We offer ring sizes in every quarter size from 3 to 12.75, ensuring the perfect fit for every finger.


How to Measure Your Ring Size at Home

We offer three simple, accurate methods for measuring your ring size from the comfort of your home. No jeweler required.

Method 1: Measure a Ring That Fits

  1. Select a ring that fits the intended finger.
  2. Measure the internal diameter of the ring at the very center in millimeters.
  3. Use our ring size conversion chart to find your corresponding size.

Tip: Ensure the ring has a similar band style to the one you plan to buy, as wider bands can fit more snugly.

Method 2: String or Paper Strip Technique

  1. Cut a thin strip of paper or use a non-stretchy string.
  2. Wrap it around the base of the finger you plan to wear the ring on.
  3. Mark the point where the ends meet.
  4. Measure the length with a ruler (in millimeters).
  5. Use the chart below to convert your measurement to a ring size.

Tip: Measure your finger at the end of the day when it is at its largest. Avoid measuring when your hands are cold

Frequently Asked Questions

How do I know if a ring fits properly?
A properly fitted ring should slide on easily and come off with slight resistance over the knuckle. It should feel snug but never tight.

What if I'm between two sizes?
We recommend sizing up for comfort, especially for rings with wide bands.

Can I resize my Yoona ring?
Many of our designs can be resized. Contact us to inquire about resizing services.

Do all fingers have the same size?
No, each finger is unique. Measure the exact finger (and hand) you'll wear the ring on.
