Forum:Number of hogwarts Students?

In the Hogwarts article It says there is roughly 1000 students attending Hogwarts at any given time. However later in the article it says there are about 40 students per year. If you multiply 40 students by 7 years there would only be around 280 students total. This seems like a more reasonable number than 1000 for multiple reasons: 65.49.26.206 19:57, 19 July 2009 (UTC)
 * assuming the great hall is a size comparable to a large high-school cafeteria it would comfortably hold about 300 people at one time.
 * if the common rooms were a reasonable 400 square feet, they could hold about 70 students(10 students * 7 years) plus furniture. Although this would be a cramped situation the books make the parties in the Gryffindor common room, after the quidditch victories, sound as if they are cramped.
