Measure at Room Temperature
Fingers naturally expand in warmer weather and shrink when cold. Measure in the evening when hands are at standard resting size.
Consider Band Width
Wider bands (5mm+) fit tighter than delicate stacking bands. We suggest sizing up by a quarter or half size for substantial silhouettes.
Knuckle Clearance
If your knuckle is noticeably larger than the base of your finger, choose a size that slides snugly over the knuckle with gentle resistance.
