Size guide for _RINGS

Finding the right ring size doesn’t have to be overcomplicated. With a few quick steps, you can measure at home and find your perfect fit.

Size chart

At CdK, we determine ring sizes based on the inside diameter. If your ring size was measured using a different system, use the chart below to convert it to the corresponding diameter.

Measure your ring size

There are three starting points for measuring a ring size. Choose your starting point for the right sizing guidance.

STARTING POINT 1

“I already own a ring in the right size”

Grab the ring, a piece of paper, a pencil, and a ruler.
Place the ring on the paper and carefully trace the inside of the band with the pencil.
Measure the diameter of the circle you drew with the ruler in millimeters. That’s your ring size.

STARTING POINT 2

“I don’t have a ring in the right size yet”

Take a piece of string, a pen, and a ruler.
Wrap it around your finger where the ring would sit.
Mark where the string overlaps, then measure the string’s length in millimeters. That’s the circumference of your finger.
Use the chart below to find your ring size by matching the circumference to the inside diameter.

STARTING POINT 3

“The ring is a surprise for someone”

In case she already owns a ring in the right size, try to sneak it away and follow the steps in the first column.
Or contact us to help you guesstimate her size. Depending on your situation we can suggest a few other tips. :)
