Japanese ring sizes are based on the ring's inner circumference and differ from both US and UK sizing systems. The conversions above are intended as a general guide. As sizing standards can vary slightly between manufacturers, we recommend measuring an existing ring or consulting a professional jeweller if you are unsure of your size. If you fall between sizes, choosing the larger size is generally recommended.
