How do the dormitories work? because i only see the two doors (one to the boys dormitories and one to the girls)in the movie and only 5 boys r in the boys. Does anyone know please help me understand

Most likely when bạn open the door there will be thêm rooms inside of the door. And each of the rooms have five students. And I'm sure it goes upstairs for a few levels so...hope this answer helps. :)

The layout is as follows (in the sách at least):


There are two doors in the Gryffindor common room that lead to the dormitories - one boys and one girls. The common room is at the base of Gryffindor tower, which is presumably large enough to accommodate both dormitories within it.
There are seven total levels which can be reached via a spiral staircase (well, two staircases, one boys and one girls). It isn't really described, but I assume the tower is chẻ, phân chia, split in half and two smaller staircases lead up each side, perhaps the fourteen total rooms (seven for each grade level and gender) alternate and take up the middle section of the tower.

The order of the dorms is not based on year, instead it alternates so each năm stays in the same room for the whole time. Harry's dorm is on the hàng đầu, đầu trang floor.
