The most common ring sizes for women are between 6 and 8, while for men, it's between 8 and 10.

  2. Check the product description on Costco's website or in-store to confirm the ring size.
  3. If you're unsure, consider purchasing an adjustable ring or a ring with a slightly larger size that you can have resized by a professional jeweler.
