How to Measure Your Ring Size

Method 1: Using a Ring Sizer

Visit any Zamanix boutique for a professional fitting with our ring sizer tool. This is the most accurate method to determine your ring size.

Method 2: Using an Existing Ring

Measure the internal diameter of a ring that fits well:
- Place the ring on a piece of paper
- Draw circles inside and outside the ring
- Measure the internal diameter in millimeters
- Compare with our size chart below

Method 3: String Method

1. Wrap a string around your finger
2. Mark where the string overlaps
3. Measure the length in millimeters
4. Use our conversion chart to find your size

Tips for Accurate Measurement

  • Measure at the end of the day when your fingers are at their largest
  • Avoid measuring when your hands are cold
  • Consider seasonal changes in finger size
  • Account for wide bands needing a slightly larger size
  • If between sizes, choose the larger size
