In general, the height of dormitory wallpaper of 50 cm is the most suitable. On the one hand, because the size of the wallpaper is 50 cm wide, the wallpaper is pasted horizontally, and no material is wasted.

On the other hand, the wallpaper paste height of 50 cm just blocks the place where the bed often contacts, and also just prevents the bedding from touching the wall. So posting like this is definitely economical!
