Nah. I've seen enough larger cover books to qualify the Historia as a medium book. A3 geography books are rather common, which is one and a half times the overal span of the Historia book and come in hard cover. They can get pretty heavy too.

Maybe it's just a difference in culture. I think of A4 as medium, a standard sized book. A5 and A6, the normal sizes for novels, are small books because they are designed to be put in a bag and taken with you, and B6 and under are tiny books, and usually not that thick. A3 and over are large books because they are generally specialised, either as text books or childrens picture storybooks.
