How to Measure Your Finger Size
To find your ring size, simply use an existing ring that fits the desired finger comfortably. Measure the internal diameter (the space inside the ring) in millimeters. Once you have this measurement, refer to the size chart below to determine your corresponding ring size.
Keep in mind
Bands with a wider surface area tend to fit more snugly than those with a thinner width and profile. If you’re choosing a wider ring, you may want to size up slightly for a more comfortable fit.
