"I haven't drawn [a floorplan of Hogwarts] because it would be difficult for the most skilled architect to draw, owing to the fact that the staircases and the rooms keep moving. However, I have a very vivid mental image of what it looks like."
-- J.K. Rowling (Sch1)

"Maths is not my strong suit, though it's better than my geography..."

Atlas of Hogwarts

Here in the Atlas of Hogwarts we’ve collected a variety of maps and other artwork which depicts the castle and the area around it. With the exception of Rowling’s own map, none of these maps can be considered canon. Some of them predate the revelation of Rowling’s own sketch map on the DVD of Prisoner of Azkaban, so they represent the best guesses of fan artists who had nothing to go on but Rowling’s amazingly descriptive prose. Others serve to illustrate the films or games. All are fascinating in their own way.

Notes

The maps in the Atlas are meticulously researched from the Harry Potter books. In some cases, actual maps of real places are used as a reference. But these maps are not canon; they are essentially fan art. There is no way to draw maps of anything from a book and have them be 100% accurate. They are as accurate as I can possibly make them with the information available. I have included lists of references from the books below many of the maps so you can see why I made the choices that I did.
