Ring Sizing Guide
Every Soul Sparkle ring is made to order, so we cast it in the size you choose. Take a minute to measure first — a good fit should slide over the knuckle with a little resistance and sit snugly at the base of the finger.
Three ways to find your size
1. Measure a ring you already own
Lay the ring on a ruler and measure the inside diameter in millimetres, then find it in the chart below. This is the most reliable method.
2. Measure your finger
Wrap a thin strip of paper or a piece of string around the base of the finger, mark where it overlaps, and measure the length in millimetres. That is your circumference — match it in the chart.
3. Ask us
Not sure? Contact us with your measurement and we will confirm the size before we make your ring.

Tips for an accurate fit
- Measure at the end of the day, when fingers are at their largest.
- Measure two or three times and take the average.
- If you are between sizes, choose the larger one — especially for wider bands.
- Your dominant hand is usually about half a size larger.
- Need a size outside 5–9? Ask us before ordering and we'll tell you what's possible.
