Ring sizer to measure your fingers US/ Canada and UK sizing Full and Half Sizes Directions: Try on sizers until you find one that fits. Make sure it is not too tight and can move over your knuckle without too much difficulty. Ring should be snug but not tight and never loose. It is especialy important to have your ring fit snug if you are ordering a ring with a larger centre stone ( 2 carats and above) to avoid your ring tipping on your finger. If you find that a full size is too big and a half size is too snug it means you are a quarter size. For example, if you try on a size US 5 and its too loose but the US 4.5 is too tight then you would be a US 4.75. We recomend going up one quarter size when purchasing eternity bands since these rings cannot be resized.
