Ring Sizer
When you buy a ring from Paris Jewellers, we size it for you so can enjoy your purchase/gift as soon as you receive it.
METHOD 1
Get a string, thread, or ribbon and wrap it around the finger you intend to wear the ring on. Make sure it is snug around your finger so that it’s comfortable and not too tight. Measure the diameter of the string and compare it to the sizing chart on the right.
METHOD 2
Take a ring that fits comfortably on the finger you are buying the ring for, and put it on top of the circles in the chart on the right. Make sure the inside of the ring lines up with the outside edge of the circle. This method is great if you are buying a ring for someone else and you need to find out their ring size in secret.
METHOD 3
Cut out the ring sizer below and cut a slit where it says Your Size. Slide the end of the sizer into the slit and wrap the sizer snugly around your finger. Make sure that it’s comfortable and not too tight. Read the number at the slit where it says Your Size. This is your ring size.
