Ring Size Guide
A European ring size is the inside circumference of the ring in millimetres. A size 56 ring measures 56 mm around the inside.
Measure at home
With a ring you already wear. Measure straight across the inside of the ring, edge to edge, in millimetres, and find that inner diameter in the table below.
With a strip of paper. Wrap it snugly around the base of the finger, mark where the end overlaps, then lay it flat and measure the length in millimetres. That length is your European size.
Measure at the end of the day, when fingers are largest, and check that the ring will still pass over the knuckle.

Between two sizes
Wide and heavy rings sit closer than a slim band. For the Heavy Signet, or whenever you fall between two sizes, choose the larger size.
