Ring Size Guide

Ring Size Guide

Shopping jewelry online can be very exciting, but what happens when you don't know your ring size?

The next time you are near a local jewelry store, it never hurts to stop by and ask them to measure your size properly. But until then, let's explore how you can easily and accurately find your perfect fit right from the comfort of your home!

Important Note: All ring sizes listed on our website are US sizes. If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want the ring to slide over your knuckle comfortably, but not be too loose to shift around.

Method 1: Measure an Existing Ring

If you already own a ring that fits you like a glove, measuring its inner diameter is the most reliable way to find your size.

  1. Place your ring on a flat surface.

  2. Position a flat ruler across the center of the ring.

  3. Measure the inside distance (Internal Diameter) from one inner edge to the other in millimeters as accurately as possible.

  4. Use our international size chart to convert the inside diameter to your US size.

Method 2: The Ribbon + Ruler Method

If you don't have a ring available, you can easily measure the circumference (perimeter) of your finger using a simple ribbon or a strip of paper.

  1. Wrap it: Wrap a non-elastic ribbon or paper strip around the base of the finger you want to measure. Make sure it sits straight and comfortably tight.

  2. Mark it: Use a pen to mark the exact spot where the ribbon overlaps, completing a full circle.

  3. Measure it: Lay the ribbon flat against a ruler and measure the length in millimeters to find your circumference.

  4. (Optional Math Trick): If you divide this measured circumference by 3.14, you will instantly get your internal diameter!

  5. Match your millimeters with our chart to find your US size.

Method 3: Use a Ring Sizer

Don't trust your measuring skills enough? Opting for a plastic Ring Sizer is the absolute best option to guarantee a perfect fit for any finger you are shopping for.

Need a Custom or Half Size?

We want your Odotis ring to fit you perfectly. If you require a customized half or quarter size (such as 5.25, 5.75, 6.5, etc.) that is not available in the drop-down menu, you can easily request it!

Simply place your order and leave us a note with your exact desired size in the ORDER NOTES section at the checkout page.

Quick Tips for Accuracy:

  • Temperature matters: Make sure your hands are at a normal, warm body temperature. Fingers tend to shrink when cold and expand when hot (especially during summer).

  • When in doubt, size up: If your measurement falls between two sizes, we always recommend choosing the larger size for a more comfortable fit.
