How to use the downloadable ring sizer

1. Scale

Before printing, ensure this guide is set to print at 100% scale and that you are printing on standard A4 paper (210mm x 297mm). 

If you are unsure as to whether you have printed the correct size, or if you are measuring on a screen, place a credit card between the arrows on the guide.

2. Use an Existing Ring

The easiest way to work out your ring size is to use an existing ring. Simply match the inside of the ring to one of the circles below.

You should only be able to see the circle inside of your ring and little to no white paper.

3. Cut out Sizer

If you don’t have an existing ring, cut out the paper ring sizer along with the CUT LINE.

After you cut out the ruler wrap it around your finger with the numbers visible. The number that appears closest to the opening is your ring size. Try moving the ruler across your knuckle, we recommend selecting a size that goes on and off your finger easily. 

Please note, ring size may vary.
