Option 1: Measure a ring you own
Lay a ring that fits the finger you want on a ruler. Measure straight across the inside, edge to edge (inner diameter). Match the measurement to the chart below.

Tips
- Measure at the end of the day, when fingers are a little bigger.
- Between two sizes? Go with the larger one.
- Wide bands fit snugger, so size up a half size for wide styles.
- Many of our rings are adjustable. Check the product description.
