FAQ

Does ring size change with weight?

Yes, ring size changes with increasing weight in most cases. Weight increase may change body shape, hand shape, and finger shape. It makes them thicker. So, one may require a larger-sized ring compared to the previous one.

Why do my rings sometimes not fit?

It’s natural for your rings’ sizes to fluctuate with the seasons. So, finger swelling in the summer is a common experience worldwide because of the increased water retention we experience in the warmer months. Even a slight swelling might significantly alter fitting of your rings.

Do same-aged men and women have the same ring size? 

A man has a larger body structure compared to a woman. Due to this, a significant difference in body frame between men and women is clearly noticeable. Different body frame shapes the fingers differently. That is why, though a man and woman are the same age, their ring size may not be the same.
