Ring Size Guide – Find Your Perfect Fit.

The right size ring for you

Your ring should feel comfortable for everyday wear.  We recommend selecting a ring size that can be easily put on and taken off your finger.


If your ideal fit falls between two sizes, we recommend choosing the larger one.
BROSISCUS rings generally follow the United States numerical scale but you can use the International Conversion Chart below if you know your ring size in UK standards.


If one of our rings fall  outside of the charts, the exact inner diameter will be marked on the individual product page so be sure to check. 

Your finger size will expand and change throughout the day depending on the elements such as weather. It is a good idea to measure in the morning and again in the afternoon to determine the best size. The fit should be comfortable but not be able to slide off the finger too easily. Check your length against this chart.

Measure a ring you own

You can also use an International Conversion Chart by measuring the diameter of a ring you already own using a ruler. Once you have the inner diameter of the ring in millimetres, match the closest number on the International Conversion Chart above to find your ring size.
