Measure your finger
- Wrap a strip of paper around your finger where you'd like your ring to be.
- Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit.
- Mark the spot where the paper meets and measure the distance with a ruler (mm).
- The measured distance(mm) is the circumference of your ring, please use the below chart to know your ring size

Determining what FORO ring you should order
Narrow / band rings should fit snugly at the base of the finger but also wide enough to fit the widest part of the finger. (e.g.: knuckle)
Wide Rings (6 mm + wide )should be worn a bit looser than narrow / band rings. It is recommended to add one size to accommodate for extra width.
Please Note: If your knuckle is larger than the base of your finger
- Measure your knuckle size
- Measure your Ring Size i.e base of the finger
- Pick a size between the Two
A few notes to consider
- Measure your fingers at the end of the day when they’re at their largest
- Cold weather can shrink your fingers up to half a size, so make sure they’re warm
- . Lastly, alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
