Ring size chart (English)

The table below provides a comparison of Japanese ring sizes with those of your country.
Please check it out with your usual size to help you make your purchase.

Muska's rings follow Japanese size standard but we will adjust a purchased ring size so that it is as close to your usual size as possible.
Generally speaking, our ring sizes range from JP size 7 to 20.
However, some products may have a smaller range, depending on their design.
Also, as each item is made by hand, there may be a little error in dimensions.
