Did you find a Blue Billie ring you love but not quite sure what size to order? Don’t worry, we’re here to help- read our ring size guide!

What to keep in mind when you try out your ring size:

Your finger size can change depending on many different factors like temperature and time of day. Hot weather can cause your finger to swell, and when you’re cold your fingers can shrink a bit. Our advice is to try out the size several times throughout the day. The ring is not supposed to come off too easy, it’s should slide smoothly onto your finger and not put too much pressure.

To determine your ring size choose one of the following options:

1. Swing by our store at Regeringsgatan 52 in Stockholm and we will help you find the right size!
2. Measure the size of your finger with a piece of string. Wrap it around your finger and use a ruler to measure the length of the string in millimeter to get your circumference. Convert the length of the string to the right ring size using our Ring Size Chart below.
3. Measure the size of a a ring that fits you. Put the ring on a ruler and measure the internal diameter of the ring in millimeters. Use the conversion chart below to find the right size.
