Ring Size Guide

Getting your ring size right matters โ€” a ring that is too tight is uncomfortable, and one that is too loose can slip off. Here is how to measure at home accurately.

How to Measure Your Ring Size

  1. Use a strip of paper or thin string. Cut a strip no wider than 1 cm. Wrap it around the base of the finger you want to wear the ring on.
  2. Mark where it meets. Use a pen to mark the point where the strip overlaps to form a complete circle.
  3. Measure the length. Lay the strip flat and measure from the end to your mark in millimeters. This is the circumference of your finger.
  4. Find your size in the chart below.

Before you measure:

  • Measure at room temperature โ€” fingers shrink when cold and swell when warm
  • Measure at the end of the day when fingers are at their largest
  • If your knuckle is larger than the base of your finger, measure the knuckle too and size up

Tips

  • Between sizes? Go up half a size โ€” a slightly loose ring is more comfortable than one that is too tight, and easier to remove.
  • Dominant hand fingers are often slightly larger than the other hand. Measure the specific finger you plan to wear the ring on.
  • Knuckle check: if the ring slides over your knuckle easily but feels loose at the base, try a half size down.
  • Not sure? Order two adjacent sizes and return the one that does not fit โ€” see our Returns & Exchanges policy.
