensions before ordering.

Rings: Singapore / Hong Kong sizes

Singapore and Hong Kong ring numbers are commonly used together. Measure the inside circumference of a ring that fits, or wrap a narrow paper strip around your finger and measure it in mm. Measure near the end of the day. Wide bands can feel tighter. If between sizes, ask us before ordering.

SG / HK	Inside circumference	Inside diameter
6	44.5 mm	14.2 mm
8	45.2 mm	14.4 mm
9.5	47.6 mm	15.2 mm
10.5	49.2 mm	15.7 mm
12	50.6 mm	16.1 mm
13	51.9 mm	16.5 mm
14.5	53.2 mm	16.9 mm
15.5	54.0 mm	17.2 mm
16.5	55.6 mm	17.7 mm
17.5	57.2 mm	18.2 mm
18–19	58.7 mm	18.7 mm
20	60.3 mm	19.2 mm
21	61.9 mm	19.7 mm
23	63.5 mm	20.2 mm
24	65.1 mm	20.7 mm

Measurements are approximate and size labels can vary by maker. Use the dimensions stated on the individual product if they differ.

Bracelets

Measure your wrist just below the wrist bone. Add about 1–2 cm for comfort. Adjustable and chunky designs may fit differently.

Wrist	Suggested bracelet length
14 cm	15–16 cm
15 cm	16–17 cm
16 cm	17–18 cm
17 cm	18–19 cm
18 cm	19–20 cm
19 cm	20–21 cm

Bangles

For a slip-on bangle, measure around the widest part of your hand with your thumb brought toward your little finger. For a hinged bangle, compare its inner circumference with your wrist. A bangle you already own can be measured straight across its inside diameter.

Inside diameter	Approx. inner circumference
5.5 cm	17.3 cm
5.6 cm	17.6 cm
5.7 cm	17.9 cm
5.8 cm	18.2 cm
5.9 cm	18.5 cm
6.0 cm	18.8 cm

Oval and thick bangles can fit differently; these are geometry conversions, not fixed size numbers.

Necklaces and chains

Length	Typical position
35–38 cm	High on neck
40 cm	Base of neck
45 cm	Collarbone
50 cm	Below collarbone
55–60 cm	Upper chest
70 cm+	Long layering

Position varies with neck size, chain thickness and pendant weight. Try a string at the listed length to preview the drop.

Anklets, earrings and pendants

Anklets: Measure above the ankle bone and add about 1–2 cm for movement. Earrings: Compare the product's drop, width and weight; there is no universal size number. Pendants and charms: Check height, width and bail opening against your chain.
