I know! Buying a Ring online can become scary if you are not sure about your correct size! But honestly, there is no longer need to worry! There are a couple of simple ways to determine your size, as shown below, all from the comfort of your home! 

If you live nearby Zürich (Switzerland), and would like to personally come in the Atelier to discover your Ring Size, you certainly can do so! You simply need to send a message and make an appointment! 

If you do live far away and need any further assistance, you may also write a message and I will be glad to assist you!

Please note that at THAIZ JEWELLERY the American Standard(US) is used. If you know your ring size based on a different standard, please check the conversion chart below! 


One way to determine your ring size is by measuring it with an existing ring you already own. If you wish to do so, there are two methods you may follow: Measure the diameter of your ring with a ruler (as precise as possible), OR  print the image below at 100%, and follow the guidelines as described!

Once you discover the diameter of your existing ring, simply check the Ring Size Chart above ( "Inside Diameter"), and there you have your size!

Instructions: - Place a ring that fits over the circle, making sure the inside of the ring lines up with the outside of the circle.

- If you are between sizes, order the larger size.

- For the greatest accuracy, it is recommended to use a ring of the same shape, or as similar as possible!

Important: Regardless of which method you decide to follow, make sure the ring you measure fits correctly on the intended finger you are shopping for!

If you do not own a ring for the intended finger you are shopping for, you may also measure the circumference of your finger with a tape or cord! Simply wrap a cord on the finger you intend to wear the ring, and then measure the length of the cord with a ruler, as shown below:
