The best way to find your ring size is to visit a jewelry shop and ask them to measure it for you using a special tool. If this option is not available to you, here is another way. 

Take a ring that fits comfortably and measure its inside diameter (the distance at the middle part of the circle). Then check in the chart below what this means in terms of ring size. 

TIPS:

  • If you are between 2 sizes, order the bigger one. 

  • Measure a ring that is similar in thickness as the one you wish to buy. Your thicker rings are usually 1 or 2 sizes bigger than your thinner ones. 

  • If you know your knuckle is on the larger side, order half a size bigger than what your measurement indicates otherwise you won't be able slide your ring into the right place.

  • We do not advise that you use the various printable guides that you may find online nor a piece of paper wrapped around your finger, as they are not very accurate.
