Measuring Tips
- Measure at the end of the day when your fingers are largest.
- Cold weather can make your fingers slightly smaller.
- Measure two or three times for better accuracy.
- Use a non-stretch paper strip.
Between Sizes?
If your measurement falls between two sizes, choose the larger size for a more comfortable fit.
Wider rings may feel tighter than narrow rings, so consider going up half a size.
