Ring Size Guide

Found the perfect ring, but not sure of your ring size? No worries—we’ve got you covered with a quick, at-home guide!

You’ll need:

  1. A piece of string, tape, or even dental floss.
  2. A pen or marker.
  3. A ruler (preferably in centimeters).

Step 1: Measure
Take the string (or tape) and wrap it around the finger where you want your ring to sit. Make one full wrap around without pulling it too tight—it should feel just right or even a little loose.

Step 2: Mark
Once it feels right, use the pen to mark the spot where the string or tape overlaps. Slip it off your finger carefully.

Step 3: Measure
Lay the string flat and use the centimeter side of your ruler to measure from the start of the string to your mark. This measurement gives you the circumference of your finger in centimeters.

Step 4: Find Your Size
Entropic Jewellery rings are measured in EU sizes. Use our conversion chart to match your finger's circumference (in millimeters) with the corresponding EU size. If you're between sizes, we suggest sizing up slightly, as fingers tend to swell throughout the day.

Tips for Accurate Sizing:

  • Measure multiple times at different times of the day for the best fit.
  • Avoid measuring when your fingers are cold, as they tend to shrink in colder temperatures.
  • Measure the specific finger you want to wear the ring on—each finger is different!

Important:
For the most accurate sizing, consider visiting a local jeweler. They can determine your exact size, giving you peace of mind before your purchase.
