Getting the size right matters more than getting it right first time. If it does not fit, we resize it — see Returns & Exchanges.
Measuring at home
The most reliable method is to measure a ring the wearer already owns and wears on the right finger.
- Take a ring that fits the intended finger.
- Measure the inside diameter across the widest point, in millimetres.
- Email us that measurement and we will convert it to a size.
Measuring the finger itself with string or paper is less accurate, because string stretches and paper does not slide over the knuckle the way metal does. If it is your only option, wrap it snugly around the base of the finger, mark where it overlaps, and measure that length in millimetres — that is the circumference.
Things that change the answer
- Time of day. Fingers are smallest in the morning and largest in the evening and in heat. Measure late in the day.
- Temperature. Cold hands can read a full size smaller.
- Knuckles. If the knuckle is noticeably wider than the base of the finger, size to the knuckle — a ring that will not go on is worse than one slightly loose.
- Band width. Wide bands fit more tightly than narrow ones. For a band over about 6mm, consider going up a quarter to a half size.
Buying as a surprise
If you are proposing and cannot measure, order the size you believe is closest. We would rather resize it afterwards than have you reveal the surprise. Borrowing a ring she already wears, and sending us its inside diameter, is the method that goes wrong least often.
