Ring Size
Ascertaining your correct ring size is simple and can be done in different ways. Always make sure you hands are warm when you measure your fingers and go for a comfortable fit.
If measuring a ring you already wear try to choose one with a similar band width to the ring you are going to order. The thicker the width of the band (shank) the larger the size you require.
Method 1: Measure in millimetres the inside diameter across a ring that is comfortable on the finger you want to wear your new ring on.
Method 2: Wrap a piece of string or paper loosely around the base of the appropriate finger, going for the snuggest fit that slips over your knuckle. With a pen mark the point where the circle of string/paper overlaps. Measure this length in millimetres.
Use the measurements obtained to check your size in the chart below and order by the UK Ring Size.
