Is size 10 right for you?
1
Check the band width
If the ring band is wider than 6 mm, order half a size up from 10. Wide bands sit higher on the knuckle and feel tighter than the measurement suggests.
2
Measure at the right temperature
Fingers shrink in the cold and swell in heat. Confirm the reading with warm hands at the end of the day, when your fingers are at their largest.
3
Clear the knuckle first
The ring has to pass over your knuckle before it can rest at the base. If your knuckle is noticeably wider, size up from 10 and consider a comfort-fit band.
