Comfort fit wedding bands are crafted using extra metal to make the inside of the band slightly domed, resulting in a very comfortable fit.
Comfort-fit bands are especially recommended for men, because they are easier to squeeze over a large knuckle when putting your ring on or taking it off, and it's much more comfortable to wear once it's on.
Standard fit bands have a straight interior, and do not have the extra dome of metal provided by comfort fit wedding bands.
This drawing shows a cross section of a heavy domed wedding band featuring a comfort fit. Notice that the comfort fit on the inside of this ring is the same as the ring shown in the top picture, but the outside dome on this ring is higher. This illustrates the difference between “Domed Comfort-fit” and “Heavy-Domed Comfort-fit” wedding bands.
Here is a flat style wedding band showing a comfort fit.
Many wedding bands are available in a comfort-fit style, which means the inside of the band is slightly domed, resulting in a very comfortable fit. The comfort-fit is especially recommended for men, because it is easier to squeeze over a large knuckle when putting on or removing a wedding band, and the ring is much more comfortable to wear once it's on. Comfort-fit wedding bands made with precious metal such as platinum and gold are a little more expensive than non-comfort-fit wedding bands. This is because of the extra precious metal required to make the inside of the ring domed. Alternative metal wedding bands such as tungsten and titanium automatically come with comfort-fit styling at no extra charge.
We strongly recommend comfort-fit styles for widths of 5mm and wider. On widths of 4mm or less, the comfort-fit advantage is not as noticeable, but because the rings are still more comfortable than standard wedding bands, we recommend the comfort-fit for all widths if your budget allows.
