Finding the perfect ring size - step by step

Method 1: Measure the existing ring

  1. Choose a ring that fits perfectly
  2. Measure the inner diameter with a caliper or ruler
  3. Compare the diameter with the ring size chart
  4. For online orders: Enter the measured diameter in the shopping cart

Method 2: Measure at home

What you need:
  • A tape measure or a strip of paper
  • A pair of scissors
  • A ballpoint pen

Measuring instructions:
  1. Wrap a strip of paper tightly around the finger on which you want to wear the ring.
  2. Mark the point where the paper strip overlaps.
  3. Measure the length of the paper strip with a tape measure or ruler.

Compare the length with the official ring size chart.

Method 3: Professional measurement

Recommended options:
  • Have your ring size measured free of charge at a jewelry store
  • Use ring sizers that jewelers use
  • Order a free ring sizer online

Important tips:

  • Measure your finger in the late afternoon (fingers are then at their largest)
  • Consider the width of the ring
  • For rings with a wide band, a slightly larger ring size is recommended
  • Make sure it fits comfortably: not too tight, not too loose

Avoid common mistakes:

  • Do not measure directly after exercise or in very cold temperatures.
  • Don't rely on someone else's ring size chart.
  • If in doubt, seek professional advice
