1. Use a Ring You Already Own
If you have a ring that fits the desired finger well:
- Measure the inside diameter in millimeters.
- Match it to a size using our chart below.
Note: Ring sizing may vary between brands. Always go by precise measurements rather than size labels.
2. Measure Your Finger Directly
If you don’t have a ring to measure:
- Cut a thin strip of paper or use a piece of string.
- Wrap it around the base of your finger snugly.
- Mark where it overlaps.
- Measure the marked length in millimeters.
- Use the chart below to find your ring size.
Tips for Best Accuracy
- Measure at the end of the day when your fingers are at their largest.
- Avoid measuring when your hands are cold, as your fingers may be smaller.
- If you're between sizes, choose the larger one for a more comfortable fit.
