Ours is about 50. Sadly, the only ones from my side are likely to be my two girls. The good news is, I love his family and they love me too, so that eases the sting quite a bit.
I'm planning on inviting about 100. I've started a guest list and I got to about 90, so I'm thinking about 100. I have a big family. Probably 50 of them are just my moms side of the family: aunts, uncles and cousins.
