Measure size

Knowing your ring size isn't always straightforward — especially since sizing systems vary between countries.

In Sweden, ring sizes are measured in millimetres (the inner diameter of the ring). Here's how to find yours:

Place a ring that fits well on a ruler and measure the inner diameter from edge to edge. The measurement in millimetres is your ring size. For example, if the inner diameter is 17 mm, your ring size is 17.

Use the conversion table below to find your equivalent US or UK size:

mm	US size	UK size
14	3	F
15	4	H
16	5	J
17	6	L
17.5	6.5	M
18	7	N
18.5	7.5	O
19	8	P
19.5	8.5	Q
20	9	R
21	10	T

If you're unsure, we recommend sizing up rather than down.
