Rings Size Guide

Sizing can be tricky. If your knuckle's larger than the base of your finger, split the difference between two sizes. You need a fit that slides on smoothly but stays put. So, take two measurements and meet somewhere in the middle.

US Ring Size	Inner Diameter (mm)
2	13.3
2.5	13.7
3	14.1
3.5	14.5
4	14.9
4.5	15.3
5	15.7
5.5	16.1
6	16.5
6.5	16.9
7	17.3
7.5	17.7
8	18.1
8.5	18.5
9	19
9.5	19.4
10	19.8

Measuring Tips for a Flawless Fit

When measuring, make sure you are at a normal body temperature; fingers shrink in the cold & expand in the heat!
Stay cool, don't measure when you're hot! Fingers shrink in the cold and expand in the heat.
Skip the salted rims before sizing - cocktails and swelling fingers don't mix, so you will not get an accurate measurement.
When in doubt, size up. If you're caught between sizes, don't sweat it. Go for the larger size and enjoy a fit that's just right.
