You'll need a Ruler and a thin strip of paper

Cut a thin strip of paper
Wrap the paper around your finger. Make sure the paper is below the joint of your finger and close to your knuckle.
Mark the spot where the paper meets and measure the distance with your ruler.
Use the following chart to determine your ring size. Rings also come in half sizes, the measurements of which, of course, will fall somewhere in between the whole sizes.

Despite how it sounds, gold-filled metal is not actually filled with gold. “Gold-filled” is simply an age-old term that became accepted in the jewelry industry.
Today, gold-filled is a quality designation that’s regulated by the Federal Trade Commission.
To merit a “GF” stamp, the material must have a gold layer that’s at least 10-karat mechanically applied to a base metal; the karat gold layer must also be at least 1/20 (5%) of the item's total weight.
Gold-filled is made by heat- and pressure-bonding a thin layer of karat gold to a brass (or other base metal) core. The value of gold-filled is greater than gold-plated because gold-filled has an actual layer of karat gold, not just a microscopic film, as is the case with gold-plated items.
