"Could Common Sense be Challenged? Did You Know 'Ring Sizes' Vary by Store?"

【Surprising】It Seems Ring Sizes Can Vary by Store!?

The size of a ring is determined by the diameter of the circle (band) in sizes like 【1, 2】.

For example, a size 7 ring is set at 15.0mm, and this is something many people might think is a common standard across any jewelry store. However, the truth is that ring sizes can actually differ from store to store...!

Sizes Differ Between Domestic and International Brands!

You might wonder, “How can the sizes differ among stores when ring sizes are standardized?” The concept of “size number” is unique to Japan. International brands use different metrics to determine size.

Therefore, someone who fits perfectly into a Japanese size 7 would likely wear either a US size 4 or 4.5. They would choose a “close size” rather than an exact match for 7.

Furthermore, the unit of measurement may not be in centimeters but in inches, indicating that there isn't a perfect compatibility.

Of course, this isn't just a story limited to Japan and the US; sizes are expressed differently in countries like the UK and Italy as well.

Indeed, when you think about it, clothing and shoes also have varying size standards depending on the country or manufacturer. It seems to be similar in this regard.

When Do Problems Arise?

Generally, when you go to a jewelry store to buy a ring, you try it on and check the size, so whether it’s a Japanese or international size is not usually an issue.

But when does it become a problem...?

For instance, when a boyfriend surprises his girlfriend by buying a ring.

Him: “What size ring do you wear?”

Her: “Size 7!”

In what seems like a casual conversation, the boyfriend finds out his girlfriend's ring size, purchases a surprise ring, and proposes...!!!

This is a pretty conceivable scenario, but if he buys from an international brand and it doesn’t fit...

That would be a tragedy.

After all, a man wouldn't necessarily know that size standards differ by country.

Romantic proposals are certainly admirable, but it's a point worth noting to be cautious about!

Always make sure to get measured and try on rings at the brand you are buying from.

If there isn't a sample ring in the appropriate size or if you absolutely can't try it on, buying a larger size can provide peace of mind.

Additionally, if you're torn between “somewhat smaller” and “somewhat larger” sizes, it's recommended to opt for the “somewhat larger” size.

Fingers tend to swell quite easily, so while it may fit normally during the day, it might not fit at night, and stories of hands swelling during pregnancy and childbirth causing rings not to fit can often be heard.

Therefore, if you're uncertain about size, choose the larger size! ♩

Also, it's reassuring if the brand offers a service for future size exchanges.

Choose the Perfect Sized Ring ♩

Since the way sizes are expressed differs between Japanese and international brands, it’s important to be careful.

It would be sad if wedding bands or engagement rings meant to symbolize eternal love didn't fit or were too loose!

When selecting a ring:

① Always try it on and measure at the store you intend to buy from.

② If in doubt, choose the larger size.

③ Select a store that allows size exchanges.

Keep these three points in mind and find your destined ring! ♡
