Ring Size Guide
Measure your Ring Size
Here in New Zealand, we mainly use the UK letter ring size system, but as long as you know your size in any recognized system then we can make the perfect ring for you. All our precious metal rings are available in every size, because we make each one to order!
When ordering on our site choose your closest size in USA, UK or European standard ring sizes. For in between sizes choose the closest size, add to Cart and put your exact size in the Special Instructions box on the Cart page. Remember you can email us after you place your order if you have any concerns.

You don't know your ring size already?
No problem! If you don't already have a ring, a local jeweller will normally measure you for free.
Or, see if you can borrow one that fits perfectly. Then go to www.findmyringsize.com and in just a few seconds you can find out your exact size. Make sure the borrowed ring is about the same width as the ring you are considering choosing, as width can make a difference to fit.
Other Ring Size Systems
We would recommend the Wikipedia Ring Size page if you want to check further.
When is the best time to measure?
The thickness of your fingers vary during the day. We recommend you measure your ring size during the evening, at room temperature (approx. 20ºC/68ºF).
Ring Size Chart
You can also measure an existing ring against our Jens Hansen Ring Size Chart
Note: Please make sure to print it out at 100% scale and check with a ruler that the scale is correct before you use this chart.
