Ring Sizing Guide

At Tripl3, we want to make finding your perfect fit as simple and accurate as possible. Rather than using traditional UK, US, or EU ring sizes, we have measured each ring individually by its inside circumference in millimetres, to provide you with the most accurate measurement. These measurements have then been matched to the closest standard US and UK ring sizes, which can be conveniently found in the ‘sizes’ tab on each product page.

As ring sizing can vary slightly between different countries, brands, and manufacturers, using our own measurements ensures a consistent fit across all Tripl3 jewellery.

How To Find Your Ring Size

Measuring an Existing Ring

  1. Choose a ring that already fits comfortably on the desired finger.
  2. Measure the inside circumference of the ring (the complete distance around the inside edge).
  3. Compare your measurement with our sizes available.

Measuring Your Finger

  1. Wrap a piece of string or paper around the base of your finger.
  2. Mark where the ends meet.
  3. Measure the length in millimetres — this measurement is your finger circumference.
  4. Match your measurement to our Tripl3 ring sizes.

Helpful Tips

  • Measure your finger at the end of the day when your fingers are at their largest.
  • Avoid measuring when your hands are cold, as fingers can be slightly smaller.
  • If you are between sizes, we recommend choosing the larger size for a more comfortable fit.

If you are unsure about your size, we recommend measuring a ring you already own for the most accurate result.
