Find my ring size
Method 1: Using a ring (diameter)
- Pick a ring that fits the finger you want.
- Measure the inside diameter of the ring in mm.
- Use the size chart above to find your size.
Method 2: Using your finger (circumference)
- Cut a piece of string or paper strip (about 10 cm).
- Wrap it around your finger where the ring will sit — not too tight.
- Mark where the ends meet.
- Measure the length between the two marks in mm.
- Use the size chart above to find your size.
Expert tips
- Measure the correct finger — the same finger on the opposite hand can differ in size.
- Always measure twice.
- Measure in the afternoon when your hands are warm for the most accurate result.
- If you're between sizes, size up.
