How to measure ring size

We custom-make each ring to your size.

To accurately measure your ring size, we recommend using a specialized tool called a ring sizer.
We recommend using a ring sizer for measurement.

Measuring Tips

・Each ring's product page includes features of the ring and tips for choosing the right size. Please refer to them as well.

・If a ring sizer gets stuck on your finger, use dish soap or hand soap to remove it.

・Fingers may swell due to temperature and time of day, causing size fluctuations. We recommend measuring multiple times at different times.

*Fit varies from person to person. The measuring method introduced is only a guideline, so please choose the size according to your preferred fit.
However, please note that if your fingers become congested when you clench your hand, the ring is too tight.

How to use a ring sizer

We use a Meiko brand comfort fit ring sizer.

For this explanation, the ring sizer has been removed from the wire.
Please use the rental item without removing it from the wire.

In this case, measure by resting the excess dangling sizer on a table, or by supporting the weight of the sizer with your other hand that is not being measured. If too much weight is applied to your finger, you will not be able to measure correctly.

Put on each ring sizer one by one to find the size with your preferred fit.

The number inscribed on the ring sizer is the ring size.
In this case, the preferred size was 15.

For narrow rings, a slightly tighter fit is more comfortable. While it varies by individual, if you're unsure, we recommend going with a slightly smaller size.

If your knuckles are thicker than the base of your finger, measure at the base of your finger. If the ring gets caught on your knuckle and won't go on or off, gently bend your finger when putting on or taking off the ring. Please refer to the video below for more details.

For wider rings, measure using two consecutive ring sizers.
