Firstly, GRRM himself tells us that the Reach is the strongest of the 7 kingdoms, and the Vale, the North and Dorne the least populated. Doran Martell himself acknowledges that Dorne is the least populous of all. So we have the Reach at the top and Dorne at the bottom in the lists of army sizes, and now we have to sort out the ones in between.
The Reach is high up on the top obviously. When Renly marched with his army he claimed to have 100,000 men, and Catelyn was shocked by the size of his camp. Of course, this comprised of some from the Stormlands, but given that he was marching up from the Reach, I think it's a safe bet that the majority of his army came from the Reach. Most of his key advisers in that march were Reach lords too. Besides, Mace Tyrell had kept back a significant portion of his army (10,000 IIRC), so I would judge the Reach's fighting strength as very, very high, probably between 80,000 and 100,000 men, and I would not be surprised if it exceeded 100,000.
After the Reach, I would put the Lannisters. Lord Commander Mormont called Tywin Lannister the most powerful lord in the Seven Kingdoms, and although that was probably partly because his daughter was the queen, I think the strength of the Westerlands must be a factor as well. When the Lannisters were fighting with the Starks and Tullys, Tywin outnumbered Bolton significantly at their first clash, and Jaime had 3 troops to Robb's 1 at the Whispering Wood. Let us not forget this was before Stafford Lannister was raising his "huge army" in the shadow of Casterly Rock. Catelyn also remarks that Edmure's army is smaller than Tywin's. So overall I would put the Lannisters at 2nd, I'm guessing their full fighting strength to be perhaps 50-60,000 men.
It's really hard to say who is 4th between the Riverlands and the Stormlands. They look about the same size on the map. The Riverlands should be pretty fertile with their rivers, but then the Stormlands may have monsoon rains too, as their name seems to indicate.
I just checked the Citadel information, and it seems the Riverlands has 42 noble houses while the Stormlands has 35. So my guess is that the Riverlands has slightly more manpower. Poor logic I know, but I really don't have anything else to go by. In any case, the Reach which is the most populous has the most houses, while Dorne, the least, has the fewest noble houses, so there is a slight basis to my logic.
I would guess their total fighting strength at somewhere around 35-40,000.
Next we come to the Vale and the North. Who has more? The North has 33 houses and the Vale 31, not enough difference to count. The North is very cold while the Vale is very mountainous, so both of them have less population than other kingdoms with the same area as them. (If the North had population corresponding to its area it could fight the other six kingdoms singlehandedly!) The Vale armies have not been seen in action, so there is really not much information on their fighting strength.
Very roughly, I would still guess the North to be slightly stronger, as they are just that much bigger in area. How many soldiers would they have in total? Robb brought 12,000 men south with him when he first marched, but so far we have all seen that after the first army marches out, the lords still have significant levies in reserve. (Note: the full figure should be 18000 when he had reached Moat Cailin, 1200 was the amount which had gathered at Winterfell, my mistake). Add to that the fact that the North is so huge so gathering armies takes longer, and that Robb's march was very hasty, I think probably the percentage of total fighting strength he brought out initially would be even less than the other Lords Paramount in the war. I think the total fighting strength of the North is somewhere around 25-30,000.
In that case, the Vale would probably be slightly lower, maybe around 25,000.
Dorne is the last of all, as admitted by Doran himself. I do wonder how he managed to hide that fact from the Iron Throne though, doesn't he have to pay taxes? It's difficult to gauge their power as they haven't really fought yet. But when the Iron Throne called for their help twice, once led by Baelor Breakspear and another time by Prince Lewyn, I noticed that Dorne always sent around 10,000 men. Maybe that is half their total fighting strength, which seems to be the rough percentage most Houses Paramount can call up on short notice. So I would put their full power at roughly 20,000.
Please share your opinions on my analysis born out of boredom!
