Size Guide - Rings

Find your ring size

Getting your ring size right is one of the most important steps when ordering. Because most Luxumoon rings are made to order, we want to make sure you order with full confidence.

How to measure your ring size

There are a few easy methods you can use at home:

Method 1 — 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 want to measure
  3. Mark where the strip or string meets itself
  4. Measure the length in millimetres with a ruler
  5. Use the chart below to find your size

Method 2 — Existing ring

  1. Take a ring that already fits the correct finger
  2. Measure the inner diameter in millimetres
  3. Match it to the chart below

Tips for accurate sizing

  • Measure at the end of the day — fingers are slightly larger in the evening
  • Fingers swell in warm weather and shrink in cold — measure at room temperature
  • If you are between two sizes, order the larger size
  • For wide bands (4mm and above), consider going half a size up for comfort
  • For eternity bands, please contact us before ordering as these cannot be resized
