  2. Our ring size for the dominant hand tend to be slightly bigger, be sure to get the measurement of the finger on the correct side!
  3. The width of the band may affect the ring size that is fitting. A ring with a wider width may be snugger compared to a ring with thinner width.

Do note that some rings may have certain limitations in how much it can be resized. Do let us know your intention of resizing and we will be happy to offer the best solution to you.
