Rings - sizes, types and selection guide

Rings can sit very differently, even when they look the same. Here's a simple explanation of the types of rings in our range closed ring (one size) and open ring (adjustable) - and tips for choosing the right fit. We also go through what EUR size, width and wire thickness means you can shop for rings online with peace of mind.

A closed ring is the classic ring shape without an opening. It's made to fit exactly in the size you choose and typically provides a more "clean" and consistent fit.

Here you see some closed rings that have a fixed size and cannot be adjusted. The fit is therefore chosen based on the ring size that best fits the finger.

An open ring has a small opening that allows a little flexibility in fit. It can often be adjusted slightly to feel comfortable on the finger, which makes it great if you're fluctuating between sizes or if you want the ring to be a gift.

Here you see an open ring that can be adjusted slightly in size. This gives more flexibility in the fit and makes it easier to customize the ring to the desired finger.

What is the difference between a closed ring and an open ring?
A closed ring is a classic ring in one fixed shape that should fit in the size you choose. A open ring has a small opening that makes it more flexible and can often be adjusted slightly for a better fit.

What does EUR size mean?
EUR size is the European ring size, which is typically based on the circumference of the ring. When choosing a ring, the EUR size is the most important indicator of ring fit.

How do I know if I should choose fixed size or adjustable?
If you want a "secure" fit and a classic look, many choose a closed ring in the correct size. If you are unsure of the size or want some flexibility (e.g. when buying gifts), a open/adjustable ring be a good choice.

What does the width of a ring mean?
Width describes the visual "surface" of the ring - how distinctive it looks on the finger (the document describes width as the widest point of the ring).
