In Crusader Kings II, Catholic rulers can ask the Pope for a licence to ki-- er, invade, and take the top-level title (Duke, King, Emperor, God-King, etc.). You can only do this to invade people bigger than you, so your best bet is to build up your realm until you're just slightly smaller than the other guy and then request the invasion. How do you tell when you're just a little smaller than the other realm? There's a nice number in the upper-right corner of the screen that tells you what your total realm size is, but how do you find it for other rulers?

    just wanted to comment, after looking at this question and checking the questions in the "crusader-kings" tag, I will be picking this up tonight :)

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:

Ledger button

Then get to its tenth page (“Independent States”) and click on the “Realm Size” column heading to sort the list by that:

Click on the Realm Tree on the right side of the character portrait of someone in the realm you want to invade.

There are two numbers: a percentage (relative strength, which you can hover over to see Levy numbers) and the number of holdings. Hovering over the bottom number reveals how many the individual holds (Demense) and how many their vassals hold. Go to the character at the top of the realm tree to see that information for the entire Empire/Kingdom/Duchy.

    BTW, it seems you uploaded your images to imgur.com manually. That's fine, but there is an easier way: click on the image icon above the edit box.
