The Simplified Sizing Guide

We understand the frustration in ordering something online, hyping up its arrival and then having it not fit quite how you anticipated. Thus, we aim to make the sizing procedure hassle and mistake free - meaning your first ZONDER order will fulfil the hype and be the perfect fit. 

All of ZONDER's ring sizes are in US sizing. Please note: visiting a local jeweller will always be your best bet for the most accurate sizing. 


If you have access to a printer:

  1. Ring-click the image above and select 'Save Image As'
  2. Print the image at 100% scale (ensuring scaling is switched off)
  3. Measure the bottom box section - it should be 3.5 inches or 8.9cm from end to end. 
  4. Cut out the sizing tool (top section) and wrap the piece of paper around the desired finger. 
  5. The number that aligns with the 'Read Size Here' line will be your US size. (Note: if you are between two sizes; it is best to round up a size, rather than round down.)


If you do not have access to a printer:

  1. Cut a thin strip of paper, about 10-12cm long
  2. Wrap the strip of paper around the base of the desired finger
  3. Using a pen or pencil, mark the point at which the paper overlaps itself
  4. Lay the strip of paper on a flat surface and a use a ruler to measure (in millimetres) the distance from the end of the strip to the marking you made. This will give you the circumference of your finger
  5. Using the chart below, convert your measurement to the standard US ring size
  6. If you are in between sizes, it is always best to round up rather than down



Measuring Tips

  • Allow enough room to accomodate for your knuckle
  • Bear in mind that the same finger on the opposite hand may have different measurements
  • Make sure your body is at a normal temperature as this can affect the measurement
