If you're unsure of your ring size, we recommend visiting our jewelry store for a professional measurement.
You can also measure your ring size at home. Here are a few simple methods to help you do so:
Measure Your Finger
-
Use a flexible measuring tape or a length of string.
-
Wrap it around the finger you plan to wear your ring on. If you’re creating a ring stack, consider exactly where on your finger the ring will sit.
-
If using string, mark the point where the ends meet. Lay the string flat and measure the marked length in millimeters.
-
Compare your measurement to the size chart to determine your ring size.
-
If you fall between sizes, choose the larger size for the most comfortable fit.
Measure an Existing Ring
-
Select a ring that already fits the intended finger comfortably.
-
Measure the interior diameter of the ring across its widest point in millimeters.
- The ring’s diameter in millimeters corresponds to its size. For example, if the ring’s inner diameter is 16 mm, the ring size will be 16.
-
If the diameter falls between two sizes, for example 18.8 mm, it is recommended to choose the next larger size—in this case, 19.

*Please note: Manual sizing methods—such as measuring your finger at home—can lead to slight inaccuracies. Please read our resizing policy below.
Resizing Policy
We will work closely with our jewelry designers to make sure that you are satisfied with your purchase. Items can be altered according to your specifications but please note that additional fees and additional delivery time may apply. We cannot, however, offer resizing on a few fine jewellery designs. Please contact us if you have any questions about a particular ring.
Rings made to order
If you cannot find a ring of your size and/or a ring you like cannot be resized, sometimes it’s possible to make a new ring if requested. Therefore, you are welcome to get in touch to discuss your requirements and we’ll do our best to accommodate them.
For more information, please email us on info@miutto.com or call our customer service at +370 680 85111.
