How to Measure Your Ring Size
Finding the right ring size helps your jewelry feel comfortable, secure, and easy to wear every day.
Please follow the guide below to measure your ring size at home. For the most accurate result, we recommend measuring your finger more than once.
Before You Measure
Your finger size can change slightly throughout the day. For best results:
- Measure at the end of the day when fingers are at their normal size.
- Avoid measuring when hands are very cold.
- Avoid measuring right after exercise, alcohol, or salty foods.
- Measure the exact finger where you plan to wear the ring.
- If your knuckle is larger, choose a size that slides over the knuckle but still fits securely.
Method 1: Use a Ring You Already Own
- Choose a ring that fits the finger you want to measure.
- Place it on a flat surface.
- Measure the inside diameter from one inner edge to the other.
- Compare with the size chart below.
Method 2: Measure With a Strip of Paper
- Cut a thin strip of paper.
- Wrap it around the base of your finger snugly.
- Mark where the paper overlaps.
- Measure the length in millimeters — this is your circumference.
- Compare with the size chart below.

Between Two Sizes?
If your measurement falls between two sizes, we recommend choosing the larger size. For wider bands, go half a size up. For thin bands, your regular size works best.
