Our Finger-sizer (included in our Home Try On kit) works just like a belt. Just wrap it around your ring finger and slide the end through the buckle to form a ring shape. Adjust so that it’s slightly snug on your finger, but can still slide over your knuckle with a tiny bit of effort. When you’ve found a good fit, read off the size next to the arrow.
A few quick tips:
1. If you're in between on sizes, size up. You're always better off slightly big than too small when it comes to wedding bands.
2. Measure your fingers at the end of the day, when they're at their largest.
3. Cold weather can shrink your fingers up to 1/2 size, so make sure they're warm and fuzzy.
4. Alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
