Bride doesn't want me the maid of honor standing next to her at the ceremony

That makes no sense. Even when I’ve seen people arranged by height, the MOH and Best Man are still closest to the bride and groom.

Makes no sense. I would be offended and ask her why she even wanted you to be maid of honor then.

That honestly doesn't make sense ... especially since, for example, my MOH is wearing a different color dress from the rest of my bridal party. If I put her anywhere that's not first or last in line, it would look odd. But MOH and BM should always be closest to the bride and groom... Maybe just express your feelings about it. Or suggest she make a post on WW about her decision and maybe it'll help her see that typically that's not how it's done.

That’s a little nuts. Maybe ask her if she talked to her officiant? I know in a catholic ceremony, everything must be in order... and that means MOH and best man next to the bride/groom. The rest of the BMs she can pick what she wants

Yes. You need to clarify this with her. Why even bother making you MOH then???

Yeah this is odd.

MOH always stands next to the bride

This is definitely odd and I would mention something but I wouldn't fuss over it if she doesn't change her mind. Honestly, it wouldn't make a difference to me if people didn't know if I was MOH or bridesmaid, which seems like the worst that can happen if she continues with her height order philosophy.

Ah, a bride that places more importance on her "vision" rather than etiquette. With luck, the officiant will require that the MOH stand next to the bride.

Gosh some women are so misguided. I’d address it and if she insists on being weird about it I’d drop from the wedding.

I would be offended because she's more worried about how "perfect" her photos will look versus having her MOH by her side. But not offended enough to drop out of the wedding, it's a little silly to insist on standing next to her. People will ask her why you aren't standing next to her and will probably set her straight so I wouldn't worrya bout it yet.

Very weird - but I wouldn't make too big of a deal about it. Let her know your thoughts but ultimately its her wedding and she can break tradition and do things how she wants to.

My friend did the height thing at her wedding but the MOH and BM stood beside the bride and groom.
Why bother making anyone MOH if you’re going to arrange by height?

That makes no sense at all. The MOH always stands next to the bride, that's the whole point of being the MOH. Like @Sarah said, if the couple wants the wedding party to be arranged by height, they still have the best man and MOH right next to them, and only the rest of the WP are arranged by height.
