Important tips
- Measure your finger at the end of the day, when size is most stable.
- In cold weather fingers shrink; in warm weather they expand slightly.
- For wide or thick bands, choose half a size up.
- If you are between two sizes, go with the larger size for comfort.
- For bulk OEM orders, tell us your market’s common size range—we can help recommend size distribution.
