Ring Size Guide

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.

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.
