Leo as a standalone or short for...?

bananers

I like Leo. Not a fan of Leonardo. Maybe Leonard. I tend to prefer names that have a more "formal" version, but I also know Leo also is a legit standalone name. Would you just go with Leo, or would you make it short for something, and if so, am I missing any others besides the ones mentioned above?

I like Leopold.

I love Leo by itself or as a NN for Leopold.

I would just go with Leo. It's cute.

I like just Leo. I think it is a great stand alone name

I'd stick with just Leo.

Leo is on our list too! Stuck on middle names though.

DD is in a class with two kids who go by Leo (of all the names to have duplicates of...).  I think one is Leonardo and one is Leo.  If you prefer Leo to Leonard, Leonardo, etc., then just stick with Leo.

My nephew is Leo and he was named after my grandfather and great grand father

I like it as a standalone name.

I would use one of the longer versions

I like all of the longer options (Leonardo, Leonard, Leopold).  I'm iffy on the name as a stand alone.  It totally depends on what your other options are, generally these will be my last choice.

Leon (french)

Leonidas  (greek, king of sparta) -- I know a little Leo with Greek ancestry, this is his full name.

AsOctoberFalls

I'd go with Leonidas.

I don't like Leo as a standalone.  It's too nicknamey/informal for me.

I would just use Leo.

But then again I named my kid Abe, not Abraham, Abel, etc..
