The width of a woman's wedding ring depends entirely on the width of the band on her engagement ring. If a woman with small hands already has a large, wide engagement ring, choosing a narrower band for her wedding ring is a better choice for her comfort. A woman with larger hands can handle wider bands on both engagement and wedding rings, but might prefer not to. At this point, it is a choice you can make together. Women's wedding rings traditionally match their engagement rings in some way, but they can be very different widths and look beautiful together.
