How To Measure Your Ring Size

To help you find your ring size, please view our ring size chart, request a free ring sizer, and tips for measuring at home. 
Before you begin taking your measurements, pick the finger on which you want to wear your ring. The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so keep that in mind when measuring for your ring size. These standard ring sizes can help guide you in the right direction. If you do not see the size you need, contact our experts for help placing a special order. There are also a number of at-home methods to find your ring size.

Find Your Ring Size With Our Ring Sizing Guide

This is a chart that will be extremely helpful for you to determine the ring size that you need. You can either make use of a tape or a small piece of string to measure the area that will be occupied by the ring. When it becomes a complete circle, make a mark on such string. All MSBLUE rings are specified in standard US sizes. View the conversion chart to see how US sizes map to finger circumference, as well as how US sizes convert to Canada, Australia, UK and other countries.

Ring Size Tips:
1) Our dominant hands are generally slightly larger — make sure you measure the right finger on the correct hand!
2) Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
3) If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.
