Ring Size Guide

Finding your perfect ring size is simple and ensures that your jewelry fits comfortably and looks stunning. Follow our step-by-step guide to measure your ring size at home or find the perfect fit as a gift.

How to Measure Your Ring Size at Home

  • Option 1: Measure a Ring You Already Own

    1. Choose a ring that fits the intended finger: Ensure it’s a similar style to the ring you’re purchasing (e.g., wider bands may fit more snugly).
    2. Measure the diameter: Place the ring on a ruler and measure the internal diameter (in mm).
    3. Match your measurement to the size chart below: Example: If your ring measures 16.5 mm in diameter, your size is US 6.

  • Option 2: Use a String or Paper Strip

    1. Cut a strip of paper or use a piece of string: The strip should be about 1 cm wide.
    2. Wrap it around your finger: Wrap it snugly around the base of your finger, but not too tight.
    3. Mark where the ends meet: Use a pen to mark the overlap point on the string or paper.
    4. Measure the length: Lay the string or paper flat and measure the length in millimeters.
    5. Find your size on the chart below: Example: If your measurement is 52 mm, your size is US 6.

  • Pro Tips for Accuracy

    • Measure your finger at the end of the day when it’s at its largest.
    • Avoid measuring cold fingers, as they can shrink slightly.
    • Take multiple measurements for the most accurate result.
