Find Your Size at Home
No kit needed. Use these simple methods to determine your ring size, ideal chain length, or bracelet fit — all from home, before you bring or send your piece to us.
Measure a Ring That Already Fits
This is the most accurate method. Place a ring that fits well on a ruler and measure the inside diameter in millimeters. Enter it below to find your US size.
Paper Strip Method
- Step 1. Cut a thin strip of paper about ½ inch wide and 4 inches long.
- Step 2. Wrap it snugly around the base of the finger you want to size. It should feel comfortable — not tight.
- Step 3. Mark where the paper overlaps with a pen.
- Step 4. Lay the strip flat and measure the length in millimeters — this is your finger circumference.
- Step 5. Divide by π (3.14159) to get the diameter, then find your size in the chart below.
Tip: Measure at the end of the day when your fingers are slightly larger. Avoid measuring when cold.
