Well, I'm not altogether sure about that. Mind you, I don't have any excavated samples with me, but I'm of the mind, given the amount of strength and exercise that was needed to become and continue to be a knight, these were not small men. They may have been short, but not small.
If Allan was still in business, he would be the man to see...I still think I got over as the armor he's made for me was to my measurements, but at off the rack pricing. There is only one other armourer out there that could compare with his prices (but not his quality as far as I'm concerned, this guy's a bit more...utilitarian in design). Not that his quality is low, he puts out good, servicable wares...it just won't be as pretty. Considering your persona is landless/poor knight, it should be right up your alley. Here's his site, pointed right at the leg portion of it:
