Ring Size Guide

 

Find Your Ring Size:

Follow the directions below to measure your ring size:

Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inches).

Wrap it around the base of the appropriate finger.

Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.

With a ruler, measure the length from the starting end of the string/paper to the pen mark

Use this measurement and the chart to the right to determine your ring size

For the most accurate reading, measure the finger at the end of the day when the finger is the largest.

Tips for Measureing Ring Size:

Here are some tips to make your ring size measurement more accurate:

After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.

Don't measure cold fingers. This is when fingers are their smallest.

For the most accurate reading, measure the finger at the end of the day when the finger is the largest.
