Ring size guide

Not sure of your ring size?

1. Measure a ring that already fits

Measure the inside diameter at the widest point in millimetres. An inside diameter of 17.0 mm corresponds to ring size 17.0.

2. Measure your finger

Use a narrow strip of paper, keep it snug but not tight, and measure the circumference in millimetres. Measure 2–3 times, preferably later in the day.

Size	Inside Ø	Finger circumference
15,0	15,0 mm	47,1 mm
15,5	15,5 mm	48,7 mm
16,0	16,0 mm	50,3 mm
16,5	16,5 mm	51,8 mm
17,0	17,0 mm	53,4 mm
17,5	17,5 mm	55,0 mm
18,0	18,0 mm	56,5 mm
18,5	18,5 mm	58,1 mm
19,0	19,0 mm	59,7 mm
19,5	19,5 mm	61,3 mm
20,0	20,0 mm	62,8 mm
20,5	20,5 mm	64,4 mm
21,0	21,0 mm	66,0 mm
21,5	21,5 mm	67,5 mm
22,0	22,0 mm	69,1 mm
22,5	22,5 mm	70,7 mm
23,0	23,0 mm	72,3 mm
23,5	23,5 mm	73,8 mm
24,0	24,0 mm	75,4 mm

Between two sizes? Ring width and your knuckle also affect fit. Ask us before ordering if you are unsure.

What if the size is not quite right?

For a ring purchased from us, you get the first ring size adjustment at a reduced price compared with our standard price, if the ring can be resized.

Finger size naturally varies.

Your finger can be a different size in the morning and evening, as well as in warm and cold weather. A ring does not need to feel exactly the same every day. A size adjustment is worth considering only if the ring is repeatedly too tight or too loose at different times.
