Ring size guide
Typically rings should be made to a standard size, however you will find that many ring size guides differ.
Our rings are made to the standard USA sizes, we then provide a guide as to the nearest UK size (There is not always an exact match).
We recommend using a ring sizer mandrel with both UK & USA sizes.
Below you will find a ring size guide which also shows the inside diameter of of our rings which should be used for a more accurate measurement.
