Ring Size Guide

Getting the right ring size is especially important for tungsten rings — unlike gold or silver, tungsten cannot be resized after manufacturing. Take a moment to measure carefully before placing your order.

How to Measure Your Ring Size at Home

Method 1: Use a String or Paper Strip

  1. Cut a thin strip of paper or use a piece of string
  2. Wrap it snugly around the base of the finger you plan to wear the ring on
  3. Mark where the paper or string overlaps
  4. Measure the length in millimeters
  5. Use the chart below to find your size

Method 2: Measure an Existing Ring

  1. Place a ring that fits well on a ruler
  2. Measure the inner diameter in millimeters
  3. Match the measurement to the chart below

Sizing Tips

  • Measure at the end of the day — fingers are slightly larger in the evening due to natural swelling
  • Measure when warm — cold temperatures can cause fingers to shrink temporarily
  • Consider the width — wider bands (8mm+) tend to fit more snugly; if you're between sizes, size up for wider rings
  • Dominant hand — your dominant hand is typically slightly larger; measure the specific finger you plan to wear the ring on
  • When in doubt, size up — it's easier to add a ring adjuster than to exchange a tungsten ring
