Choosing a ring that fits you perfectly is easy if you know your size. Here are two simple methods for measuring it at home (without having to run to the jewelry store).
✂️ Option 1: Use paper tape
- Cut a thin strip of paper (about 5 mm wide).
- Wrap it around the base of the finger where you will wear the ring.
- Mark the point where it crosses.
- I measured it with a ruler in millimeters. That measurement is the inner circumference of your ring.
📌 Tip: Find your size in our chart below by comparing the circumference.
💍 Option 2: Measure a ring you already have
- Choose a ring that fits well on the finger you want.
- I measured the internal diameter (side to side, inside the ring) with a millimeter ruler.
- Compare with our size chart.
🧠 Useful tips
- If you are between two sizes, we recommend choosing the larger size.
- The ring should fit comfortably: not so loose that it falls off, nor so tight that it is uncomfortable .
- If your finger changes a lot with cold or heat, take the measurement at a neutral time of day.

📌 Instructions for Using the Chart:
- Circumference : Measure the circumference of your finger in millimeters using one of the methods mentioned above (paper tape or measuring a ring you already own). Compare the result to the Circumference column .
- Diameter : If you prefer to measure a ring you already own, use the inner diameter . Compare to the Diameter column .
