crusader-kings-2
I really enjoy the diplomacy, marriage, and plot options in Crusader Kings 2. I'm after options and ideas on ways to expand my realm in this game without war. Examples from games you've played would be awesome if you have them. I find it more fun to scheme sometimes as war can be a bit straight forward (it also wrecks havock in my levies for some time – somehow I always get called to war right after a personal war of expansion).
Oh, it wouldbe helpful to list which DLC you need if applicable.
If you want to find out the size of a single realm, I would go the way bd33 suggested.
But if you want to get an overview of the sizes of all realms, go to ledger:
Then get to its tenth page (“Independent States”) and click on the “Realm Size” column heading to sort the list by that:
Give demense holdings to your heir, then make him independent. When your character dies, you should have it all again. Also note what svick says in the comment on the question above:
You can always grant independence to some of your vassals. And if they are part of your de jure realm, it should be relatively simple to get them back (but I haven't tried it).
You can just request them to be your vassal, or press a du jure claim on their territory after you want to grow again.

One strategy is to find an unlanded noble who is in line to inherit a title outside your realm, invite them to court, and then grant them a title within your realm that is of equal or higher rank than the one they're set to inherit (i.e. if he's inheriting a county you can't just give him a barony). If the other realm has crown laws set to medium or lower, then the title will fall into your kingdom when they inherit.
