Ring Size Guide
How to measure your ring size
- Cut a thin strip of paper
- Wrap it snugly around the finger
- Mark the point where the paper overlaps
- Lay the strip flat against a ruler & measure the length in millimeters. This is your finger's circumference!
- Match your measurement to the chart to determine your Good Lucky ring size

Between sizes? We generally recommend sizing up. Finger size can fluctuate throughout the day due to temperature, activity, and hydration.
For the most accurate fit, measure at the end of the day when fingers tend to be at their largest. Avoid measuring when your hands are especially cold, as fingers can temporarily shrink.
