Method 1: Measure an Existing Ring
If you already own a ring that fits the intended finger:
- Place the ring on a flat surface
- Measure the inner diameter (in mm) using a ruler
- Match the measurement with the size chart below
Method 2: Measure Your Finger
Using a strip of paper or thread:
- Wrap it around the base of your finger
- Mark where it overlaps
- Measure the length (in mm)
- Compare with the circumference in the chart
💡 Tip: Measure your finger at the end of the day when it’s slightly larger for better accuracy.
