Size Guide

Patience and care are worthwhile when determining ring sizes.
We have therefore put together some tips for you on how to measure your sizes as reliably as possible.

Measuring with metal trial rings
As fingers react to temperatures and other factors and can change their condition over the course of the day, in our experience the most reliable way to determine sizes is with a set of metal (not plastic) trial rings (e.g. this one). 
It is advisable to wear the rings in the morning and evening (possibly also at night) for a longer period of time. In this way, you can develop a feeling for the right size.
We recommend separating the individual rings from the band. This requires some force, but it is worth it when determining the size.

Please keep in mind that the width of your final (wedding) ring also influences the size that you need. Generally we can say: the wider the ring rail, the bigger the ring size (as the ring covers more of your finger).
Each sample-ring from this set is about 2 mm wide, so if the ring width is e.g. 5 mm, we recommend to rather take half to one size bigger for your wedding ring than the determined size from the trial rings.

When determining the ring size, please always use a ring and NOT something flexible to measure, as this can lead to major inaccuracies!
Flexible measuring tools such as plastic measuring tapes for the fingers are unfortunately not very precise. The measuring tapes are usually much wider than the (wedding) rings and do not simulate a realistic wearing experience. In addition, a flexible measuring tape does not have a perfectly round diameter, so incorrect ring sizes can be determined.

Measuring with a well-fitting ring
Determining the ring size from the inside diameter of a ring can be somewhat inaccurate, as a difference of 1 mm can make a difference of approx. 3 ring sizes (see table below).
We therefore recommend that you either measure very precisely with a caliper gauge (including tenths of a millimetre) or send us a suitable ring.
In this case, please make sure that the ring has a similar width and fits the finger on which you would like to wear your Cirer ring.

Measurement in a goldsmith's shop or at a jeweller's
You can also have the sizes measured at a goldsmith's or jeweller's (preferably with rings of a similar widths).
However, please bear in mind that this is usually only a snapshot and that fingers can change.
