Moon Ring Size Guide
What is finger size? Finger size corresponds to the measurement of your finger's circumference or diameter, which allows you to choose the ring size that will fit you perfectly. All measurements are expressed in millimeters.
The ideal finger size is one that allows the piece of jewelry to pass over your knuckle with light to moderate resistance.
The jewelry should be able to be put on without difficulty and rotate around the finger without being excessively tight. If it is too tight, it could compress the finger. Ideally, it should offer slight resistance when passing over the knuckle, requiring a gentle twisting motion to be removed.
You can adjust the size by half a size or a full size depending on your preferences, especially if you know your fingers tend to swell.
To find 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 over "guide rings" to find the perfect match and, thus, the corresponding size.
Attention: ensure that you measure a piece of jewelry worn on the same finger as the one where you wish to wear our ring.
TAKE MEASUREMENTS DIRECTLY ON YOUR FINGER
Step 1: Get a light-colored piece of string and a dark marker.
Step 2: Wrap the string around the finger that will wear the ring, at the spot where it will be positioned.
Step 3: Mark the place where the two ends of the string cross with the marker (make sure the ink is visible on both parts of the string).
Step 4: Using a ruler, measure the distance between the two marks in millimeters. This measurement corresponds to your ring size.
(Example: 55 mm = size 55)
USE ONE OF YOUR RINGS AS A REFERENCE
To determine your size, you can also measure your ring size 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 diameter of the ring. Then consult the table below to convert this diameter into a ring size.
