Ring Size Guide

Real babe’s know their ring size. Don’t worry we’ve got you!

Measure your finger

1. Wrap a strip of paper or a piece of string around your finger, exactly as you would like your ring to sit and feel.

2. Make sure that the paper or string is snug yet comfortable.

3. Using a pen, mark the paper or string at their point of connection.

4. Using a ruler, measure the length of your paper or string to the marking (in mm).

5. From this measurement, you will be able to use our chart below to find your AU ring size we use at By Baby!
