Men's ring size chart

Men's rings are usually — not always — at the larger end of the chart, and men's bands are commonly wider, which changes fit. This page gives the larger sizes as a quick reference, with the width and knuckle 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 men's size system: men's rings use the same US, UK, EU and India sizes as all rings. The useful difference is practical — larger sizes, wider bands, and knuckles that more often decide the fit — so this page shows US 7–13.5 with that guidance attached.

The chart, US 7–13.5

Men's ring sizes from US 7 to US 13.5 with diameter, circumference, UK and EU
US / Canada	Diameter (mm)	Circumference (mm)	UK (approx.)	EU / ISO
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
10	19.76	62.1	T	62
10.5	20.17	63.4	U	63
11	20.57	64.6	V	65
11.5	20.98	65.9	W	66
12	21.39	67.2	X	67
12.5	21.79	68.5	Y	69
13	22.20	69.7	Z	70
13.5	22.61	71.0	Z+1	71

UK and EU columns carry the same caveats as the full chart: UK is approximate (published charts disagree by a half-letter in places) and EU is the rounded circumference. For an order, give the seller the diameter and circumference columns.

Guidance that matters more at larger sizes

Wider bands are common. Men's bands are frequently 6–10 mm wide. Apply the wide-band guidance: consider half a size up for 6–8 mm, a full size up for 8 mm and wider, from a thin-band measurement.
Knuckles decide more often. Larger hands often have more prominent knuckles relative to the base. Measure both points and size for the larger, as the knuckle guide explains.
Do not assume a size from another man, or from a "standard" men's size. There is no standard men's size to default to. A finger measurement takes two minutes and is the only evidence that counts for that finger.

Limitations

This page shows US 7–13.5 because that is the range most men's rings fall in, but it is a filtered view, not a limit: men with smaller fingers need smaller sizes, and anyone needing a size above US 13.5 needs the seller's chart, since the site's dataset ends there. No claim is made about what size any individual man wears — measure the finger, do not assume it from gender.
