Size Guide - The Payment Ring

Don't know your ring size?

Minimize the trouble of ordering the wrong ring size. Please follow the instructions below carefully. If you still feel uncertain, it's better if you choose the "I don't know my ring size" option under product size. We will then send you a ring measurement tool, for testing at home. 

1. Measure your finger

One of the easiest ways to know your ring size is to measure your finger with a string or strip of paper.

  1. Start by cutting out a strip of paper that is approximately 0,5 cm wide and 10 cm long. Wrap the paper around the base of the intended finger. Make sure to pull it really tight, since the base of the finger normally is very flexible.
  2. Make a mark where the paper overlaps with a pen. The length of the paper you measured in millimeters is the perimeter of your finger.
  3. After finding this measurement, use our conversion chart to find the corresponding ring size. If you have made the measurement technique above and end up between two sizes we recommend going for the smaller size.  

If the size of your finger below the knuckle drastically differs in size from the knuckle itself, measure your knuckle as well and choose a size that falls more in the middle of these two measurements.

 

 

2. Measure a ring you already have

If you have a ring that already fits your finger well, you can use a ruler to measure the inside diameter of this ring. Just take your ruler and measure straight across the inside of the ring from edge to edge. Take the diameter measurement in millimeters, and then use our measurement-conversion chart to find your ring size.
