Finding your size
A ring is the one thing you own that has to fit exactly one finger, forever. Finding that number takes five minutes, a strip of paper and a ruler.
You will need a strip of paper about 10 cm long and 5 mm wide, or a piece of non-stretchy thread. Avoid elastic or ribbon, which give as you pull them.
- Wrap it around the base of the finger that will wear the ring, on the correct hand. It should sit snug against the skin without pressing into it.
- Mark where the strip overlaps with a sharp pencil, at the exact point where the edge of the overlapping end crosses.
- Check it clears your knuckle. Hold the loop closed at the mark and slide it off over the knuckle. It should pass with gentle resistance. If the knuckle stops it, loosen slightly and mark again.
- Lay the strip flat against a ruler and measure from the end to your mark, in millimeters.
- Subtract 40. That is your ring size: 54 mm becomes 14, 57 mm becomes 17. Round to the nearest whole number.
- Repeat two or three times, ideally on different days, and take the largest reading you get consistently.
Or measure a ring she already owns. Useful when the ring is a surprise. Borrow one she wears on the same finger of the same hand.
- Measure the inner diameter across the widest point, from inside edge to inside edge, with a ruler or calipers.
- Multiply by 3.14 to get the inner circumference.
- Subtract 40 for the size. A ring measuring 17.2 mm across is about 54 mm around, so a size 14.

Small things quietly ruin an otherwise careful measurement.
- Time of day. Fingers are at their smallest in the morning and in the cold. Measure in the evening, at normal room temperature.
- Heat and salt. Skip the measurement straight after exercise, a hot bath or a salty meal.
- Which hand. The dominant hand usually runs slightly larger. Measure the hand that will wear the ring.
- Band width. A wide band sits against more of your finger and feels tighter. For anything over 6 mm wide, go up one size.
- Falling between two sizes. Choose the larger one. A ring that will not go on is a problem; a ring that is a touch loose is a fitting.
If the size turns out wrong. Most of our settings can be resized by a size or two afterwards. Rings set with stones all the way around the band have far less room to move, so if the size is a guess, a smooth band is the safer choice. Write to us before you order and we will tell you what is possible for the ring you have in mind.
