If you are not sure whether it is necessary to resize the ring, we recommend you ordering the ring without resizing. We regularly hear from customers that it turns out the ring fits. This is partly because you fit multiple sizes within a certain margin. After all, ring sizing is per quarter of a millimeter. Sometimes the ring fits on another finger or hand too, for example because the fingers of your dominant hand are slightly thicker. Also, temperature can be of influence. And there's a difference between a narrow and wide ring band: the larger the surface around your finger, the tighter the ring will be.
