Ring size guide
Find your ring size
Two easy ways to measure at home, and a chart from Indian sizes to millimetres and US sizes.
Measure a ring you already wear
Pick a ring that fits the finger you're buying for. Measure straight across the inside, edge to edge, in millimetres. That's the inside diameter: find it in the chart.
Measure your finger
- Wrap a thin strip of paper or thread round the base of your finger.
- Mark where it meets, then lay it flat against a ruler.
- That length is your inside circumference. Find it in the chart.
Tips for the right fit
- Measure at the end of the day, when fingers are at their largest.
- Don't measure when your hands are cold; fingers shrink.
- If a knuckle is wider than the base of your finger, make sure the size will slide over it.
- Between two sizes? Choose the larger one, especially for wide bands.
Sizes in the chart are a close guide. Indian sizes run roughly 40 mm under the inside circumference.
