Ring Width and Ring Sizing Guide for Men and Women

"How Do I Know What Ring Width & Size To Buy?" in 3 Easy Steps

If you have any questions that aren't answered here, feel free to call us Monday- Friday 9AM - 5PM Eastern Time and speak with a sizing specialist: 1-800-965-3069

1. First decide which width you like:

The width you choose is really just a matter of personal visual preference & physical comfort, but you'll need to know that in order to determine your size. Our widths range from a slim 2mm to a bold 20mm. Women often choose either a 2mm or 4mm band, while men most often prefer 6mm or 8mm. But there is no "rule" you have to follow. Pick the width that conveys the look you want. If you are a right-brained creative here are some mages on both male and female hands to help you visualize:
If you are a left-brained math lover, here are simple conversions of our ring widths from millimeters to inches.

2mm = 1/16 inch
4mm = 1/8 inch
5mm=3/16 inch
6mm =Just under 1/4 inch
7mm = Just over 1/4 inch
8mm = 5/16 inch
10mm = Just over 3/8 inch
12mm = Just under 1/2 inch
20mm = Just under 13/16 inch

And finally here is another visual guide for those of you who are both right and left brained!

An easy rule of thumb is that a nickel is not quite 2mm wide. If you happen to have a nickel laying around, pick it up - and you have roughly a 2mm visual. Stack 3 together and you can see approximately what a 6mm ring would look like on your hand.

2. What size do I need?

First determine what width ring you want (see above).

Second, check the product description on any of our ring web pages under "BAND" to see if it is a Comfort Fit or Standard Fit.

Third....the ABSOLUTE BEST WAY to determine your size is to be either measured by a jeweler or to take a ring that already fits you to a jeweler and have them tell you what size it is. Be sure to tell them the width you are ordering and whether or not it is a Comfort or Standard Fit band.

Many of our rings are built with Comfort Fit sizing. But most jewelers use Standard Fit sizers (which are for rings with flat interiors) so keep that in mind if you have been sized by a jeweler. In Comfort Fit, the interior side/surface of the ring is not flat, but is actually domed which gives it a slight, rounded curve. This minimizes the area of contact between your finger and the ring's surface making it more comfortable to wear... while still keeping the ring securely around your finger. Here is a cross section view of a Comfort Fit ring:

If you already know your normal Standard Fit ring size, we'd recommend that when purchasing a Comfort Fit ring from our store, you order half a size smaller (unless you are ordering an 8mm width or larger). If you are normally a size 8.0 on a standard sizer, a 7.5 would be your best choice. Similarly, if you're a 10.5, go ahead and order a 10. Please Note: If you are ordering a ring in an 8mm or larger width, you may not need this adjustment down in size due to the larger surface area of a bigger ring. In fact, very large widths (12mm-20mm) may require a increase above your normal ring size. This is to accommodate the larger ring sliding over your knuckle.

If being sized by a jeweler is not an option, you can purchase our Adjustable Ring Sizer here. It's not perfect, but it is the next best thing!

3. Don't worry ..... We are always happy to help!
