Sizing Guideline:

• Step One: Choose a thin string or piece of paper, to wrap around your finger.
• Step Two: Wrap the string or paper around the base of your finger. Ensure it is snug but not too tight. Your ring should fit comfortably, so, the string should not dig into your skin.
• Step Three: Using a pen or marker, mark where the string or paper overlaps to form a complete circle around your finger.
• Step Four: Lay the string flat and measure the length from the starting end to the mark you made using a ruler or measuring tape. Record the measurement in millimeters.
• To determine the correct ring size, use this perimeter measurement directly or convert it to the diameter if preferred.
• Tips
  • Measure at the right time, your finger size can change throughout the day due to temperature and activity.
  • Measure your finger at the end of the day when it will most likely be at its largest.
  • To ensure accuracy, repeat the measurement process a few times and use the average size.
