Is the hotel room 15-20 square meters large? How big is 20 square meters?

No matter what level of hotel, the room size is different, which is designed according to some statistical data. Naturally, there is a room of 15-20 square meters, but there are also rooms larger than this. Generally speaking, the higher the level, the bigger the room. In the past, the lower the level of rooms in low-level hotels, the bigger the rooms, commonly known as "cart shops". Now, China has cancelled the first-class and second-class hotels. The lowest hotel is a third-class hotel and the highest is a fifth-class hotel, so you will often see the words super luxury and super five-star in the street, but this is just a mystery. In fact, there is no difference in hardware between star-rated hotels, only in service. A room of 20 square meters is generally 4 meters wide and 5 meters long, but in fact, the room area of a hotel is not calculated in this way, but according to the building area or the usable area, because it is neither a square nor a rectangle, but a combination of several areas with different shapes.
