Ring Size Guide

All of our rings are comfort fit and come in sizes 2.5 to 19, including half sizes. Tungsten can't be resized, so take a minute to get your size right. Here are three easy ways to find it.

1. Use a ring that already fits

Measure the inside of a ring that fits the finger you're sizing, straight across, in millimeters. Then find that number in the "Inside Diameter (mm)" column of our Ring Size Conversion Chart.

2. Measure with a string or a strip of paper

Wrap a piece of string or a thin strip of paper snugly around the base of the finger.
Mark where the end overlaps. Make sure it would still slide over your knuckle.
Lay it flat and measure up to the mark in millimeters.
Find that number in the "Inside Circumference (mm)" column of the Ring Size Conversion Chart.

3. Get our plastic ring sizer for $5.99

Sizing tips

If you land between two sizes, order the half size. For example, between 5 and 6, order a 5.5.
If you measure a quarter size, such as 10¼, order the size just below it: a 10.
Measure at the end of the day, when your fingers are at their largest, and not when your hands are cold.
Your shoe size is often close to your ring size, which makes a handy double-check.

Not sure which width?

A U.S. nickel is about 2mm thick, so you can stack nickels to picture a width: 2 nickels is about 4mm, 3 nickels about 6mm, 4 nickels about 8mm and 5 nickels about 10mm. See our width guide.
