Processional order

No one will feel hurt. Visually it will look better in photos if your BMs are lined up by height. It's pretty normal to do it that way.

I paired mine up with my groomsmen even though they’ll be walking separately. I tried to think who would work best opposite the other especially since a couple of my BM are married to the GM! For the ones not married, I just did it by who I’ve known longest/am closest to but obviously won’t tell them that.
I don’t think anyone should get offended at being furthest from you, they should be honored to be up there on your special day!

heres my line up (though I do have MOH)
matron of Honor sister 1
maid of Honor sister 2
best friend of 23 years
best friend from college who I talk to literally daily
Best friend from HS
Future sister in law

You can do it however you’d like. Most of my friends have had the person they’ve known the longest stand closest to them and the person they’ve known the least amount of time stand last. There’s no right or wrong way.

I didn't want anyone to feel as if one was more important than another so I lined up my girls by height. It looked nice in pictures as well. Luckily my MOH was the shortest so it made the decision easy as it just worked out.

I am lining my girls up by my 2 MOH closest to me then the other 3 will follow. As for the processional, we will have them come in in the reverse order. I like the reverse order as my nephew will be the ring bearer and will likely be walking with my sister(his mother) who will be walking last.

I honestly can't tell you how my friend ordered us cuz I don't think it was really height and definitely wasn't alphabetical. I think she just decided by who she knew the longest I guess after her MOH. Lol I am trying to do by height as to not piss anyone off and they'll hopefully realize it's by height.

Do it how you like! No one will be hurt. But height order can yield nicer photos. And no, they don’t have to walk with groomsmen
