If you don't know your ring size, follow these instructions and you should be able to determine it.

There are several foolproof methods to determine your correct ring size.  The most widely used are the following:

1)  Measuring your finger with our Sizer Strip:

Ring Sizer in PDF format

You can use our ring sizer above. In order to print it to scale, be sure that your printer is set to 100%.  In other words, make sure that you have not reduced the print size in 'page set up.' You can verify that the sizer printed correctly by measuring it with a ruler; it should measure from left to right: 3 3/8 inches.  If unsure about your printer settings, click here to print an already formatted Ring Sizer, in PDF format (a PDF file and requires Adobe Acrobat Reader. If you do not have Acrobat Reader download it for free.)

Once you have printed the sizer,  you may cut it out and use it or try the following directions to find your ring size:

1. Wrap a piece of loose string around your finger. Be sure to allow for the size of your knuckle.
2. With a pen, mark the point on the string where the end meets.
3. Using the chart, place the end of the string on the left hand line  next to the letter "A" and stretch the string along the sizer toward the numbers.
4. The pen mark on your string should line up with a number to indicate your ring size.

2)  Using a String to measure your finger:

If you don't like to use our ring sizer, you can just cut a thin stripe of paper, wrap it around your finger, mark the paper where it meets and then measure it with a ruler. Then you can compare it to our chart of ring sizes below (NOTE THESE ARE AMERICAN RING SIZES):

Ring Size	Paper Length in Inches
4	1 13/16
5	1 15/16
6	2 1/16
7	2 1/8
8	2 1/4
9	2 5/16
10	2 7/16
11	2 9/16
12	2 5/8
13	2 3/4
14	2 7/8

3)  Using an existing ring to determine your size:

Measure the diameter (distance across) in millimeters of a ring you currently wear. Find the nearest measurement on the chart below. That's approximately your ring size. (When in doubt between two sizes, it is always safer to go to the next larger ring size. This ensures your new ring will fit you.)
 

An example of measuring the diameter of a ring. The inside of this ring is approximately 18mm in diameter, making it a size 7 on the chart below.

 

Ring Size	Circumference (in mm)	Inside Diameter (in mm)
4	48	15 mm
5	51	15.3 mm
6	54	16.2 mm
7	56	17.1 mm
8	59	18 mm
9	62	18.9 mm
10	65	19.8 mm
11	68	20.4 mm
12	71	21.3 mm
13	74	22 mm
14	77	23 mm
15	80	23.9 mm

 

       

5)  International Ring Sizes:

Ring sizes vary from country to country.  We use the American - Canadian standard:  all you need to do is find the equivalent American size to place your order!
