Expert Tips for Accurate Sizing
- Measure your finger at the end of the day when it's at its largest
- Avoid measuring when your hands are cold as fingers shrink in cold temperatures
- Measure the finger you plan to wear the ring on, as each finger can be a different size
- For wider bands, consider going up half a size for comfort
- If between sizes, choose the larger size for comfort
- Measure 3-4 times to ensure consistency and accuracy
