SIZE GUIDE

Rings, bracelets, and chain lengths — the measurements we quote and produce to. Sized to the Japanese standard we've built our craft on, with reference for other regions.

Rings

Wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length in millimetres. Enter it below and we will read the Japanese size off it — that is the size we quote and produce to.

Sizes outside this range, and resizing of an existing design, are quoted case by case — ask us before you order.

Method 01Measure a ring you already wearMeasure the inner diameter of the band in millimetres, then read across the table.

Method 02Measure the finger directlyWrap a strip of paper or a piece of string around the finger, mark it, and measure the length in millimetres. Divide by 3.14 for the approximate inner diameter.

Bracelets & bangles

Wrap a tape snugly around the wrist just above the wrist bone and read it in centimetres. Add 1 cm for a close fit, 2 cm for a looser one — the figure you give us is the finished inside length of the piece.

Wrist measures	Order length	Fit
Up to 15 cm	16 cm	Close fit on a small wrist
15 – 17 cm	18 cm	The standard length — most orders
17 – 20 cm	22 cm	Larger wrists, or a deliberately loose fit
Anything else	Made to order	Specify wrist measurement plus 1–2 cm ease

Custom lengths are made to order and add roughly two weeks to the schedule. Chain-link bracelets are adjusted a full link at a time, so the finished length may fall within ±0.5 cm of the figure ordered.

Chains & pendants

Hold a piece of string around the neck, let it hang where the pendant should sit, then measure it in centimetres. Lengths below are the finished chain including clasp.

Length	Where it sits
40 cm	Sits at the base of the neck. Close, collar-length.
45 cm	Just below the collarbone — the standard length for most pieces.
50 cm	Over the top of the chest. Clears a collar or a second chain.
55 – 60 cm	Pendant sits at the sternum. Common for heavier men’s pendants.
Pendant only	Supplied without chain, for customers who chain in-house.

Between two lengths? Take the longer one for pieces worn over clothing, the shorter for against the skin.
