Size Guide
Getting the fit right, the first time
Measuring instructions, full conversion charts and the practical notes that change the answer — for rings, bracelets, necklaces and earrings.
Rings
Ring size is the inside circumference of the band, measured in millimetres and then expressed on a national scale.
How to measure: Cut a strip of paper about 6mm wide, or take a length of non-stretch string. Wrap it around the base of the finger, snug but not tight — it must slide over the knuckle. Mark where the strip overlaps, lay it flat and measure to the mark in millimetres. That measurement is the inside circumference. Find it in the first column and read across.
Worth knowing: Measure at the end of the day and at room temperature. Fingers are smallest in the morning and in the cold, and can differ by a full size. If the knuckle is much larger than the base of the finger, size for the knuckle and ask us about sizing beads — they stop the ring spinning. Wide bands fit tighter than narrow ones. For anything above 6mm, go up half a size. Measure the exact finger the ring is for. The dominant hand is usually a quarter to a half size larger. Between two sizes? Take the larger. A ring can be taken in far more easily than it can be let out.
Bracelets & bangles
Bracelets are measured by wrist circumference; a bangle is measured by its own inside diameter, because it has to pass over the hand.
How to measure: Wrap a tape measure around the wrist just below the wrist bone, where the bracelet will sit. For a comfort fit, add 2cm to that measurement. For a close fit — tennis bracelets and rivières — add 1cm. For a bangle, press the thumb into the palm and measure around the widest part of the hand, then divide by 3.14 to get the inside diameter you need.
Worth knowing: A charm or tennis bracelet should move about 1cm along the wrist. If it does not move at all, it will catch on cuffs. A bangle that clears the hand easily will spin. Size it as close to the hand measurement as it will pass. Most of our bracelets carry two adjustment links, so half a centimetre either way is nothing to worry about.
Necklaces & chains
Chain length is measured end to end, clasp included, and decides entirely where the piece falls.
How to measure: Take a length of string and hang it around the neck where you would like the piece to fall. Mark the point at the back of the neck where the two ends meet, then lay the loop flat and measure it. That total length is the chain length to order — clasp included.
Worth knowing: To layer well, leave 5cm between chains. Any closer and they tangle. A heavier pendant pulls a chain forward, so it will sit a little lower than the chart suggests. For a high neckline, 45cm and above keeps the pendant visible; for an open neckline, 40cm frames it best. Our chains carry a 5cm extender as standard, so one length covers two positions.
Earrings
Earrings are sized by the dimensions of the piece itself, and by the diameter of a hoop.
How to measure: For hoops, measure the outside diameter of a pair you already own and like — that is the number quoted on our listings. For drops, measure from the earring's own top edge to its lowest point; that is the full drop, and roughly how far it will hang below the lobe.
Worth knowing: Anything above 4 grams per earring will feel heavy after a few hours. Ask us for the weight; we publish it. For a stretched or sensitive lobe, choose a stud with a flat back or a huggie — both distribute weight across the piercing. Hoops with a hinged snap close more securely than a friction post and are far harder to lose.

Every piece we make can be resized once, free, within the first year. Full eternity bands and some tension settings are the exceptions, and we will always say so before you order.
