Ring sizing guide
Your best bet for landing on the right ring size – and avoiding annoying returns – is to borrow an existing ring that fits the ring finger on her left hand. Just measure the internal diameter of the ring in millimeters, then find the corresponding ring size in our chart below.
If you don’t have a ring to compare to:
- Wrap a thin strip of paper (or floss) around your finger where you’d like your ring to sit.
- Make sure that the paper is pulled snug to your finger.
- Mark the spot where the paper meets, and measure the distance in millimeters with a ruler.
- Use the below chart to find the corresponding ring size.
