Tear up a strip of paper
Wrap the paper around your finger, make sure it's wrapped nice and tight and mark the spot where it meets.
Measure the distance with a ruler in (mm), that’s your circumference.
PRO TIPS FOR MEASURING
- Measure at the end of day
Because fingers swell during the day, it's best to measure in the evening.
- Thick bands are uncomfortable.
Be aware that bigger rings feel more constrictive than thinner ones. For thicker bands, you may wish to go up a size.
- Hands should be warm
The cold might cause your fingers to shrink and hence your measures to diminish.
