What is a comfort fit wedding band? A comfort fit ring is a style of band where the inside of the ring is smooth and rolls or “tapers” outward to the edge. This makes the band easier to get on and off, and makes it more comfortable in respect to movement of the fingers. A thicker band is necessary to create the roll of a comfort fit profile. Consequently, the drawback to comfort fit is that it’s more expensive. A non-comfort fit band has more of a square edge on the inside.
People who do a lot of work with their hands, people with larger ring sizes and people who are not accustomed to wearing rings often prefer comfort fit bands. Some people, however, don’t like the extra thickness because they feel like it makes the ring too bulky, while others quite like a heavier, thick ring. It’s much easier to feel the difference of comfort fit bands than to understand it through reading, so I suggest going into a couple of jewellery stores and trying on a variety of bands to see what feels best for you.
Here are some renderings to show the profiles of different band styles (1.5mm thick) in comparison with comfort fit bands (2mm thick). The following picture in Figure 1 shows, from the left: flat band with no comfort fit; a flat band with comfort fit; a half round with comfort fit; and a half round without comfort fit:
Below, you can see a cross section of two comfort fit bands – flat style on the left; half round on the right.
“Comfort fit” is a term that gets used a lot and can get confusing. Some people think that a half round shank is the same thing as a comfort fit shank. It is not. Either a flat band or a half round band can be made comfort fit… what is necessary is a thicker shank in order to accommodate the bevel on the inner edges of the ring.
Another misconception with respect to comfort fit bands is that a person’s ring size will need to change depending on whether the ring is a standard band or a comfort fit band. In fact, ring size should stay the same, regardless of whether the shank is comfort fit or not. A comfort fit band will go over the knuckle more easily, because it is so smooth, but the size of the finger where the ring will sit is a constant.
Finally, some people label comfort fit bands “Euro fit.” The original Euro-fit bands (also called ergo bands or ergonomic bands) were somewhat square in shape, and therefore “comfortable” in the sense that the bands did not spin around the finger or catch on things. Many retailers now use the term “Euro fit” and “comfort fit” interchangeably. The band in Figure 4 is both a Euro fit ring with a soft, square shank and a comfort fit ring with rounded interior edges.
Ultimately, the decision to go with comfort fit or non-comfort fit is a matter of personal preference and budget. The best way to determine which style is right for you is to try several rings on to see what you like.
