Guide to Selecting the Right Wedding Band Size


When you find the perfect wedding band, you want to ensure it’s the right size. We created a wedding band sizing guide to help you determine the right wedding band size, select the correct width and understand the resizing process.

How to Determine Wedding Band Size?

Consider using more than one ring size method for a "measure twice, cut once" approach to ring sizing. It’s much less trouble if you carefully measure your wedding band size initially to avoid resizing in the future. Here are some helpful tips to determine your ring size:

  • Measure another ring that fits the same finger: Take one of your other rings and compare it to the size chart below to find the approximate fit

  • Use a Paper Strip: Use the paper strip at the bottom of this chart. Cut out the ruler and wrap it around your finger. Ensure it's a snug fit. Use the line demarcations to see what your ring size is.

  • Use string or dental floss: Take a piece of string or floss and wrap it around your finger (but not too tight). Mark the place where the string or floss meets and measure against the With Clarity size guide to get the approximate size.

  • Head into a local jewelry store: Ring sizing is typically free, so there’s no need to feel pressure to buy anything. It’s very common to pop in, get your finger measured with a mandrel in-store, and then finish buying your wedding band online.

Here’s a band size chart for reference and here’s a printable ring sizing guide:

Resizing Rings

Most rings and bands can be resized within a few sizes. While it is typically okay to move a few sizes up or down, try to stay within two finger sizes. Resizing a ring or band any more than two finger sizes can be difficult. The simpler the wedding band, the easier it is to resize.

To make a wedding ring smaller, the jeweler cuts out a piece of the band, forms it back into a perfect circle, and then solders it back together. Once the process is finished, there’s no evidence that the ring was ever cut. Making a ring larger is a more complicated process than making it smaller. It entails the jeweler stretching the metal, and this can only be done up to half a size larger.

To resize a ring larger, the jeweler cuts the band and adds in an extra metal. Then the wedding band is soldered, cleaned and polished. which they will then solder, clean and polish. For example, if your ring has channel settings, it might be necessary to rearrange the stones during the process of resizing the ring.

We’re here to help if your wedding band doesn’t fit! Each With Clarity customer is allowed one free resizing as long as it is done within 30 days of the ring purchase.

Challenging Rings to Resize

While most rings can be resized, there are some wedding bands that are more challenging. For example, an eternity band that has gemstones all around the band cannot be resized because the process will destroy. In addition, some metals can’t be resized. Rose gold will crack if it gets resized.

An engraving will have to be redone post resizing as the metal is heated causing the engraving to alter in appearance. Post a resizing, any ring or wedding band will be reengraved to mimic the original look.

Wedding Band Width

While many focus on the size of the wedding band, it’s also important to consider the width of the wedding bands. You don’t want to find the perfect wedding band and be disappointed with the width on your finger. The width indicates how comfortable a ring is to wear and also impacts the look of the ring–whether it’s a thicker ring or a more lean version.

The measurement units of the width of a ring are in millimeters as well, generally, the width of a ring will start from 1.5 millimeters. Width depends on the size of the hands and personal preference. Most women’s wedding band rings are between 1.5 and 4 millimeters in width. Most men’s wedding band rings are between 5 and 8 millimeters.

Here are some examples so you can view different wedding band widths.
