Ring Size Guide

How to Determine Your Ring Size

  • Use a string or paper strip: Wrap a piece of string or a paper strip around the base of your finger. Mark where the ends meet, then measure the length with a ruler. This is the circumference of your finger.
  • Compare with a size chart: Use the circumference you measured and compare it to a ring size chart to find your corresponding size.
  • Consider temperature and time of day: Your finger size can fluctuate slightly based on temperature and time of day, so it’s best to measure your finger at room temperature, in the evening when your hands are warm.
  • Visit a jeweler: If in doubt, visit a local jeweler to get professionally sized for the most accurate result.

Additional Tips and Tricks

  • Measuring for a custom fit: If you are ordering a custom ring, consider measuring your finger at the time of day when your fingers are at their normal size.
  • Adjusting for knuckle sizes: If your knuckle is significantly larger than the base of your finger, it's recommended to measure both the knuckle and base of the finger to choose a size that comfortably slides over the knuckle.
  • Avoid tight rings: A ring that’s too tight can be uncomfortable and hard to remove. Aim for a snug but comfortable fit.
