A ring should fit snugly, yet comfortably. It should go on fairly easily, but come off with slight effort. You can determine your ring size fairly accurately by following the steps below and referring to the chart. 1/4 sizes are also available for the most precise fit. It should be noted that wider rings will fit more snugly than thinner bands. People with large knuckles sometimes have a problem with fit because rings that are big enough to go over the knuckle fit too loosely once they are beyond the knuckle. There are a number of remedies for these special cases. Please contact customer service for advise.
