You can measure your ring size in a number of ways. At Bonito Jewelry, our rings are measured numerically, and follow the US chart.

If you already know your ring size in a UK or European size, then please see the conversion chart below to see what this would equate to in a US size.

 

To know your ring size, start by measuring your finger.

    1. Wrap a thin strip of paper or piece of string comfortably around the identified finger.
    2. Mark the end and measure the distance. This is the circumference.
    3. Match the measurement to the circumference column in the conversion chart below.

If you would like to have your own measuring tool, we recommend this affordable measuring tape from Amazon: shop here. 

 

Are you buying a ring as a gift? 

The best and easiest way to find out someone else’s ring size is to borrow one of their rings, making sure it is from the correct finger and measure the inside diameter. 

(*) For increased accuracy, use a ring in a similar style and with a similar band width to the ring you intend to buy.
