Frequently asked questions
How do I convert a Germany ring size to US?
Enter your Germany size in the converter above, or find it in the chart below and read across to the US column. Both use the same canonical chart on Ringsizely.
Are Germany and US ring sizes the same?
No — they use different scales, so the numbers do not match and must be converted. International equivalents are approximate; when possible, order by millimetre diameter.
How should I confirm a converted ring size before ordering?
Measure the same finger or a ring that fits with a second method. For an expensive, wide, or non-resizable ring, check the retailer's chart and confirm with a physical sizer or jeweller.
