Women's ring size chart

Women's rings are usually — not always — at the smaller end of the chart, and women's bands are commonly thinner, which changes fit in the opposite direction from wide bands. This page gives the smaller sizes as a quick reference, with the thin-band and stacking guidance that matter most here. It is a filtered view of the same dataset as the full chart, not a different dataset.

Note: There is no separate women's size system: women's rings use the same US, UK, EU and India sizes as all rings. The useful difference is practical — smaller sizes, thinner bands, and rings more often worn stacked — so this page shows US 3–9.5 with that guidance attached.

The chart, US 3–9.5

Women's ring sizes from US 3 to US 9.5 with diameter, circumference, UK and EU
US / Canada	Diameter (mm)	Circumference (mm)	UK (approx.)	EU / ISO
3	14.07	44.2	F	44
3.5	14.48	45.5	G	46
4	14.88	46.7	H	47
4.5	15.29	48.0	I	48
5	15.70	49.3	J	49
5.5	16.10	50.6	K	51
6	16.51	51.9	L	52
6.5	16.92	53.2	M	53
7	17.32	54.4	N	54
7.5	17.73	55.7	O	56
8	18.14	57.0	P	57
8.5	18.54	58.2	Q	58
9	18.95	59.5	R	60
9.5	19.35	60.8	S	61

UK is approximate (published charts disagree by a half-letter in places); EU is the rounded circumference. For an order, give the seller the diameter and circumference columns.

Guidance that matters more at smaller sizes

Thin bands need no width adjustment. Bands under 6 mm wide do not need the wide-band size-up. If a thin-band ring feels tight, the cause is usually the size itself or the knuckle, not the width.
Stacking changes the size. Several thin bands together feel tighter than any one alone (see the stacking guide). If the ring will be worn stacked, fit the stack, not the single ring.
Small fingers, small errors matter more. At smaller sizes, a 1 mm measurement error is a larger share of the circumference than at larger sizes. Measure carefully, twice, in the evening — the same advice as everywhere, with slightly higher stakes.
Do not assume a size from another woman, or from a "standard" women's size. There is no standard women's size to default to. Measure the finger.

Limitations

This page shows US 3–9.5 because that is the range most women's rings fall in, but it is a filtered view, not a limit: women with larger fingers need larger sizes, and anyone needing a size below US 3 needs the seller's chart, since the site's dataset starts there. No claim is made about what size any individual woman wears — measure the finger, do not assume it from gender.
