Ring Size Guide
Step 1. Pick a ring you already own that fits the finger you have in mind.
Step 2. Measure the inside diameter in millimetres, edge to edge.
Step 3. Find that diameter in the table below. If you land between two sizes, take the larger one.
Measure at the end of the day, when fingers are at their largest. Cold hands measure small.
