Do I need a different size for a comfort fit band?
You may need a different size depending on the band width, interior profile and maker. Use the makerās sizing guidance and try a sizer that matches the intended width and fit rather than applying a universal conversion.
Is comfort fit only for wide bands?
It is most noticeable on wide bands, where a flat interior has the largest contact area and the hardest passage over a knuckle. It is made in narrow widths too, where the difference is real but smaller.
Does comfort fit change how the ring looks?
No. The dome is on the inside. Two bands of the same width and finish can look identical from the outside and differ only in how they feel and what size they take.
Does a comfort fit band weigh more than a flat one?
It may not. The domed interior takes metal away along the inner edges and adds it toward the centre, and which way that nets out depends on how the maker cuts the profile. Where a listing states a weight you can compare directly; otherwise a jeweller can weigh it.
