👑 How to Measure

💎 By Ring Diameter

Measure the inner diameter of an existing ring that fits well using a ruler.

📏 By Ring Circumference

Wrap a string around your finger, mark where it overlaps, then measure the length.

✋ By Finger Measurement

Use a flexible measuring tape around the base of your finger.

✨ Measurement Tips

  • Measure your finger at the end of the day when it's at its largest
  • Ensure the ring can slide over your knuckle comfortably
  • Consider the width of the band - wider bands need larger sizes
  • Your dominant hand is usually 1/2 size larger
  • Temperature affects finger size - avoid measuring in extreme temperatures

💡 Note: Ring sizes can vary between manufacturers. When in doubt, visit a jeweler for professional measurement.
