EU ring size chart

EU sizes with US and UK matches

Each row gives the European size with its US and UK names, and two measurements of the inside of the ring: the distance all the way round (the circumference), and the width straight across (the diameter). The numbers come from the standard ring size table.

If your measurement falls between two rows, pick the nearer one. European sizes go up one millimetre at a time, so there are no half sizes.

Where the European numbers come from

Across most of Europe, the size is simply the number of millimetres round the inside of the ring, as the international ring size standard sets out. That is why European numbers look so much bigger than US ones: they are real millimetres, not a count that starts at 1.

So a size 54 ring measures 54 mm round the inside, and in the United States the same ring is a size 7.

Does an EU size mean the same thing across Europe?

Mostly, yes, though two other kinds of number turn up in some shops. Italy, Spain and Switzerland use smaller numbers for the same ring: their size 10 is a European 50, and a US 7 is a size 14 there. Shops in Germany and the Netherlands sometimes give the width across the inside instead, so a German "17" can be the same ring that most of Europe calls 54.

If a number looks odd, ask the shop which measurement it means. The chart gives both for every size.

Measuring in centimetres and millimetres

Many rulers show centimetres. A paper strip of 5.4 cm round your finger is 54 mm, so your European size is 54: the number you measure is the size itself.

To find the US or UK name, look along that row of the chart: a 54 is a US 7 and a UK N½.
