Pro Ring Fitting Tips
- Measure your finger in the evening, as fingers naturally swell slightly during the day.
- Cold fingers appear smaller, so avoid measuring in cold environments.
- If you choose a wide-band ring, we recommend ordering half a size up for comfort.
- When between two sizes, always pick the larger size.
