Cut a piece of paper or thin piece of string approximately 10cm long.
Wrap the string around the finger you wish the ring to fit on just above the knuckle.
Pull it fairly tight but not so that it is uncomfortable.
Mark where the string or paper starts to overlap.
Use our guide below to achieve your desired ring size
If your size sits in between two sizes, for example circumference 53.5mm, we recommend going up a size, so in this case our size would be 7.
If the ring size is only slightly above a particular size, i.e. 52.7mm, we would recommend sticking with a size 6.
Our ring sizes are based on US sizes, we have created a recommended guide based on the ring sizes we offer.
PLEASE NOTE ALL OUR RINGS ARE BASED ON STANDARD US SIZES
