Continue ShoppingClothes and shoes are measured differently for men and women. However, men's and women's ring size is measured the same. Ring size is measured on a ring mandrel by the inner diameter of the band. When measured, a men's ring size nine measures the same as a women's ring size nine.
Important note: Ring bands will vary on the width. A wider band may require a larger size ring. The inner diameter might be the same, but a wider band will feel tight due to the amount of metal in contact with your finger.
If you wear a size 7 in a thin 1.5mm wide band, a size 7 in an 8mm wide band may feel tight even knowing both are a size 7. We recommend a larger half or full ring size if you shift from a thin band to a more wide band.
We have an easy exchange process if you order the wrong inner diameter. If you do not know your ring size, we have a quick finger sizing tool here.
