Get the size right the first time.
Every ring is crafted to order, so the size you give us is the size it's made in. Two minutes of careful measuring now saves weeks later. If you're unsure, book a consultation and we'll walk through it together before anything goes into production.
Three ways to measure at home
Paper strip method
Cut a strip of paper about 4 inches long and a quarter inch wide. Wrap it snugly around the base of the finger, mark where it overlaps, then lay it flat and measure to the mark in millimetres. That number is your circumference — match it to the chart below.
Measure an existing ring
Place a ring that already fits that finger on a ruler and measure the inside diameter in millimetres, edge to edge. Multiply by 3.14 for circumference, or tell us the diameter and we'll convert it for you.
Measure at the right moment
Fingers swell in heat and after exercise, and shrink when cold. Measure at the end of a normal day at room temperature, and take three readings on separate days. If two of the three agree, that's your size.
US size to circumference
Circumference is given in millimetres. If your measurement falls between two rows, round up — a ring that's a hair loose is far easier to live with than one that won't clear the knuckle.

Details worth knowing before you order
- Wide bands run tight
- Anything 6mm or wider sits against more skin and feels snugger. Go up a quarter to a half size from your standard measurement for wide or comfort-fit bands.
- Eternity rings can't be resized
- A band set with diamonds all the way around has no plain metal to cut and rejoin. These are crafted to the exact size you confirm, so treat that measurement carefully — a professional sizing before you order is worth the trip.
- Large knuckles
- Size to slide over the knuckle, then let us know: we can add sizing beads or a small internal bar so the ring doesn't spin once it's on.
- Buying as a surprise
- Borrow a ring she already wears on that hand and trace the inside circle, or ask us on a consultation call. If it's off, resizing is available for a fee on eligible styles.
