How to choose your size

2026.08.09

Do you know the perfect ring size for your finger?


Many of you likely own plenty of fashion rings, but perhaps you’ve never actually measured your precise size.


For many people, the first time they discover their ring size is when choosing a made-to-order wedding ring or jewelry for a special anniversary.





A precious ring is something you will wear every day from here on out.

It’s natural to feel a bit anxious about whether you’re choosing the perfect size for your finger.


Today, to help you feel more confident in your choice, we would like to share some tips on how to select your size, as well as recommended ordering methods.




◇POINT 1: Know your finger shape◇



Finger shapes vary from person to person.

Let’s check for the optimal size based on the unique characteristics of your finger.


〈 For those with the largest knuckle 〉


・Your second knuckle is prominent and bony

・The base of your finger is slimmer than the second knuckle


For those with this shape, we recommend a size that allows the ring to "catch" slightly on the second knuckle as it passes over.

If you choose a size that slides over the knuckle too easily, there is a risk that the ring might slip off.

On the other hand, if you choose a size that is too tight at the knuckle, you may feel pain every time you put it on or take it off, which could lead you to stop wearing it, or it may become impossible to remove.

We hope you will consider your lifestyle, such as how often you typically take your rings off, when choosing your size.


〈 For those with the thickest base 〉


・Your knuckles are not very bony

・Your finger tapers from the base toward the fingertip


For those with this shape, we recommend a snug, slightly tighter fit.

If you choose a loose size, there is a risk that the ring will slip off easily.

On the other hand, if you choose a size that is too tight, you may experience pain when your fingers swell or find yourself unable to remove the ring.

Try putting the ring on and making a fist to check for any pressure or pain, and choose a size that feels comfortably fitted.

Please also consider changes in size due to the seasons and your lifestyle to ensure you choose a size you can wear with peace of mind.

 


◇POINT 2: Fluctuations due to swelling◇

Fingers can swell and change size depending on the season, the time of day, and your diet.

When measuring your size, we recommend doing so when your fingers are in a normal, non-swollen state.

Since the way your fingers swell varies from person to person, it is important to consider these personal changes when deciding on a size.

 

〈 Seasons and Temperature 〉

・Hot seasons or environments: Fingers tend to swell and become thicker.

・Cold seasons or environments: Fingers tend to contract and become thinner.

Keep in mind that sizes can fluctuate due to temperature and season, and choose a size that remains comfortable to wear.

 

〈 Time of Day 〉

It is generally said that fingers swell more in the evening, but this varies individually.

There may be a fluctuation of 0.5 to 1 full size throughout the day.

When measuring at home, we recommend checking your size multiple times at different times of the day.

 

〈 Diet 〉

Consuming alcohol or foods high in sodium tends to cause your fingers to swell.

If you are prone to swelling, it may be helpful to consider your finger's state when swollen.

※Please note: If you choose a size based solely on when your fingers are swollen, there is a risk that the ring will slip off when your fingers are at their normal size.

 


◇POINT 3: Ring width and styling◇

 

 

〈 Ring Width 〉

Even with the same numerical size, the fit can feel different depending on the width of the ring.

・Wider rings: Tend to feel tighter.

・Narrower rings: Tend to feel looser.


For example, if a size 10 fits perfectly in a wide ring, you might find that a size 9 or 9.5 fits perfectly in a narrower design.

When using an existing ring as a reference to choose a new one, please keep in mind that the width of the ring can change how it fits. 


〈 Stacking Rings 〉

When stacking rings, they may feel tighter than when wearing a single ring.

For this reason, some people choose a size 0.5 to 1 full size larger when buying a ring intended for stacking.

However, choosing a larger size can lead to the ring slipping off or an engagement ring rotating around your finger.

If you are choosing a ring with the intention of stacking it, we recommend considering the width and the specific combination of rings.
