Finding the Right Finger Size for your Wedding Ring or Anniversary Band

A beautiful wedding ring or anniversary band looks and feels its best when it is sized correctly to your finger. The most accurate method in determining your correct finger size is having a local jeweler measure it. We suggest doing this before purchasing any wedding ring. A second option is detailed below and is suggested only as a guideline; it should not be used as the final determination of your finger size.

Follow the four steps below as a guideline to determining your finger size. Note that ring sizes can increase or decrease based on the climate, temperature and your level of activity. We recommend measuring your finger at the end of the day in a comfortable room temperature to get the most accurate ring size.
  1. Wrap a thin paper strip or string around the base of your finger. It should fit snugly but still be able to slip over your knuckle. However, don't size it to your knuckle. The ring size will be too large.
  2. Using a pen, mark the paper or string where it overlaps to form a complete circle.
  3. Measure the length of the section of paper or string where it overlaps around the finger. Use a ruler with millimeters. If you don't have one, the ring size chart includes a helpful conversion guide.
  4. Compare your measurement with the ring size chart below to determine your size.
All rings are available in custom finger sizes, whether it’s smaller or larger than the 4-12 listed on our website. Please contact service@eternityweddingbands.com if you would like an alternate finger size.

If you are between sizes and unsure of which ring size to purchase, choose the smaller ring size as there is much less possible damage to the ring when enlarging it by ¼ or ½ finger size than there is when decreasing it to a smaller finger size. Do not order the smaller ring size, however, if it is too snug or tight of a fit. You always want the ring to be able to come off with a slight tug.

We want you to be 100% satisfied with your purchase. If you receive your wedding ring or anniversary band and it is not the right fit, you may return or exchange it for a different finger size. Please see our Return &Exchange Policy for more details.

Exchanging your Ring for a Different Size?...
If you need to resize your ring by ½ or ¼ finger size, we ask that you consider the following: Many times a new ring can take a few days to feel comfortable on your finger. Your fingers may actually change size throughout the day, depending on the weather and temperature, and may fit more comfortably at different times of the day. Due to these factors, we recommend that you wear the ring for approximately 48 hours before determining whether or not to resize the ring.

With our experience we find that after wearing the ring for 48 hours many customers determine that they do not need to resize their ring, and this trial period saved them shipping fees and the process of exchanging the ring only to realize it was just fine in the first place.
