How to Figure Out Your Ring Size

Posted by Brent Gray on 9/28/2015

Knowing your exact ring size, especially when ordering online, is important. There’s nothing more frustrating than receiving your dream ring only to find out that it doesn’t quite fit. Most online ring resellers will allow you to exchange your ring for another size, but who wants to hassle with that?

The very best way to know your correct ring size is to go to a local jewelry store and ask them to measure your ring size for you. Any jewelry store will gladly do that for you. And there are jewelry departments in just about every Walmart, Costco, Target, or other department store or shopping mall in the country, so it’s usually not a big deal to do that. Sometimes, however, that’s just not possible and an alternative method is needed.

There are two other methods that we recommend for determining your ring size from home. Although we can’t take credit for it, we think Option #1 below is much better (more accurate) than Option #2, but you have to already have a ring on hand (no pun intended!) that is the size you want.

Here are two ways to determine your ring size from home:

Option #1: If you already have another ring that fits:

Use this handy (and accurate ) online tool to figure out your ring size. Just click this link or copy and paste it into your browser: You will need the ring that fits your finger and a standard plastic credit card. (Your credit card is just used as a size reference, not for payment.)

Option #2: If you DON'T already have a ring that fits:

  1. Cut a strip of paper approximately 1/2" wide and 5” long (Hint: Don’t use string to measure the circumference of your finger. String tends to easily stretch (more than you think) and can give you a false reading.)
  2. Wrap the paper strip around the knuckle of the finger you are measuring (The ring must be sized large enough to be able to slip on and off over the knuckle)
  3. Mark the paper with a pen where it overlaps
  4. Measure the distance from the edge of the paper strip to the mark; this is the inside circumference (Helpful Tip: measure in millimeters for a more accurate measurement)
  5. Check your measurement against the Inside Circumference on this International Ring Size Conversion Chart to determine your ring size
  6. If the measurement falls in between two sizes, we recommend that you choose the larger size

Either of the above methods work, although you’ll soon find that how tightly you pull the strip of paper in Option #2 can easily give you different results. You might want to try both methods and compare the results, but if possible, visit your local jeweler to get the most accurate measurement.

Happy shopping!
