A ring that fits right stays with you for the long haul. Use this guide to get your size right the first time.

 

How to Measure at Home

  • Option A:  Measure Your Finger Wrap a strip of paper or non-stretchy string around the base of your finger. Mark the overlap and measure the length in mm. This is your Circumference.
  • Option B:  Measure an Existing Ring Take a ring that already fits and measure the inside diameter (straight across the center, excluding the metal) in mm.

Use the chart below to determine the ring size

Essential Tips：

  1. Wide Bands: For bold or heavy rings, size up by 0.5 or 1 full size. They grip more skin and feel tighter.
  2. The Knuckle Rule: The ring should slide over the knuckle with slight resistance but sit comfortably at the base.
  3. When to Measure: Measure in the evening when your fingers are at their largest. Avoid measuring when your hands are cold.
  4. Dominant Hand: Your "working hand" is usually about half a size larger. Measure the exact finger you plan to wear the ring on.
