How about keeping the windows of rural houses 2.5 high and 2.8 wide?

Not pretty.

The size of the bedroom window is not fixed, it depends on the size of the room. For a relatively small room, the size of his bedroom window is smaller. For large rooms, the design of bedroom windows will generally increase according to the corresponding proportion.

For a bedroom of general size, the height of the bedroom window is generally 1.5m, and the height of the window sill is generally about 0.9m There is also a certain distance between the top of our window and the window, which is generally about 2.4m above the floor.

When the height of the window sill is less than 0.8m, protective measures should be taken. The width of a window usually starts from 0.6 meters, which is wide enough to form a window. When wide windows are used, the sound insulation in the next room is a problem. If a sliding window is used, the sliding range of the sash should be considered.
