    FINDING YOUR RING SIZE can easily be determined by measuring your finger or an existing ring.  To determine your ring size, download and print our Ring Sizing Guide.  Ensure the printer is set to print at 100%.

    MEASURE YOUR FINGER with a piece of non-stretchy string about 6” long, or strip of paper about 6” long and 1/4” wide.  Wrap around the base of your finger. Ensure it fits snugly to give an accurate size.  Using a pen, mark the point on the string or paper where it overlaps, forming a complete circle.  Compare the length marked on the string or paper to the lines in our Ring Sizing Guide to determine your ring size. If you’re are between sizes, order the larger size.

    MEASURE A RING that correctly fits the finger you are purchasing the ring for.  Place the ring over the circles in our Ring Sizing Guide and make sure the inside of the ring lines up with the outside of the circle.  If you are between sizes, order the larger size.

    IF YOU’RE BUYING THE RING AS A SURPRISE ask your intended recipient’s parent or friend if they know his/her ring size.  Borrow one of your intended recipient’s rings and use our Ring Sizing Guide.  Make sure to borrow a ring that fits the finger you intend your gift ring to fit.

    OTHER TIPS AND INFORMATION

    • Measure your finger when it’s at its largest size, usually in warm temperatures and at the end of the day.
    • Don’t measure your finger when your hands are cold or damp as this is when your fingers are the smallest.
    • If your knuckle is a great deal larger than the base of your finger measure both the base of your finger and your knuckle. Select a size between the two measurements.
    • Wider rings may fit your finger more tightly than narrower rings of the same size.
    • Your dominant hand (i.e. the hand you write with) is generally slightly larger than your non-dominate hand. Make sure to measure the hand the ring will be worn on.
    • Different countries have different ring-size systems. All sizes listed here are standard US sizes.
    • The average ring size for women is size 7.  The average size for men is size 10.

    Carbon Fiber Junkie rings are listed in standard US sizes.  Use the conversion table to see how finger circumference and other standard international ring sizes convert to US sizes.
