Size guide

Two ways to measure

With a ring that fits
Measure the inside diameter, edge to edge, and find it in the “Diameter” column.
With a strip of paper
Wrap it around the base of your finger, mark where it meets and measure the length: that is the circumference, which is the EU size.

Your EU ring size is the inside circumference of the ring in millimetres: a size 52 measures 52 mm around the inside. The easiest way to find yours is to measure a ring that already fits the same finger: take its inside diameter and find it in the table below. Or wrap a thin strip of paper around the base of the finger, mark where it meets and measure the length flat. Fingers swell in the heat and towards evening, so measure more than once; if you fall between two sizes, choose the larger, and go up one size for rings wider than 6 mm. The UK and US sizes are the nearest equivalents on a standard conversion chart, so treat them as a guide rather than an exact match. Open rings adjust gently to the range given on their page: close or open them a little at a time, and never bend them back and forth. Not sure? Send us a message, or come to the shop in Metsovo and we will measure your finger.
