SIZE GUIDE
MEASURE ONCE. WE DO THE CONVERSION.
Every chart below is the standard international conversion, not a table we invented. Each product page has the same numbers and a calculator that reads them.
Rings — measure the ring, not the finger
The most reliable method: take a ring that already fits that finger and measure its inner diameter in millimetres, across the widest part of the inside. Match it to the table.
No ring to measure? Wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length — that is the circumference.
Measure at the end of the day when fingers are at their largest, and never over a knuckle that is much wider than the base. If you fall between two sizes on a signet, take the larger one: a signet that spins is worse than one that is slightly snug.
CUBAN CHAIN
| Size | Length |
|---|---|
| 50 cm | 50 cm |
| 55 cm | 55 cm |
| 60 cm | 60 cm |
50 cm sits at the collarbone, 55 cm just below it, 60 cm mid-chest. Measured end to end including the clasp.
SIGNET RING
| Size | Inner diameter | Circumference |
|---|---|---|
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
US sizing. Inner diameter and circumference are the standard international equivalences, not our own measurements — measure a ring you already wear across its inside and match the diameter.
BANGLE
| Size | Circumference |
|---|---|
| S | 165 mm |
| M | 180 mm |
| L | 195 mm |
Inner circumference in millimetres. Measure just above the wrist bone with a tape and add 10–15 mm for a comfortable fit.
ROPE CHAIN
| Size | Length |
|---|---|
| 50 cm | 50 cm |
| 55 cm | 55 cm |
| 60 cm | 60 cm |
50 cm sits at the collarbone, 55 cm just below it, 60 cm mid-chest. Measured end to end including the clasp.
FIGARO CHAIN
| Size | Length |
|---|---|
| 50 cm | 50 cm |
| 55 cm | 55 cm |
| 60 cm | 60 cm |
50 cm sits at the collarbone, 55 cm just below it, 60 cm mid-chest. Measured end to end including the clasp.
Watches — there is no size, but there is a fit
A watch case does not come in sizes. What matters is how its diameter reads against your wrist. Measure your wrist circumference with a tape just above the wrist bone, then:
- 15–16 cm — 36 to 39 mm sits best. A 42 mm case will overhang.
- 16–18 cm — 38 to 42 mm. The widest comfortable range.
- 18–20 cm — 40 to 44 mm. A 40 mm case reads as a dress watch.
- Over 20 cm — 42 mm and up.
Thickness matters as much as diameter for whether it slips under a cuff. Every product page lists both, and the size finder will give you an opinion on your specific wrist.
Chains — it is a decision, not a measurement
Length is about where you want it to sit, not about anatomy. On an average adult neck: 50 cm rests at the collarbone, 55 cm just below it, and 60 cm sits mid-chest. Add roughly 2 cm for every 2.5 cm your neck measures above 40 cm.
A 12 mm curb carries visual weight. If you are between two lengths, take the shorter one.
