Find Your Ring Size

How do you order a ring without trying it on? If it's too small, it won't fit over your knuckle, and if it's too big it won't stay on your finger! Avoid such travesties with our ring size guide.

String and Ruler Method

Supplies Needed

Ruler with millimeter measurements

Non-stretchy string or a strip of paper


    Wrap a piece of non-stretchy string or a strip of paper around the base of your finger.

    Mark the point where it overlaps using a pen or fine-point marker.

    Measure the length in millimeters using a ruler.

    Compare the length to the ring size chart to determine your ring size.

      Measuring Tips

      All measurements match the inside circumference of the ring.

      If your finger measurement falls between sizes, order the larger size.

      Fingers are smaller in the morning and bigger by the end of the day. Measure your fingers at the end of the day.

      Take multiple measurements to ensure an accurate reading.

      Weather and temperature affect finger size. Do these measurements where it's moderately warm.

      If you have large knuckles, measure both the base of your finger and your knuckle, and select a size between the two.

      Fingers tend to be one half-size larger on your dominant hand.
