Ring Size Guide

Finding your ring size at home is simple. Use our printable sizer, or measure a ring you already own. Canadian and US ring sizes are the same.

Option 1 — Printable Ring Sizer (most accurate)

Download our printable ring sizer (PDF). Print it at 100% scale ("Actual size" — not "Fit to page"), check the credit-card outline matches, then either place a ring on the true-size circles or cut out the paper strip sizer.

Option 2 — Measure a ring you own

Measure the inside diameter of a ring that fits the finger in millimetres, then find your size in the chart below.

International Ring Size Chart

Shopping from outside Canada or the US? Find your size in the system you know. European (EU) sizes are based on the inside circumference in millimetres; the UK and Australia share the same letter-based system, while Japan and China use their own numbered system. Conversions are approximate — when in doubt, go by the millimetre measurements.

Tips for the Best Fit

• Measure at the end of the day, when your fingers are at their largest.
• Make sure the sizer slides over your knuckle with slight resistance.
• Wide bands fit tighter — if you are between sizes, size up.
• Cold fingers measure smaller; warm fingers measure larger. Measure at room temperature.
