Standard Fit Rings versus Comfort Fit Rings
Standard Fit rings have a straight inside edge. They do not have the extra domed shape on the interior that Comfort Fit rings have. Standard Fit wedding bands have a very
minimal rounding of the interior edge, just enough to not be sharp when worn on the finger.
Comfort Fit wedding bands are manufactured using extra metal to create a dome on the inside edge of the band resulting in a more comfortable fit. The center part of the ring fits closer to the finger than the outer edges. A comfort fit ring will fit looser on the finger because it is not flat on the inside but rather rounded.
Comfort Fit bands are much more comfortable to wear, allowing for more movement of the finger. Only the smallest point at the center of the interior dome is true to size. Therefore comfort fit bands are slightly larger
that regular fit bands of the same size.
