Found the perfect ring but need help determining your or someone else's ring size? We've created a Ring Size Guide, and a few tips on how to get your ring size just right. 

This guide offers two methods of measuring for your ring size. If you already own a ring, simply measure the inside diameter of the ring and match the size to the chart. If you don't have a ring, then measure the intended ring finger and match the measurement to the chart.


  1. If using a ring to measure, ensure that you choose a ring that fits the intended ring finger.
  2. If measuring a finger, measure towards the end of the day when the finger is warm. When your fingers are cold there can be up to half a size difference.
  3. Keep in mind that rings with a thicker band feel tighter than those that have a thinner band. If you're measuring a thin band, and intend to buy a thicker band, look to buy a full ring size bigger.
