Simple plain bands can usually go up one or two sizes. Beyond two sizes you risk weakening the band or distorting settings. Thin bands under 2mm are hard to resize at all. Eternity rings and tension settings cannot be resized. Cost is 20-60 dollars depending on complexity.

Most women in the US are a size 6 or 7. If she is average build, guess 6.5. If she is petite, 5.5-6. If she has larger hands, 7. You can also borrow a ring she wears on her ring finger and press it into a bar of soap to make an impression.

Wedding band width comes down to hand size and style. For women: 2-3mm is delicate, 4mm is classic, 5-6mm is bold. For men: 4-6mm is standard. Wider bands fit tighter, so size up half a size for bands over 4mm.

    I disagree because I had the opposite experience.
