Ring Size Guide

It is critical to select the correct ring size for your purchase, and we understand that making sure your wedding ring is a perfect fit can sometimes be half the battle. Our professional and passionate team is here to help you determine what size ring will comfortably fit your finger and deliver a complete ring purchasing experience. We provide several ring sizing tools/guides to help you get the correct ring size, but we also recommend having the ring size checked by a local jeweler when possible.

Helpful Advice:

1. Our dominant hand is usually slightly larger than the other.

2. Your fingers may be slightly swollen on hot days.

3. Your fingers may be slightly smaller on cold days.

4. Wider rings will feel more snug.

5. Thinner rings will feel more comfortable.

6. If in doubt, the most common sizes are M-N/6-6.5.

You can send us photos of her hand, and we will try to estimate the size of her fingers based on the photos.

Suggestions to ensure the perfect fit:

  • Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle.

  • Finger size changes depending on the time of day and the weather. For best results measure your finger size:

    • At the end of the day and when your fingers are warm (Fingers are smaller in the early morning and when cold.)

    • Measure finger size 3 to 4 times to eliminate an erroneous reading.

  • Avoid using string or paper to measure ring size as these materials can stretch or twist, yielding an inaccurate measurement

  • When two sizes seem to fit: If you hesitate between two sizes, always go with the larger one.


After you have received your order, if you need it resized, simply contact us and we will be happy to assist you. There will be a small sizing fee of $50/ring. (After the returns period expires, ring sizing is $100/ring). Ring sizing typically takes about 1-2 week.

If you need to change your ring size after placing your order but before it ships, there will not be a fee but it may delay your order.

We don't offer ring sizing if the ring was not purchased directly from our company.

Re-sizing Process

Our jewelers do not stretch rings, but instead will add precious metal when increasing the size. The band is then laser welded back together and polished for a near seamless finish. Finally, the side stones are checked to ensure they are secure in their respective settings. Re-sizing a ring typically takes about 1-2 week from when we receive the package.

In case you are unsure of the correct ring size and plan to have it re-sized by a local jeweler once received, it is easier to size up a ring with side stones than it is to size a ring down as the stones can become loose.

Ring Size Chart FAQs:

What is the typical size of a woman's ring? The average ring size for women varies greatly from person to person, but most women fall into one of three categories: small: I-M, medium: N-Q, and large: R-U. If you want to know the average ring size of a loved one, click the 'Find my ring size' button above or contact us for more information.

Are ring sizes standard? Rings are measured on a universal scale, but each country has its ring-sizing system. In the United Kingdom and Australia, for example, letters are used to determine ring size, whereas, in the United States, numbers are used. Keep in mind that we use UK/Australian letter sizing when placing orders. To determine and convert ring sizes, please see the chart above.

Can a ring be resized down? Rings can be resized. Standard ring sizes are available with most rings at Diamond Lab, and any other size can be resized at an additional cost. Please review the sizing information for each product.

Can you make a ring larger? Rings can be resized in a variety of ways depending on whether they are too big or too small. It should be noted, however, that each ring is unique. Resizing a ring of more than two sizes can cause stress in both directions. Please keep in mind that if the ring was not purchased directly from our company, ring sizing is not available.
