Collect a strip of paper, a pen/pencil and a ruler.

step two

Wrap the paper strip around your finger so you make a “ring”.

step three

Once you have the paper fitted, use the pen/pencil to mark where the edges overlap.

step four

Now, measure the length of the ring using the ruler and compare it to the chart.

find your ring size using a ruler

  1. Select a ring that properly fits your ring finger.
  2. Measure the inside diameter of the ring in millimeters.
  3. Once you have your measurement, refer to the sizing chart to get your ring measurement. 

Use Ring Sizing Tool To Measure Your Ring Size

  1. Print out the sizing chart. When you do so, make sure you're printing at *100% size. Any larger or smaller and your measurement will turn out inaccurate.
  2. Use a pair of scissors to cut out the sizer.
  3. Gently slice through the line between the black 'READ SIZE HERE' arrow and the letter 'A'.
  4. Insert the tapered end of the sizer through the slit to create a ring.
  5. Place the ring on your finger and pull the tapered end of the sizer until the ring fits comfortably on your finger. Make sure it is not too tight/loose.

Measure Your existing ring

  1. Print out the sizing chart. When you do so, make sure you’re printing at *100% size. Any larger or smaller and your measurement will turn out inaccurate.
  2. Take a ring that best fits your finger and place it on each circle until you find one that matches the size. The black circle should fill the ring entirely
  3. Open up your printer dialogue box and look for the ‘scaling’ settings. Make sure it’s set at “none” or uncheck the box for page scaling.
