Fred Wilson has a great, descriptive post on how he thinks about deal size in the context of his fund (Union Square Ventures.)  The “Brad” in the post is Fred’s partner Brad Burnham.  Overnight I received a question from someone about “typical deal size” – I couldn’t have answered it better than Fred did – who clearly demonstrates in his post that it is firm specific.  If you want to get inside the brain of an early stage VC (e.g. have your own Being John Malkovich moment), read Fred’s post.
