eu ringsize · 48 – 66

Find your size.

Two minutes, a strip of paper and a ruler. EU ring sizes are simply the inside circumference in millimetres.

01
Wrap

Wrap a strip of paper around the base of your finger. Snug, not tight — it should still slide over the knuckle.
02
Mark

Mark exactly where the paper overlaps, then lay it flat on the table.
03
Measure

Measure from the end to the mark in millimetres. That number is your EU size — 54 mm is size 54.

measure in the evening Fingers are largest at the end of the day and in the warmth — cold hands measure small.
wide bands, size up Distorted I and II are 12–15 mm wide and sit tighter than a thin band. Between two sizes, take the larger.
measure three times Use the average. Paper stretches less than string, so it is more reliable.
own a ring that fits? Measure its inside diameter in millimetres and use the diameter column.
