Determining the Accurate Ring Size

When it comes to picking out the perfect ring, size definitely matters. But how do you determine your loved one’s ring size if you’re unsure? On top of that, estimating the right ring size becomes more significant when you try to choose the perfect-sized ring without letting her know.  

Average Ring Size of a Man and a Women

If you are completely unfamiliar with the ring size for your loved one, the safest choice will be to consider the average ring size. Okay, let’s get to know about the average ring size for a man and a woman.

For Woman


Women’s average ring size typically ranges from a size 4 to a size 9. But size six is considered an average ring size for a woman. This ring size is based on the USA standard ring size.

In the UK, this size is “L,” and in Europe, the equivalent ring size is “54”. The diameter of the size 6 ring is 16.31 millimeters.  

For Man


On the other hand, men’s rings tend to be larger than women’s. Furthermore, the bands on their items tend to be wider, so buying a size up will usually result in a more comfortable fit.

Depending on the design, men’s rings can be found in sizes 7 – 15 in the USA standard ring size. But, men’s ring sizes typically range from 6 to 12 in the USA standard, where size 10 is considered an average ring size for a man.

In the UK, this size is “T,” and in Europe, the equivalent ring size is “61”. The diameter of the size 10 ring is 19.56 millimeters.

FAQ
s

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.
