Ring Sizing
A ring should slide on with a little resistance and feel secure but comfortable. Here's how to find your size with confidence.
— Best Option
Get Measured by a Jeweler
The most accurate way to find your size is to have your finger measured on a proper ring sizer at a local jeweler — it takes a minute and most will do it for free. If you can, this is always our first recommendation.

Measure an Existing Ring
Take a ring that already fits the correct finger and measure the inside diameter across the center in millimeters. Match that measurement to the chart below to find your size.

The String or Paper Method
Don't have a ring to measure? Try this:
- Wrap a thin strip of paper or a piece of string snugly around the base of your finger.
- Mark where the end meets, then lay it flat and measure the length in millimeters.
- That length is your finger's circumference — match it to the chart below.

— Tips
For the Most Accurate Result
- Measure at the end of the day, when fingers are at their largest.
- Make sure your hands are warm — cold fingers measure smaller.
- If you're between sizes, size up.
- Wide bands fit more snugly, so consider a slightly larger size for them.
