 Ring Measuring Directions
  1. Wrap a thin strip of paper around the base of your finger. If you have thick knuckles, measure the knuckles too (you may want to choose a size between the two to allow the ring to slip on comfortably.
  2. Mark the spot where the paper meets.
  3. Measure the paper's length with a ruler.
  4. Use the chart to determine ring size.
Ring Measuring Tips
The thicker the ring, the tighter the fit, so if you choose a ring with a deep band width, you will likely need to go one size up. The best time of day to measure is in the evening, when your fingers are largest. Avoid measuring when you’re cold, as fingers are at least half a size smaller.
