Ring Size Guide

There are a few popular methods to determine your ring size. Some are more accurate than others but for the best results, we would always recommend visiting a jeweller to be properly measured.

The best time of day to measure your ring size is in the evening. Our fingers naturally change size throughout the day and it’s best to measure them at when they are at their largest to ensure you get a comfortable ring fit. During the course of the day, it is normal for your fingers to swell and they will be at their largest by the evening. Avoid measuring your fingers when they are cold, as at this point they can be at least half a size too small. We recommend sizing your fingers a few times to make sure your ring size measurement is as accurate as possible. In case your measurement falls between two sizes, pick the larger size.
