Moon Ring Size Guide

SIZE GUIDE

What is ring size? Ring size refers to the circumference or diameter of your finger, which helps you choose the perfect ring size. All measurements are expressed in millimeters.

The ideal finger size is one that allows the jewelry to pass through your finger joint with light to moderate resistance.

The jewelry should be easy to put on and rotate around the finger without being too tight. If it's too tight, it could compress the finger. Ideally, it should offer slight resistance when passing over the knuckle, requiring a slight twisting motion to remove.

You can adjust the size from a half size to a full size according to your preferences, especially if you know your fingers tend to swell.

To find out your size, we invite you to download our printable paper guide.

This paper version makes it easy to measure an existing piece of jewelry by placing a ring belonging to the recipient on "guide rings" in order to find the perfect match and, therefore, the corresponding size.

Please note, make sure you measure a piece of jewelry worn on the same finger as the one where you wish to wear our ring.

TAKE THE MEASUREMENTS DIRECTLY ON YOUR FINGER

Step 1: Get yourself some light-colored string and a dark marker.

Step 2: Wrap the string around the finger that will wear the ring, at the point where it will be positioned.

Step 3: Mark with the marker the place where the two ends of the string cross (make sure that the ink is visible on both parts of the string).

Step 4: Using a ruler, measure the distance in millimeters between the two marks. This measurement corresponds to your ring size.
(Example: 55 mm = size 55)

TAKE ONE OF YOUR RINGS AS A REFERENCE

To find your ring size, you can also measure it with a ruler. Lay one of your rings flat and measure the distance in millimeters between the two inner edges . This number corresponds to the ring's diameter. Then, consult the table below to convert this diameter into a ring size.
