How to measure your finger and determine your ring size.

There are a few easy ways to determine your ring size in the comfort of your home. Here are three easy options you can use to find a ring size that will fit you best:

Option 1: Measure your finger

Instructions:

Get a non-stretchy string or paper about 6" long.
Wrap around the base of your finger. It has to fit snug, but not too tight.
Mark the point on the string/paper where it overlaps forming a circle.
Measure the string/paper up to that point in Millimeters.

Option 2: Measure a ring you already own.

If you have a ring that already fits you well, you can use a ruler to measure the interior diameter of a ring.

Take a ruler and measure straight across the interior of the ring from edge to edge as shown the image from above.
Take the diameter measurement in millimeters, and then use our measurement-conversion chart below to find your ring size.

Option 3: Do it yourself ring sizer.

Download and print the following ring sizer here.
Please make sure your print scale is setting is set to 100 percent and the “fit to page” box is left unchecked from within your printer's settings in order to get an accurate measurement from the printout.
Cut-out the pre-measured strip of paper and use it to measure your finger and determine your finger ring size.

All listed measurements are accurate according to United States standard ring sizes. However, some of our rings have the Comfort Fit feature, this means the inner edges are rounded to allow for easier removal and maneuverability. These rings can sometimes feel up to half a size larger due to this feature. Please Take this into consideration when placing your order.

In order to ensure you are ordering the correct size, we recommend either purchase a ring sizer or visiting a local jeweler before placing your order. Please do not purchase multiple rings solely for sizing purposes, such orders may be subject to cancellation as per our policy.
