Ring Size Guide

Measure Circumference (String Method)

Wrap a piece of string, floss, or a thin strip of paper around the base of your finger and mark where the ends meet. Lay the string flat and use a ruler or measuring tape to measure up to the mark, then use the sizing chart to select your ring size.

Measure Internal Diameter (Existing Ring Method)

Take a ring that already fits the finger you’re purchasing for and lay it flat. Using a ruler or digital caliper, measure the inside diameter straight across (edge-to-edge), then use the sizing chart to find your matching US size.

Tip: Make sure you’re measuring the inner opening — not the metal edges.

Size (US)	Internal Diameter (mm)	Circumference (mm)
5	15.7 mm	49.3 mm
6	16.5 mm	51.9 mm
7	17.3 mm	54.4 mm
8	18.1 mm	57.0 mm
9	19.0 mm	59.5 mm
10	19.8 mm	62.1 mm
11	20.6 mm	64.6 mm
