Ring Size Guide

Before you get started make sure you are measuring the finger, or an existing ring, that sits on the finger you would like your new ring to sit on. Your ring should sit comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle.

There are a few different ways that you can measure your ring size.


Measure the inside diameter of your existing ring, or the ring of the person you are buying for.
What you’ll need: A Ruler and the ring you would like to measure.

MEASURE the inside diameter of the ring and round up until the nearest mm.
The diameter of your ring is the measurement of a straight line from one side to the other.

COMPARE the length you just measured to the ring size chart below or use our custom Ring Size Calculator below.


Calculate your exact ring size in 5 easy steps! 
What you’ll need: a strip of paper, a ruler, and a pen or pencil.

CUT a strip of paper about 8 inches long and about 0.5 inch wide.

WRAP the paper strip around the widest part of the finger you would like your customized ring to sit on. The widest part of your finger may be at the joint. Don’t worry; your ring won’t actually sit here.

USING a pen or pencil, mark the point on the paper where the strip forms a complete circle and begins to overlap.

TAKE your ruler and measure from the edge of your paper up to the line you just marked. Measure up to the nearest millimeter, rounding up if necessary.

USING the length you just calculated, consult our handy chart to find your ring size.


If all you have at home is a ring to compare to, you can easily print out our PDF Ring Size Finder and find your exact match using our diagrams! NOTE: Make sure that the ‘fit to page’ box is unchecked.
Simply place your ring on the size diagrams until you find the perfect match, then find your size on our size chart. Make sure you double check the proportions using the print accuracy guide at the top of the page.
