Ring Size Guide for EU

When purchasing a ring, it’s essential to know your correct ring size to ensure a perfect fit. The European (EU) ring sizing system is based on the circumference of the ring in millimeters. Here is a guide to help you find your EU ring size:

Steps to Measure Your Ring Size:

  1. Using a Ring You Already Own:
    • Measure the Diameter: Find a ring that fits the intended finger well. Measure the inside diameter of the ring in millimeters. Make sure to measure across the center of the ring.
    • Refer to the Size Chart: Use the diameter measurement to find the corresponding EU ring size in the chart below.
    • Use a Ring Size App: There are multiple apps available where you can place your existing ring on the screen of your phone and adjust the circle on the screen to match the ring’s size. The app will then show you the ring size.
  2. Using a String or Strip of Paper:
    • Wrap Around the Finger: Wrap a piece of string or a thin strip of paper around the base of the intended finger. Ensure it’s snug but not too tight.
    • Mark and Measure: Mark where the string or paper meets and then measure the length with a ruler in millimeters. This measurement is the circumference of your finger.
    • Refer to the Size Chart: Use the circumference measurement to find the corresponding EU ring size in the chart below.

  • Ensure the ring size fits comfortably over the knuckle without being too tight.
