Measure A Ring

It would be awesome if you own a ring that fits you perfectly!

  1. Pick a ring from your collection that fits your desired finger.
  2. Measure inside diameter of the ring, from side to side (in mm) without the metal thickness.
  3. Check your size based on your measurement

Measure Your Finger

  1. A piece of string or dental floss is your best option! Wrap it evenly around the base of your finger you want to measure.
  2.  Mark the point where the string end meets.
  3. Measure the distance of your string from the start end to your mark point with a ruler (in mm).
  4.  Leave some room if your knuckle is larger than the base of your finger, or you can repeat the process around your knuckle, ensuring you measure it tightly. If you are in-between sizes, size up.
