Ring Size Guide – Find your perfect fit.

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.

Note: If your ideal fit falls between two sizes, we recommend choosing the larger one.

BROSISCUS  rings follow the United States numerical scale but you can use the International Conversion Chart below if you know your ring size in UK standards.   

 On this page you will find the details and downloads you need for three ways to find your perfect ring size.  

  • Measure your ring with a piece of string;
  • Measure the diameter of a ring you own;
  • Measure the circumference of a ring you own against the BROSISCUS ring size chart.

Let’s get started. 

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 – diameter

You can also use the International Conversion Chart by measuring the diameter of your ring 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.
