When buying a smart ring, as with any ring, it is important to choose the right size. When the ring is just the right size, it is comfortable and virtually undetectable to wear.
So how do you measure your ring size if you don't have an old ring or a caliper? Home measuring is easy with a string and a ruler. In addition to the string and the ruler, you will need scissors and a pencil. So here's what you need to do:
1. Cut a short piece of string and wrap it around the finger to be measured at the widest point of your finger. Make sure the string fits snugly and is not too loose or tight.
2. Mark with a pencil where the ends of the string meet. Then spread the string straight out on a flat surface. Then measure the length of the string up to the mark with a ruler. The measurement you get is the circumference of your finger.
3. BKWAT Smart Ring 3 is available in eight different sizes. Size options start at 52 mm circumference and sizes are available up to 70 mm circumference. Choose the size closest to your circumference from the options available. If your size falls between the two sizes or if you are unsure of the correct ring size, we recommend you choose a larger size.
