Ring Size Guide
Getting your ring size right matters โ a ring that is too tight is uncomfortable, and one that is too loose can slip off. Here is how to measure at home accurately.
How to Measure Your Ring Size
- Use a strip of paper or thin string. Cut a strip no wider than 1 cm. Wrap it around the base of the finger you want to wear the ring on.
- Mark where it meets. Use a pen to mark the point where the strip overlaps to form a complete circle.
- Measure the length. Lay the strip flat and measure from the end to your mark in millimeters. This is the circumference of your finger.
- Find your size in the chart below.
Before you measure:
- Measure at room temperature โ fingers shrink when cold and swell when warm
- Measure at the end of the day when fingers are at their largest
- If your knuckle is larger than the base of your finger, measure the knuckle too and size up

Tips
- Between sizes? Go up half a size โ a slightly loose ring is more comfortable than one that is too tight, and easier to remove.
- Dominant hand fingers are often slightly larger than the other hand. Measure the specific finger you plan to wear the ring on.
- Knuckle check: if the ring slides over your knuckle easily but feels loose at the base, try a half size down.
- Not sure? Order two adjacent sizes and return the one that does not fit โ see our Returns & Exchanges policy.
