A - IF YOU KNOW YOUR SIZE:

If you know your size or finger measurement (in mm), you can go to any online ring conversion website and enter your info.
Here is an example of a ring size conversion chart: http://www.onlineconversion.com/ring_size.htm

B - MEASURING YOUR FINGER WITH A PRINTED SIZE CHART:
  1. Right-Click on the image below and select Save Image As.
  2. Print the image without scaling and ensure the length from the 'Read Size Here' line to the end is 3.5 inches.
  3. Cut out the printed image, then wrap the sizer around the desired finger. Read the number next the 'Read Size Here' line. 

C - MEASURING YOUR FINGER WITH PIECE OF PAPER:
WHAT TO DO:
  1. Cut a strip of thin paper at least 3 inches long and less than 5 mm wide
  2. Wrap it snugly around your ring finger at the base of the knuckle
  3. Using a pen or pencil, mark where the ends overlap
  4. Lay it flat and use a ruler to measure the length in millimeters
  5. Use the CHART to find your ring size and voila, you're all set.

*Note: The above method is very simple because we have access to our own fingers. Unfortunately, this method is not 100% accurate. To minimize errors, wrap a paper around your finger 3 times. Next, measure the length of the piece and divide this number by 3. Thus, your measurements will be more exact.

D - MEASURING YOUR FINGER WITH A STRING / FLOSS:
  1. Wrap the string/floss snug around your finger, make sure it's nice and tight and cut it carefully;
  2. Measure the distance with a ruler (in mm); that's your finger's circumference;
  3. Use the CHART to find your ring size and voila, you're all set.

        E- WITH A RING SIZE MEASURING DEVICE.
        1. Wrap the measuring ring around your finger one by one, until you are sure that it's nice and tight ("-size" means half yard here);
        2. Find your size straightly and order the ring you want.
        F- HOW TO REDUCE THE SIZE OF A RING:
        If you would like to size your ring down, you can purchase the ring size adjuster.
