How To Determine Your Ring Size
Follow the steps below to determine your Ring Size approximately.
Please note that the ring size you get is only approximate. You
should consult a jeweler to determine your ring size accurately.
Directions
1. Print out this page. (Make sure that the “Fit to Page” or “Scale to Fit” options are not selected.)
2. Cut out the Ring Sizer below and make a slot by cutting along the dashed line.
3. With the numbers to the outside, insert the black end through the slot.
4. Place the Ring Sizer over your finger and pull the tab through the slot until it fits comfortably.
5. Read the corresponding size from the scale as it lines up with the edges of the slot.
