HOW TO MEASURE AND CONVERT YOUR RING SIZE

When it comes to determining the size of your ring, it can be a daunting task. We highly recommend that you get your ring size measured by reputable jewelers until at least two agree on the same ring size. However, if you’re lazy like us and would like to do it in the comfort of your own home, then look no further. See our ring size conversion chart below to determine your ring size within your region.
