It takes five easy, quick steps to calculate your exact ring size. To measure, you’ll just need a strip of paper, a ruler, and a pen or pencil.
CUT a strip of paper about 13 centimeters long and about 1 centimeter wide.
WRAP the paper strip around the widest part of the finger you would like your customised ring to sit on.
The widest part of your finger may be at the joint. Don’t worry; your ring won’t actually sit here.
USING a pen or pencil, mark the point on the paper where the strip forms a complete circle and begins to overlap
TAKE your ruler and measure from the edge of your paper up to the line you just marked. Measure up to the nearest millimeter, rounding up if necessary.
USING the length you just calculated, consult our handy chart to find your ring size.
