Option 1: Measure a Ring You Already Own

1. Choose a ring that fits the finger you want to size.

2. Use a ruler or caliper to measure the inner diameter (in millimeters).

3. Match that number to the sizing chart (left).

Option 2: Use a Paper Strip

1. Cut a thin strip of paper or string (about 3-4 inches long).

2. Wrap it around the base of your finger — snug but not tight.

3. Mark where the ends meet.

4. Measure the length in millimeters.

5. Use the chart (left) to find your size.

Option 3: Use Tools

Pro Tips for Sizing

• Measure at the end of the day — your fingers are slightly larger.

• Cold weather shrinks fingers; warm weather can swell them.

• If you’re between sizes, I recommend sizing up for comfort.
