Save the date: popular nickname or full name?

I used my nickname for my STDs and wedding invitations. I don't go by my given name at all. The only time it was used was in the ceremony and of course, the marriage license!

FH goes by his middle name. On both STD and invites we used his middle name. My family, except immediate, wouldn't know who the hell I was marrying if I put Stephen.

My FH is Christopher but goes by Chris. STDs said sagan and Chris but invitations use full first/ middle names

Thanks everybody! That's what I wanted to do but I wasn't sure if it would be weird to send out an invitation listing different names than on the STD!

Our names are Elizabeth and James, and there's a bunch of James and Elizabeths in our family so without including middle and last names, putting Ellie (of which I am the only one) might help lol

I feel there's only very few times to use your given name so I used my full name.

I used Katie (which is what I go by) on the STDs. However, I used Katherine for the more formal invitations.

I have a similar problem because I have a double barreled first name, but everyone just calls me Lyla other than for work/formal events. However, I decided to do my full name in our STDs. That's because I knew I would use my full name for our formal invitations and documents. I didn't want people to have to search under both my nickname and full name for our wedding website and registries. By keeping it consistent, I think it will be easier for his side. Maybe you could just be Ellie on the website, invites, and registry too?

I am in the middle of a legal name change and will be using a nickname everyone knows me by as a compromise and to not confuse my grandparents.
