Ring sizing pro tips

To get the best fit for your ring, keep these things in mind:

Don’t shake it off

For a ring to fit comfortably, it should be snug enough to stay on if you shake your hand, but loose enough to just fit over your knuckle.

Leave room for ring stacks

When you pick a place to measure, account for the width of the band and any stacking rings you wear.

Choose where to wear it

Engagement and wedding bands are traditionally worn on the left-hand ring finger, while fashion rings can be worn on any finger (or thumb) on either hand.

Frequently asked questions

If you ordered the wrong ring size, you may be able to exchange it for the right size. If there is not a similar option available in the size you need — or if you ordered a custom ring — Helzberg can resize the ring according to your specifications.

Helzberg offers a broad range of ring sizes to suit the unique needs of our customers. We can also resize rings to ensure a comfortable fit.

Ring sizes are usually based on the inner diameter in millimeters. In the U.S., ring sizes are obtained using a numeric scale based on quarters and half units.

Yes — jewelers use the same size chart for men and women. That said, women generally prefer narrower bands because they tend to have smaller fingers. The average ring size for women is 7 while the average ring size for men is an 10.

The cost of resizing a ring depends on whether you are increasing or decreasing the size. To size down a too-large ring, jewelers can remove a small portion of the shank. To up-size when a ring is too small, they have to cut the shank and add a small amount of metal. The complexity of the ring design, metal, gemstone placement and band shape can also affect the cost. A simple resizing might cost $46 – $180.

With a Helzberg’s Lifetime Care Plan, resizing your ring is free. Sign up when you purchase your next piece of fine jewelry. 

You might be able to get someone’s ring size by borrowing a ring you know fits the right finger and tracing the inside of the shank or taking it to your local Helzberg store. You can try asking a close friend or family member. If you’re extra daring, you might try measuring their finger while they take a nap. Find more ideas for getting someone’s ring size here.
