Finding your ring size at home is simple. Follow the steps below to measure accurately — a well-fitted ring should slide on with gentle resistance and come off with a little effort.
Method 1 — String or Paper Strip
- Cut a thin strip of paper or use a piece of non-stretchy string.
- Wrap it snugly (not tightly) around the base of the finger you plan to wear the ring on.
- Mark where the paper or string meets. For string, mark both the wrap point and the end.
- Lay the strip flat against a ruler and measure the length in millimeters — this is your finger circumference.
- Find your circumference in the chart below to identify your US ring size.
Tips for the most accurate measurement:
Fingers are slightly larger at the end of the day and in warm weather — measure then for the best fit. For knuckle-fit rings, measure the widest part of your knuckle. If you fall between two sizes, we recommend sizing up.

Method 2 — Measure an Existing Ring
- Find a ring that already fits the intended finger well.
- Measure the inside diameter of the ring in millimeters using a ruler.
- Match that measurement to the diameter column in the chart below.

Still Not Sure?
We recommend visiting a local jeweler for a professional sizing. Most offer this service free of charge. You can also order two adjacent sizes and return the one that doesn't fit — see our return policy for details.
