Tools Needed: Ring that fits perfectly + printer + ruler
Step-by-Step:
1. Print ring sizer chart (100% scale)
2. Place existing ring over circles
3. Find exact match (inner edge alignment)
4. Note US size (most common: 6-8 women, 9-11 men)
Pro Tip: Use ring worn on target finger; avoid “sometimes fits” rings.
